Introduction
Maritime logistics plays an extremely important role in global trade of goods.
According to the International Maritime Organization, 90% of the world trade is carried by the
sea.1 The huge part of all shipped goods falls at those transported in containers. Recent crisis
created challenges for container shipping industry. According to McKinsey&Company 2 research
many shipping companies started to cut costs by different ways in order to regain profitability.
However, these cutting-costs measures influence the quality of service provided to the
customers. Shippers face the problems of lengthening the supply chain, operational complexity,
communications gaps between shippers and shipping companies and others, which emerged as a
consequence of those cost-cutting measures. However, in crisis situation, cutting the costs is not
the only one measure that needs to be undertaken by maritime logistics service suppliers.
Understanding of customers` needs and overall customer orientation is necessary so as to retain
customers.
Maritime transportation service, which shipping company provides to the customers,
include many components. The services that delivered in container terminals play a critical role
in overall customer satisfaction about shipping of goods. Home port and port of destination play
the strategic role of network node in the chain of cargo transportation. The speed of operations in
the terminals directly influences the whole supply chain responsiveness of customer`s business.
That is why, from customer perspective it is important to understand which container terminal
would satisfy the best any particular need. The right choice of terminal would influence the
speed and overall quality of transportation of goods.
The topic of choosing the container terminal is explored in different studies. However,
just a little attention is paid to the issue of customer decision-making process and the preferences
that might differ from one customer to another and that influence the final choice of container
terminal. In our study we are going to look closer to the decision-making process of terminal
selection from customer perspective and provide the benchmarking solution for customer
problem of port selection, according to their specific preferences. Moreover, the subjective
aspect of decision-making process will be explored, which include relational and interpersonal
characteristics.

Therefore, the goal of this paper is to develop a customer-oriented benchmarking model
to choose a container terminal. Within this goal the following objectives are set:
1. To identify the key port`s customers
2. To select the port`s attributes taken into account by the customers when they
assess the port’s attractiveness
3. To conduct a survey of customer typologies based on various criteria and to
develop the customer typology for the ports
4. To select and argument the methodology for solving the port selection choice
problem with regard to the customer preferences
5. To provide a solution for each customer type in the form of benchmarking the
alternative ports
The first chapter is devoted to analyzing the scientific sources for covering the first and
the second objectives. It includes the port evaluation from different parties` perspectives and the
port competition issue. First of all, it helps to identify the main port customers. Second, analysis
of these two parts reveals the attributes that are important for port customers. The research gap is
identified as a result of relevant literature review. In order to cover this gap the answering to the
following 4 research questions is necessary:
1. What kind of typology can be implemented to differentiate different port
customers?
2. How does the process of choosing a port differ from one type of customer to
another?
3. How do relational aspects influence the decision-making process?
4. How to rank the alternatives of ports for each type of customer?
The second chapter of thesis includes the methodological issues. First, we suggest the
hypothetical model of customers` typology for consideration. As a tool for data gathering we use
questionnaire for customers and for industry experts. In this study we use quantitative model,
which allows to rank alternatives. The second chapter includes model description and
specification.
In the last chapter we discuss the main findings and results. The main customer
typologies are defined and ranked alternatives are provided for each type.
1. Review of the state of the art
Choosing logistics service suppliers is a common problem, which businesses face very
often. The role of service providers can be performed by different actors, third-party logistics
8
companies, freight forwarders, shipping companies (maritime, air etc.). In this study we consider
port as a subject of service supply for different groups of customers. Hereinafter, we can use both
terms – a port and a container terminal as synonyms.
The port choice is a process, which implies the element of port competition. In order to
be chosen, ports have to compete for customers. That is why let us start from the defining of
concept of port competition.
The issue of choosing a port was examined in many researches. The process differs
depending on the subject who makes a decision and the criteria which are used to do it. These
criteria that customers considered to be important changed over time. Let us look at this process
more closely.
To start with, it should be noticed that all ports can be classified in terms of the
operations as general ports and transshipment ports. Main functions of the general ports are the
following:
maritime access to navigational waters;
maritime interface to support maritime access through dedicated space
(capacity),
infrastructure (e.g. piers, basins, stacking or storage areas, warehouses,
terminals) and equipment (e.g., cranes)
land access to inland transportation (e.g., rail, truck) 3
For transshipment ports in addition to mentioned functions there is also transshipment
function which implies intermediating role of a port. The containers can be stored in a
transshipment port so as to be delivered in other destination. A port that represents a
transshipment point is often considered a hub port where cargoes are either consolidated or
break-bulked to be delivered to a destination point. The considered in this chapter articles
contain researches either for general or transshipment ports.
In the context of the discussed problem, ports compete to each other to be chosen by the
customers. The concept of competitiveness therefore needs to be considered.
1.1 Seaport competition and competitiveness
The issue of port competition is examined in different studies. However, it is hard to
find one common definition and concept of competition conformably to ports due to its complex

ENVELOPMENT ANALYSIS/ANALYTIC HIERARCHY PROCESS. Journal of Transportation Management, 22(1).

nature and different characteristics that port possesses, according to Notteboom and Yap (2011).
These characteristics depend on the type of port (gateway port, local port, transshipment port)
and type of commodities this port handles (containers and liquid bulk). Moreover, the concept of
port competition can be defined in different ways in accordance with the level at which this
competition takes place. Voorde and Winkelmans (2002) identified 3 such levels: at first level
intra-port competition takes place, when different terminal operators compete within one port; at
the second level, inter-port competition occurs between different ports, however, within one
region or country. The third level is defined when inter-port competition takes place between
different ports which cover different port ranges. It means that ports serve different geographical
areas and customers with no overlapping of hinterland. These differences in the level of
competition, types of port and commodities are among factors that define the criteria, according
to which the port performance is assessed.
One of the important aspects that was taken into account in the most of studies
concerning port competitiveness is the degree of hinterland connectivity. The factor of transport
integration was closely examined in different studies. Ducruet and Van Der Horst (2009) showed
the significant influence of hinterland integration on port performance. Notteboom (2010) also
supported the idea of dependence of level of competitiveness from the inland transport
cooperation. lvarez-SanJaime et al (2014) closely consider the problem of how the port`s inland
transport service integration influences port competitiveness, namely they consider ports as
profit maximizing entities deciding whether to cooperate with road transport companies or not.
They found that despite ports often find it advantageous to cooperate with inland transport, it can
be deleterious to the welfare, as shippers’ aggregate surplus decreases – those who are far away
from the ports benefit at the expense of those who are close to the ports. The authors also suggest
the strategies aimed at eliminating this negative effect: asymmetries in port capacities,
government regulation and efficiency gains.
Port competitiveness itself was examined in some studies considering the problem of
assessing port efficiency. Oliveira and Cariou (2014) revealed that the dependence from the
degree of competitiveness exists, but needs to be examined from the different perspectives:
global, regional and local. They showed that only for regional competition (covering the distance
of 400-800 km) the interdependence is the following: the higher competition, the lower is the
efficiency score.
The concept of competitiveness in the economic sense is closely related to the
performance of a unit, the level of competitiveness of which is assessed. Therefore, let us look at
the concepts of performance evaluation for ports.
10
1.1.1 Physical performance evaluation
Traditionally, port`s performance and the level of competitiveness was considered from
the operational point of view, Talley (2007). It compares optimal and actual throughput over
time, and if the actual one approaches to the optimal one, then it is concluded that the
performance has improved. The optimal throughput is usually defined from the technical
prospective, namely the maximum possible throughput that port can handle under certain
circumstances (or under certain level of inputs). Mostly such evaluation of performance was
widespread in the beginning of the process of containerization, when a lot of investments were
made for the ports` re-equipment, and a lot of studies aimed at analyzing to which extent those
investments were effectively allocated. Performance was mostly associated with port`s
productivity. Thus, ports competed for being more productive with the focus on operational
efficiency. At that time most studies concerned operational efficiency. Neufville and Ysunokawa
(1981) considered 5 container ports in USA for the purpose of its operational efficiency: they
analyzed, how resources, invested in ports, influence the production output. They used
engineering production function method, in which quay length and number of cranes were inputs
and container cargo was an output. The authors also suggest that container ports show significant
returns to scale throughout the range of observations. Williamson and Daunt (1982) explored the
problem of improving the performance in different developing countries. They elaborated the
framework of operational changes which aimed at enhancing port`s productivity. All operational
changes were divided into 2 parts: improvements in operational methods and investments in new
facilities. After, this methodology was applied to different ports and showed as a result higher
rate of cargo handling.
In the last decade of 20th century deeper analyses of port performance were carried out.
They steal appealed to number of containers handled in port as an output, but used more factors
influencing this level as inputs. Tongzon (1994) empirically proved that at least the following
factors are determinants of ports` efficiency: economic activity of the region, geographical
location, frequency of ship calls and terminal efficiency, which represent combined estimate of
efficiency of terminal equipment and resources. It should be mentioned that the abovementioned
studies used so-called “single port” approach, which means that efficiency of particular port was
estimated with no relation to other ports` performances.
The development of the mathematical models which allow to estimate the efficiency of
different decision-making units, made it possible to implement multi-port approach in evaluating
port performance. It means that the efficiency evaluation of a particular ports is estimated in
comparison to other ports. Such analysis as DEA (data development analysis) is commonly used
11
in assessing port`s performance, applying “benchmark” approach. This model uses multipleinputs (which play the role of resources) and multiple-outputs (which result is obtained) in order
to estimate efficiency of resource allocation. The concept of port performance also evolved from
engineering perspective towards broader one. Besides facilities and equipment, that previously
were used as main determinants of production efficiency, other resources (land and labor) were
paid close attention in different studies as well.
The first applications of DEA to maritime industry are dated by early 2000th.
Previously, Roll and Hayuth (1993) applied DEA to ports, although their analysis was not based
on real data. Tongzon (2001) compared and benchmarked four Australian ports and twelve other
international ports in terms of its efficiency by use of DEA-model. He used throughput and ship
working rate as outputs; number of cranes, berths and tugs, number of port employees, terminal
area of the port serve as inputs. Applying DEA-model he found that 10 out of 16 ports were
inefficient and identified the sources of inefficiencies in these 10 ports. This study gives the
framework of how to implement this model in port efficiency assessing, and which kinds of
conclusions and recommendation can be made. The same year, another study of Song et al.
(2001) also showed how to apply DEA to container terminals by looking at those in Korea and
the UK.
Since that moment numerous studies dealt with the problem of port performance
assessing, in different parts of the world, using approximately the same framework. At the same
time, different models and extensions of DEA were applied to the estimating port performance,
with different variables and different concepts of decision-making units. For example, Wang et
al. (2003) and Cullinane et al. (2005) considered a broad series of DEA variants. They
considered and compared results from DEA-CRS (constant return to scale), DEA-VRS (variable
return to scale), and FDH (free disposal hull) models. Moreover, some studies compared the
results from DEA models and other different models. The most frequent comparison is used for
DEA and SFA (stochastic frontier analysis).
Koster et al. (2009) conducted the research, the goal of which was to implement DEA
analysis for assessing real (primary) data and to compare it with the previous research based on
secondary data. The results differed in a large extent in a new research in comparison to the
previous one. The authors conclude that it happened not only because of the usage of secondary
data, which turned out to be non-reliable, but also because researches mix up ports and terminals.
The authors argue that only primary, verified data of port terminals` characteristics should be
used for using in the model. New results showed that larger terminals performed better than
small ones and that those terminals that provided transshipment operations showed higher
12
efficiency scores than those provided export/import operations, whereas in previous studied
result differed in terms of ranking of ports.
DEA is not the only one model, which is used for evaluation of port physical
performance. One of the recent studies uses the concept of TOPSIS (Technique for Order
Preference by Similarities to Ideal Solution), which belongs to the class of multi-criteria decision
making models (Kim and Lu, 2016). The model is based on the calculations of distances from
the chosen alternative to the Positive Ideal Solution (should be the shortest), and to the Negative
Ideal Solution (should be the longest). After the alternatives are ranked according to the results.
In this study authors consider the ports of Busan and Shanghai and aim to compare the
competitiveness of these two ports. The criteria are purely physical and objective – port
throughput and port facilities factors (such as depth, the number of C/C, berth length, the number
of berth, total area, storage area. The results indicated that Shanghai port is more competitive
than Busan port in total competitiveness and in throughput competitiveness, whereas Busan port
has a higher score in port facility competitiveness.
1.1. 2 Economic performance evaluation
However, Brooks and Cullinane (2007) state that in the presence of competition the
physical performance evaluation should be implemented along with economic performance
estimation. The authors suggest that in the competitive environment ports should evaluate
performance from the economic (or financial) perspective. In such situation ports should assess
not only the physical ability to handle the cargo, but also the ability to compete for cargo.
According to authors, in a competitive environment there are two important determinants in the
process of port selection: port charges and time-related costs that both shippers and carriers
incur. Both these actors are willing to reduce these two types of costs. Ports can be distinguished
according to these criteria. If the approach of comparing optimal and actual throughput is used in
the competitive environment, then the optimal one should be defined from the perspective of
economic objective (for example, profit maximizing). Another way to assess port performance is
to compare port performance indicators (benchmarks) that are chosen so as to optimize port`s
economic objective and the actual ones. 4
Indeed, the topic of economic perspective of port competitiveness and performance was
illustrated in different studies. BANÄ OS-PINO and RODRÂIGUEZ-AÂ LVAREZ (2000)
applied stochastic frontier cost function to estimate economic efficiency of Spanish ports. They
found that smaller in size ports and those managed under centralized regime are more
4Brooks, M. R., & Cullinane, K. e. (2007). Devolution, Port Governance and Port Performance. Research in
Transportation Economics series, vol. 17
13
economically efficient. By economic efficiency the authors imply the degree at which port costs
are minimized given a certain output level.
Pricing strategies directly impact economic efficiency, which is, in turn, influences the
competitiveness, according to Marlow (2000). He found that for short shipping price strategies
have implications for competitiveness. He suggested that price differentiation would be based
not on the value of cargo, but rather on the quality of port service (which are the time in port, and
the punctuality of handling the vessel and its cargo). Such strategy provides ports with efficiency
enhance, and in regard to short shipping, ports can compete with road transportation if they use
efficient pricing strategy.
However, commonly used financial ratios are not suitable for evaluating port`s
performance and its benchmarking. Bichou (2006) argued that financial performance can be
overestimated (e.g. high profit) due to some external reasons (such as price inflation, for
example) being not really effective and efficient in resources utilization. Another reason why
port`s financial performance should not be considered alone is that it is used mostly for assessing
short-term profitability, which contradicts the nature and goals of long-term investments.
According to Bichou, there are other aspects which differ from country to country and influence
financial performance, which are access regulation, statutory freedom, access to private equity
and market power. That is why economic perspective of ports` performance evaluation is
relatively less considered in studies rather than physical perspective.
Considered above physical and economic perspective are evaluated from internal
perspective. However, the external assessment from customers` point of view is paid attention in
las years. Let us look more closely on what studies exist on the topic of evaluation of port`s
performance from customer perspective.
1.2 Customers` perspective
Recent research studies, concerning port competitiveness, more and more focus on
customers` perspective in assessing ports` performance, in addition to the physical and economic
perspectives. Understanding of customer needs has been discussed in business and management
studies. At the same time port industry is highly competitive nowadays, that`s why ports are
seeking for sustainable competitive advantage that would give them opportunity to stay steady in
competitive environment. Pardali and Kounoupas (2014) argue that orientation toward market is
14
a key strategic tool for achieving port competitiveness. They assert that right interaction with
customers by means of marketing tools and techniques influence port performance.
According to the Forte (2013), customer-oriented attitude is the approach that ports
should implement to keep and extend hinterland and foreland, and that directly influences annual
cargo throughput. The authors also argue that it concerns not only the relationships that ports
have with its external customers, but also with those within a port. “Internal customers” within a
port environment are all port`s employees who are suppliers and buyers of the services
performed within a port that when brought together contribute to the stream line port operations
and procedures to deliver the services requested by the external customers. 5
Due to existing difference between customers, we can distinguish between customers`
groups, which have different goals, needs and preferences concerning ports` services.
Because of the complex nature of port business and operations let us first identify the
main ports` users. The criteria, which help to identify the port`s competitiveness, depend on the
party, assessing the port.
According to the Talley (2011), key users of port include the following parties:
1) Shippers, passenger and transportation carriers (freight forwarders)
2) Maritime carriers (liner shipping companies)
3) Providers of port services
The last group represents significant part of port users, especially port (or terminal)
operator plays big role for cargo handling because it performs interchanging service for cargo
received from shores and waterways, and vice versa for export operations. The other service
providers of ports are:
1) The stevedore: a company which is hired by shipping line; it provides loading and
discharging cargo from/to the ships;
2) The ship agent: represents ship-owner interests and looks after the ship while it is in
port;
3) The pilot: helps to ship`s master when ship is entering and leaving a port;
4) The towage company: uses a tugboat for the berthing and unberthing of ship to/from
the ports` wharf
5 E. Forte (2013), Economics and logistics in short and deep sea market, Franco Angeli
15
5) Customs broker: clears cargo through customs at a port;
Among above-mentioned users we identify the following customers for ports, which
perspectives we are going to consider: shippers, freight forwarders, shipping companies, port
operators. By shippers we name individual companies which need to transport goods, while
freight forwarder - is a person or a company that organizes shipments for individuals
or corporations to get goods from the manufacturer o r producer to a market, customer or final
point of distribution. 6 Individual shippers often appeal to freight forwarders which are experts in
logistics network, and they arrange transportation of goods by organizing the network,
combining different modes of transportation: rail, road, maritime of air. The liner shipping
company is a carrier that performs regular transportation of goods overseas. 7
Considering the customers` perspective in port competitive environment it is important
for port to maintain and increase customer equity. For achieving these goals it is necessary to
understand, what exactly customers need in ports, what they expect to achieve as a result of a
service, and how they make a decision of choosing a port. In early 90-s a few researches were
conducted by Dalenberg, Daley, Murphy who examined different parties` perspectives in
choosing port, namely the viewpoints of worldwide water ports (1988), water carriers (1989),
U.S.-based international shippers (1991, 1992), international freight forwarders (1992), and
purchasing managers (1994). According to the researchers, the most significant difference in
factors exists between worldwide water ports and the rest of players. U.S.-based international
shippers, water carriers and international freight forwarders also have different perspectives on
significant factors that port should possess. Therefore, we find it reasonable to consider different
parties` perspectives separately.
2.1 Shippers` perspective
Traditionally, it was shippers itself, who made a decision about the choice of a port.
That is why their perspective is considered in numerous studies, with the use of a wide range of
methods. Let us look on how these studies evolve over time.
Slack (1985) in his paper explored different criteria, which could be important for
shippers when choosing a port. He argued that cost factors are not the only one that determine
the choice. The results of the survey he conducted confirmed it. It turned out that among
numerous factors that could be applied to ports just a few matter for the shippers, which are price
and service quality offered by land and ocean carriers. The port facilities were considered as
taken for granted and were not too important for shippers. Interesting result that was revealed is

7http://www.businessdictionary.com/
16
that the minimum price criteria was often mentioned by small companies, whereas for larger
ones quality of service was more important since they wanted to avoid congestion and other
problems that might influence negatively the flow of products. This finding is explainable: large
companies work on a constant basis and with large volumes, which imply economy of scale.
Study also revealed increasing role of shipping lines not only as a direct users of port facilities,
but also as a source of information for exporters and importers of cargo. This study aimed at
defining factors that would determine the carrier, and most of the respondents pointed out that a
port played a role of decision facilitator.
Further studies from shippers` perspective indicated the importance of other different
factors. D`Este and Meyrick, (1992) found that the most important port`s characteristics are:
proximity to point of production, port turnaround time, and availability of appropriate loading
facilities. Such factors as port charges and railway access to the port were hard to identify in
terms of importance because of too much dispersion in answers of respondent. It means that it
highly depends on the particular shipper. There are also factors that were identified to be
relatively important such as tradition of company to ship through a particular port and marketing
initiatives of port management. This study complements the previous one, first considering a port
as a part of logistics network.
However, the problem of a port choice requires not only understanding of which criteria
are important for a customer, but also the order of ranking of these criteria. There is a set of
methods that is commonly used for dealing with a problem of a port choice. The huge part of the
methods belongs to the Multi-Criteria Decision-Making models, which generally imply several
alternatives to evaluate according to a set of criteria (factors or attributes). Such models results in
numeric score that shows overall “attractiveness” of an alternative. The other part of methods
belongs to the regression analysis models, and usually is used to evaluate the probability of
choosing any particular alternative given a set of attributes.
That is why a lot of studies are dedicated to constructing a model, which would result in
the most appropriate solution according to a decision-maker`s preferences. Nevertheless, the
insight on a decision-maker`s preferences about the importance of criteria is of huge importance
as well.
Let us first consider the most frequently used model, when the problem of choice is
considered. Analytical Hierarchy Process, which belongs to the class of MCDM models, is one
of the most used models for dealing with the problem of port choice. AHP is a multi-objective,
multi-criteria theory of measurement. This model implies decomposing of problem on simple
17
components and processing of decision-maker`s estimations. At the beginning the hierarchy is
defined, which includes goals, criteria and alternatives to be estimated according to these criteria.
The elements of each level are pairwise compared and the coefficients of importance are derived.
As a result, the quantitative estimation of each alternative is calculated and the best alternative is
determined.
In this paragraph we consider shippers` perspectives. That is why in the terms of
MCDM analysis in this case a decision maker is a shipper. The authors, who used this model,
and the considered criteria are listed below in the Table 1.

Analytical hierarchy process (AHP) uses rankings of different criteria to model system
of preferences in the selection process. However, other models use different techniques to predict
the choice of a port. For example, discrete choice model (Multinomial Logit Model) offers a
different approach. The theory of discrete choice is developed in a tradition where probabilistic
concepts and formulations play a key role. The model implies predicting possible outcomes of
categorical dependent variables (alternatives), given the independent variables, which can be
binary-valued, categorically valued etc.
Nir et al. (2003) and Malchow and Kanafani (2004) have used the Multinomial Logit
(MNL) model to estimate the effect of important factors on port choice. Tiwari et al. (2003) have
studied the port choice behavior in China by using shipper’s survey data on the discrete choice
model and concluded that distance and port congestions are the most important factors
influencing port choice. Nir et al. (2003) have employed survey data on the model and found that
proximity of port, recent use and port cost are more important in comparison to competition,
frequency, route, port facilities or service. Malchow and Kanafani (2004) have reported that
18
inland distance and frequency of shipments are negatively correlated with the probability of a
port-shipper combination being chosen.
Multinominal logit model was also used for the process of choosing ports in Spain.
Veldman et al. (2011) showed that the location of a port, both in terms of origin and the
destination of its traffic, is the most significant factor for explaining the observed container port
choice in Spain. The authors also considered such variables as hinterland transport costs,
maritime transport costs and broad group of variables for quality of service provided. The
suggested model can also be used for the analysis of cost sensitivity of port choice. The table
below reflects theconsidered factors from shippers` perspective.

To sum up, different methods were used in order to identify the important criteria for
shippers and suggest the best solution for them. The studies and considered factors evolved over
time: starting from considering purely physical characteristics of the ports and costs, and moving
towards looking at the port as a part of logistics network.
19
However, shippers not always directly communicate with shipping lines and choose a
port themselves. More and more companies delegate the logistics function to the freight
forwarders or third-part logistics companies (3PL), which also perform a duty of freight
forwarders. Hereinafter we will name this perspective “freight forwarder”, implying both pure
freight forwarders and 3PL companies. That is why the perspective of freight forwarders needs to
be considered.
2.2 Freight forwarders` perspective
Just a few researchers consider the problem of a port choice from the perspective of
freight forwarders, whereas nowadays they play an important role in this process. Hesse and
Rodrigue (2004) introduced the term “supply chain power” and refer the essence of such power
to the third-party logistics providers (3PL), or freight forwarders due to the fact that “they are
able to command the conditions of delivery that have to be fulfilled by service providers.” 8
Tongzon (2008) also admits the growing power of 3PL in supply chain functioning. Moreover,
Murphy et al. (1992) and Nazemzadeh (2015) found that shippers` and freight forwarders`
perspective, regarding the important factors of ports, differ to certain extent. That is why we find
it reasonable to consider this perspective as well.
Grosso and Monteiro (2008) implemented statistical approach to the problem of
identifying the most important criteria of port selection for freight forwarders. They used factor
analysis in order to define groups of factors. Initially explored 39 characteristics were reduced to
31 due to irrelevance of those 8 ones. Further, these 31 variables were grouped in 4 factors which
are: connectivity of the port, cost and port productivity, electronic information, logistics of the
container. Analysis revealed that the most important criteria for freight forwarders are
connectivity of the port which includes the following characteristics: customs procedures,
electronic customs procedures, followed by customs efficiency, customs hours and fill in and
clear out procedures. This factor also includes road, rail and hinterland connections. Cost and
port productivity factor also plays role in the process of port choosing, but less prominent. This
consolidated factor consists of the 10 variables, among which the most influential ones are road
cost and port charges.
Freight forwarders` perspective was further examined by Tongzon (2009), who found
that for Southern Asian freight forwarders the most important criteria are the following: high port
efficiency, good geographical location, low port charges, adequate infrastructure, wide range of
8Hesse, M., & Rodrigue, J. P. (2004). The transport geography of logistics and freight distribution. Journal of
transport geography, 12(3), 171-184.
20
port services, and connectivity to other ports. Author also provides the analysis of a decisionmaking process, which shows that forwarders first choose a shipping line, and only then they
choose a port among those, served by the line. Moreover, the results showed that ports are not
viewed by the freight forwarders in isolation but are considered together with other requirements
associated with the movement of cargoes across the port-oriented supply chain. The results of
this study complement the results of previous ones, concluding that port infrastructure and
quality of services are also important for freight forwarders.
Freight forwarders as port`s users were also considered by Nazemzadeh (2015) upsides
with shippers and carriers. 3 ports were examined: Antwerp, Rotterdam and Hamburg. The AHP
model was used in order to offer the most appropriate alternative for each type of the customers.
The order of important criteria differs from one group of customers to the other, which is
explained by their respective positions and responsibilities within the supply chain, and the
contract of carriage concerned (carrier haulage or merchant haulage). The overall results indicate
the following order of port selection criteria in decreasing order of importance: port costs,
geographical location, quality of hinterland connections, productivity and capacity. In respect of
general port attractiveness, Antwerp turned to be the most attractive, followed by Rotterdam in
second place, and Hamburg in third.
The studies considered above aim to solve two main problems: first – to identify, which
criteria are important for decision-makers when choosing a port; second – to suggest the best
alternative for a customer, taking into account the preferences about port`s attributes. However,
the list of possible research directions is not limited to these two problems.
According to Mazzarino (2004), there is a class of choice models that deal with the
replicating of the process of choice making. Such models are called process-oriented. In such
models the decision-makers estimate the situation, using qualitative characteristics, goals,
hierarchies of needs, preferences and values, which not always can be mathematically
represented. The sense of process-oriented models is that it tries to analyze, how different factors
which enter decision-making process interact in order to yield results. Such models mostly result
in behavioral framework.
There are just a few studies that emphasize the process of analyzing different port
alternative and the decision making. Mazzarino (2004) considers ro-ro (roll-on/roll-off) sector
(which deals with the shipment of wheeled cargo, such as cars, trucks and so on) for building the
behavioral framework of taking a decision of carrier/port choosing. The author uses qualitative
approach by conducting in-depth interviews and survey among key users of port services –
21
shippers and carriers. After, they come up with the port-shipping choice model in the Adriatic roro sector. The specific of this model is that it gives an insight on how the decision-making
process is built on the different hierarchal level: from the perspectives of shipper or freightforwarder the first-level choice should be made when establishing a partnership agreement with a
shipping company. The interesting fact here is that the shipper/freight forwarder chooses the
shipping company first (which was already noticed by Tongzon (2009)), and only then he makes
a decision about the port, rather than putting port choice decision on the first forefront.
According to the empirical study personal relationships, perceptions, conservative attitude
prevail on the rationality of choices. The second-level choice is made when the shipper/freight
forwarder chooses a port from those suggested by a shipping company. During this stage the
decision-makers mostly concern about the quality of service, rather than about monetary aspects.
Other discoveries regarding the decision-making process are the following:
Decision-makers often are not rationally conscious about the characteristics of
decision-making process. Instead they appeal more to the intuition, perceptions, experience and
other more subjective matters;
Decision-makers of port are quite conservative: once they made a choice, they
continue taking the same choice in other times, thus adopting routine behavior;
Overall, the procedure of decision-making process can hardly be called rational
and formalized, instead, the personal experience and relationships matter. As authors conclude it
demonstrates that the choice process of carrier/port is human activity.
All in all, there is a lack of studies for freight forwarders in the literature, whereas their
role in a decision-making has increased during the last decade. The researches demonstrate the
evidence that freight forwarders` preferences about the attributes of ports differ from those of
shippers. In comparison to the shippers` perspective, studies, concerning freight forwarders
mainly focus on the identification of important criteria of a port, while the problem of the choice
is not underexplored.
2.3 Maritime carriers` perspective
Maritime carriers (or shipping lines) play the intermediate role between shippers/freight
forwarders (end customers) and ports. They represent a party that directly collaborates with port.
They sign contracts with those ports, which are of interests to the end customers. That is why the
perspective of maritime carriers is also paid great attention in the literature.
The first papers of Malckow and Kanafani (2001 and 2003) consider the problem of
port choice of being strongly connected to the problem of vessel choice. The authors state that
while selecting a port a customer indeed chooses the vessel. That`s why in their researches they
22
look at the problem of choosing vessel/port. Moreover, the authors initially assume that a shipper
does not choose a port, but instead, he chooses a carrier, which in its turn already has some port
preferences. Thus, carriers` perspective is explored in the problem of port choice. Because of the
initial assumptions factors, that hypothetically influence port`s overall systematic utility, mostly
reflect vessel`s and geographical characteristics such as: the distance between the port and point
of destination (oceanic distance), the inland distance to the port, the average headway between
voyages by carrier from port to the destination of shipment and others. The multinomial logit
function was used in order to estimate the importance of different characteristics in overall port
“attractiveness”. It turned out that it mainly depends on oceanic distance and inland distance,
whereas vessel capacity is not significantly important. These factors remain significant for
discretionary cargo as well (cargo originating in a region that does not contain a port), but in this
case some other ones can also be important.
Ng (2006) continued exploring this topic and analyzed transshipment ports in Northern
Europe. He carried out the research from the shipping lines` perspective, which are the
permanent users of ports. By carrying out a survey he found out that besides cost and location
criteria, qualitative ones are important. Among others, the most important ones turned out to be:
port infrastructure, advanced technology, availability of dedicated facilities for container
transshipment and the availability of professional personnel in ports.
Yeo et al. (2008) explored the competitiveness of ports in North-east Asia, namely in
Korea and China due to Chinese ports` developments and its threat to be superior to Korea`s
ports. The authors came up with the proper framework of factors influencing port`s
competitiveness form the point of shipping companies. Applying factor analysis they found that
such factors as port service, hinterland condition, availability (which include such sub-factors as
“availability of a vessel berth on arrival in port” and “port congestion”), convenience (namely
“water depth in approach channels and at berth”, “sophistication of port information and its
application” and “the stability of port labor”), logistics cost, regional center and connectivity are
the determining factors for ports` competitiveness in these regions. They also noticed that some
sub-factors that were significant in previous studies have been replaced by other ones. For
example, the key factor has shifted from hardware and labor towards software and technology,
which means that the most competitive ports rely on efficient hinterland logistics systems.
Another attribute that has become important is the availability of a vessel berth on arrival in port,
whereas in preceding studies it was such components as the numbers of loading and unloading
facilities and the capacity of the container yard. The authors conclude that in the considered
23
region shipping companies perceive port service and technology to be not less important than
investments in infrastructure development.
Another perspective from which the problem of port choice is considered is how well
the port is integrated in overall logistics network. Tran (2011) developed the model which
focuses on total costs and aims at minimizing it. In total costs the author includes ship costs, port
tariffs, inland transport costs and inventory costs. He applied brute-force algorithm for solving
this optimization problem on real data: the author considered cargo flows between USA and
Northern Europe. He concluded that the port choice should be assessed not only from the
perspectives of sea port activities and sea routing, but also include inland component.
The abovementioned studies concern mainly the determination of the significant factors
of a port by conduction a survey or factor analysis from shipping line`s perspective. However,
besides the goal of discovery these factors, some studies aim to provide the solution to the
problem of a port choice by implementing the mathematical models. The employed for shipping
lines` point of view models are the same as were implemented for the shippers.
The AHP model was used for predicting the best choice of a port and identifying the
most important criteria in several studies. Lirn et al. (2004) viewed an extensive set of factors
(47) that are attributable to the ports. He distinguished between cost and facility/service factors,
the sub-factors of which are shown in the table below. The author added for consideration the
factor of port management and administration, which was not considered in previous studies.
The author found that the factor of port transportation location is the most important.
Some of the studies suggest high practical importance. For example, Lam and Dain
(2012) suggested a decision support system for port selection, using AHP methodology from the
shipping lines perspective. The authors state that this methodology is advantageous for its users:
“AHP addresses the issue of how to structure complex decision-making problem, identify its
criteria, measures the interaction among them and finally synthetize all the information to arrive
at priorities which depict preferences.” Thus, the line managers can use this system for solving
complex problem of choosing port by utilizing multi-criteria analysis. The suggested model is
web-based and can be used by different decision makers. The system is flexible in the way that
users can choose criteria by themselves and set preferences as well, according to the pursued
purposes and particular cases. The authors claim that such technological advancements would be
beneficial for shipping managers to use because it enhances the service quality of shipping
companies.

Besides AHP model, the MNL model was also used in several studies for predicting a
choice of port from shipping lines` perspective.
25
In the studies from shippers` perspective the generalized discrete choice model was not
developed with the port or transportation industry in mind. The missing element of the direct
application of the MNL framework to model port choices in these studies is the indispensable
element of network. The service network structure, which is a key element of the container port
industry, arises from the main business of a port. The main business of a port, defined in Wang
and Cullinane (2005) as the facilitation of cargo transportation from point of supply to point of
demand, also bestows a critical role upon the port network-connectivity that determines the
competitiveness of a port to a large extent 9.
Tang et al. (2008) covered this gap by implementing one specific model, called
Network-based Integrated Choice Evaluation (NICE) model. This model unites the network
characteristics of the port industry into the multinomial logit preference model (MNL) by the
connectivity index. The considered model uses published schedules from liner shipping
companies to establish the service network of ports and obtain the associated port connectivity
indices. The NICE model also applies factor analysis on observational port attributes (such as
port charges, turnaround time, annual operating hours, water depth and so forth) to derive port
operating dimensions that are mutually and preferentially independent. The NICE model is
empirically determined by expressing the port connectivity index as a conditional MNL function
of these mutually and preferentially-independent port operating dimensions that allows for an
assessment of the marginal contributions of each dimension separately. 10 Empirical results
obtained by applying this model for the process of choice of Asian ports reveal that port
efficiency is most important factor in increasing the attractiveness of ports; other attributes which
are indispensable for a port to perform in order to be competitive are scale economies and
convenience.
Overall, numerous studies dedicate to the perspective of maritime lines in the problem
of a port choice. The results vary from one study to another in terms of the order of important
factors. However, the main ones remain the same: costs, location, connectivity, efficiency and
some other factors. Inside these factors, the sub-factors can be defined, which differ in various
studies. Different methods yield different results.
2.4 Port operators` perspective
Besides external customers` perspective there are a few studies, which examine the port
service providers’ interests in choosing a port. Sanchez et al. (2011) compared the important

26
attributes of users and providers for Latin America and Asia region. They pursued the goal of
evaluating, whether the perceptions of port operators and shipping lines contradict to each other.
They observed that there is a noticeable difference between the perception of port operators
about shipping lines` preferences and needs, and the factual shipping lines` needs. The
differences are significant in monetary cost, geographical location, and, perhaps most
importantly, the speed of ports in responding to the new demands of shipping lines.
11
The same topic of comparisons of different parties` interests was discussed in the study
o f Park and Min who in 2011 proposed a hybrid data envelopment analysis and analytical
hierarchy process (AHP) model that allows to identify factors specifically influencing
transshipment port selection, evaluates the degree of impact of those factors on a transshipment
port selection decision, and then determines the most important ones among various factors. The
analysis concerns both carriers of cargo and port service providers. They first identified port
selection factors through survey, after they indicated the relative weights (importance) of those
factors by implementing AHP model, and after, by using DEA they showed the “contribution” of
each factor to port selection. The main distinction from the previous researches of these authors
is that this model allows identifying the impact of each factor to the port “attractiveness”. They
also showed that in this research cost factor remains important, but at the same time nonmonetary qualitative attributes such as intermodal links and feeder service access are also
significant when identifying port “attractiveness”. At the same time, such characteristic as
technological infrastructure was not revealed as differentiated one. Moreover, the authors proved
again that the importance of different characteristics often depends on the perspective. They
demonstrated this fact by considering the shipping line and port operators` points of view, which
are different in terms of importance of such attributes as port’s proximity to import/export
businesses, port service quality, port security, and port management efficiency. The study
suggests closer and more proper analysis of maritime carriers` needs and preferences for
delivering high-quality service.
1.3 Research gap
Extensive literature review has demonstrated that the problem of port choice was
examined in numerous studies, beginning from the 1980th. As port customers differ, the choice
process, criteria and outcomes vary according to the perspective from which this process is
considered. We considered shippers, freight forwarders, maritime carriers and port operators`
11Sanchez, R. J., Ng, A. K., & Garcia-Alonso, L. (2011). Port Selection Factors and Attractiveness: The Service
Providers' Perspective. Transportation journal, 50(2), 141-161
27
perspective. However, inside this problem there are different issues that were not fully covered in
the existing scientific studies.
In our study we concentrate on freight forwarders and on the choice problem for this
specific group of customers. This group nowadays quite often represents a decision-maker while
choosing a port, moderately replacing shippers. However, just a few studies reveal the factors
that influence decision-making from freight-forwarders` perspective. Furthermore, in
comparison to the other considered perspective, for freight forwarders just one study found that
would deal with the problem of port choice and result in the choice outcome. Moreover, the
review showed the lack of studies that would take into account the relational part of a decisionmaking process, namely, what role do the shipping companies play in decision-making process,
whether they influence the choice? While such groups of factors as costs, infrastructure,
hinterland connection and services are explored in various studies, the relational aspects are paid
attention only in studies, considering specific sectors of maritime shipping industry, but not for
container transportation.
Also, shippers` perspective demonstrated the dispersion in decision-makers preferences
when choosing a port. However, there was no attempt to try to classify the preferences of
different customers. As soon as shippers` perspective is less relevant, we would like to
concentrate on identification of different types of freight forwarders regarding the important
factors for choosing a port.
Moreover, the prediction of choice outcome for a decision-maker, according to his
system of preferences, exists for shipping companies and shippers, but not for freight forwarders.
The scope of models that are implemented for assigning a port for a decision-maker, also lacks
objectivity – those methods need to have numerical values for weights of attributes, which, in
real life is a hard condition to satisfy. That is why we are going to implement in this study one of
the MCDM models, which doesn`t require numeric information about weights of attributes, and
is based on aggregated indices randomization method.
Therefore the research questions are the following:
1. What kind of typology can be implemented to differentiate different port
customers represented by freight forwarders?
2. How does the process of choosing a port differ from one type of customer to
another?
3. How do relational aspects influence the decision-making process?
4. How to rank the alternatives of ports for each type of customer?
28
The research questions are designed to find answers that would cover both theoretical
and practical issues. In general, there is a lack of information concerning a specific type of
customers – freight forwarders, who actually make a decision about port choice. That is why for
ports and shipping companies this study is also appealing as a source of customer needs`
insights.
29
2. Methodology
2.1 Theoretical framework
As the literature review showed, the process of choosing a port varies from one type of
customer to another. In this study we concentrate on the customers, who very often make a
choice - freight forwarders. They make the final choice of the port, which can be completely
their own decision, or, it can be an advice from the managers of a shipping company. It is also
possible that customers can “push” the shipping company to sign contracts with new ports that
appeal the end customers (shippers and freight forwarders). That is why the end customers`
perspective is very important.

Relational aspects
In order to understand the logic of the methodology used, let us present the general
setup of the considered problem, which is depicted on the figure 2.1., and explain the main parts.
A customer considers port not as a separate logistic entity, but rather as a part of the whole
logistic network. That is why it is necessary to consider not only physical attributes of ports`, but
also take into account the services that operators of port provide, the hinterland connection, and
30
relational aspects. We will elaborate with more detailed description of attributes for each port`s
factors in the 3 paragraph.
Customers have certain preferences about the port`s attributes. For some customers only
the costs can matter, while for other ones the hinterland connection is of great importance. The
best alternatives that correspond to the customers` preferences will differ for each type of such
customers` preferences. That is why it is necessary to identify the system of preferences for each
type of customers.
We also include in our model relational part. We will try to understand, whether the
customers make the decision about port choice rationally, or they are highly influenced by
relational (personal) factors. We will include factors that were not previously considered in such
type of studies.
Moreover, customer`s choice is influenced not only by the preferences about port
attributes, but also by the choosing the shipping company. In most cases a shipper comes to a
shipping company, and then, chooses the port among suggested. So, the question arises, how a
customer chooses the shipping company? Namely, what attributes are important in this choosing
process?
The answers to all these questions we will obtain at the end of the research. In the
following paragraphs we will identify the main approaches to data collections that are going to
be used in this study, and then present the mathematical model and tool, with the use of which
we will obtain the ranking of the alternatives for different customers types.
2.2 Hypothetical typology
Literature review and interviews with experts in maritime container shipping allows us
to suggest initial framework of customers` typology. The main distinction criteria are the
following:
Type of cargo transportation: export/import/export-import/inland transportation;
Frequency of contacts: inconstant/constant basis;
The way of decision-making: independent/outsourcing of a decision to a
company/individually, but taken into account the opinion of a company;
We suggest that based on these characteristics several types of customers will be
identified, who share the same preferences about the importance of port`s attributes. The scheme
is presented in the picture below. It has 3 levels: the first distinguishes between occasional and
regular customer, the second – between export/import/export-import operations, and the third –
between the independent decision/individual, but taken into account managers` opinion decision/
outsourcing of decision. We expect that these criteria influence the preferences that freight
forwarders have, and thus will help to identify different types of customers.

2.3 Identifying the type of research
There is a set of methods that could be applied to the business research. In order to
explain, which of them we will be used in this paper, let us consider the following framework of

According to this table, the research we will conduct suits the best for the applied
primary research. First of all, gathering data from customers implies the existence of primary
research, so does the gathering data from the industry expert. As far as in this paper we are going
to solve the specific problem, we use the applied research type.
2.4 Data collection approaches:
In this study we are going to use the following empirical study methods:
1) Questionnaire for customers
2) Questionnaire for expert
As was mentioned above, for carrying out the future research it is necessary to obtain
some data sets from both expert and customers. In order to do it, it is important to decide which
type of gaining data is suitable for each perspective.

2.4.1 Expert`s perspective
First of all, let us consider expert`s perspective and empirical study methods that are
going to be used.
As it was stated in a paragraph above, expert`s estimations are the source of information
about the values of the attributes for the container terminals. Some of this information is going to
be obtained via interviews. In such interview sessions we pursue two goals – to make sure that in
our research we use the same characteristics that are important for the customers and to
understand those characteristics that still are not covered in our research, but they exist for the
customer when making a decision with which container terminal collaborate to. We initially
came up with a set of attributes to apply based on the results of literature review. After, this set
was corrected, taking into account the expert`s opinion.
Interviews were conducted in the very beginning with the purpose of understanding,
how, in general, the procedure of communication with customers is carried out, how customers,
in general, choose port. Basically, interviews were conducted to facilitate further process of
research and for forming of general understanding of a problem.
After attributes are identified, we need to obtain its values. The main factors of port
choice, attributes of which we explore, are presented below. The experts are asked to evaluate the
performance of each port based on different attributes, using the scale from 1 to 5. The
questionnaire for expert is based on the same attributes as customers` questionnaire, excluding
only those attributes that need to be identified by customers itself, due to individual values of
these attributes for every customer. Experts` results are presented in the third chapter of the
thesis.

2.4.2 Customers` perspective
After completing gathering information about characteristics and its values, we proceed
to customers` preferences itself. The questionnaire for customers, in our case for freight
forwarders, contains the following structure:
General information about the client. This information is going to be used as a
base for identification of customer typology;
Port choice criteria. In this part client will evaluate, to which extent each attribute
is important for him when choosing a port.
The ranking of the important attributes;
The ranking of the ports/terminals. Customer can already have certain preferences
about the ports/terminals.
Criteria for the choice of shipping company. Here a customer evaluates different
attributes associating with shipping company choice in terms of its importance.
The questionnaire for customers is attached as an appendix.
In general, the system of obtaining data can be presented the following way:

Obtaining data from customers about their preferences
After completing these steps we can proceed further, namely to describe the model,
which is going to be used, and the method, which underlies the model.
2.5 Quantitative model
The main questions that we want to answer in this chapter are: what we want to measure
and which models and methods can be used for that. After the implementing the methodology
described below we want to get the aggregated quantitative indices that would reflect the
“attractiveness” of alternatives (in our case -ports). These indices will take into account the
36
system of preferences of a customer concerning the importance of the characteristics of the
terminals.
In order to formulate the considering problem in the right terms and then build proper
model let us describe the theoretical model of the problem and its mathematic representation.
2.5.1 Multiple-criteria decision analysis
The model that is used to solve the considered in this thesis problem belongs to the
discipline called multiple-criteria decision analysis (MCDA). We were partly considering it in
the first chapter. This discipline is a part of operations research which deals with the situation
when the decision needs to be made concerning different issues (both for our daily of
professional lives) explicitly taking into account multiple criteria. The problem is most likely
about making choice between different alternatives. Due to existence of multiple criteria there is
no unique optimal solution for such problems; in order to solve it we need to consider the
information about preferences of the decision-maker.
There are different classifications concerning MCDA problems and methods. One of the
basic ones is to distinguish multi-criteria evaluation problems from that of multi-criteria design
(or multiple objective mathematical programming). The main difference is that the former one
has explicit set of alternatives, whereas in the latter ones alternatives are implicitly known. Now
let us process towards the multi-criteria evaluation problems, as we relate the problem described
above to this class of problems.
2.5.2 Multiple-criteria evaluation problems
For such problems each alternative has a set of performance measures for each attribute.
The problem may be defined as finding the best alternative for a decision maker (DM), or
finding a set of good alternatives. One may also be interested in "ranking" or "classifying"
alternatives.
The general procedure within this multi-criteria evaluation problem for solving can be
represented the following way:
37
Fig.3 The scheme of model building
1. Identify alternatives to be appraised
2. Identify attributes
3. Score the attributes for each option
4. To assign weights of importance of
each attributes for each alternative
5. To derive an overall value based on
weights and score for each option
6. Analyze the results
The two main problems arise from the framework stated above: what kind of function
should be used when identifying the overall value based on scores for criteria and weights? What
weights should be used for the analysis? The answers for these questions distinguish the sets of
methods which are used for solving such kind of problem. The last question is of great
importance because in real business or daily life we can hardly indicate the exact values for the
weights of the attributes. Instead, we are likely to use the equalities and inequalities for
identifying which attribute is more important. We proceed to the next paragraph, concerning the
description of model that we are going to use in this study. The method is called aggregated
indices randomization method (AIRM).
2.5.3 Aggregated indices randomization method
This methods belongs to a set of aggregated indices methods, but implies different
approach towards the choosing the weights for the criteria. Let us now briefly explain the
mathematical model of the problem of estimating any complex object, and further to apply this
model for our particular problem of container terminal estimation for the customer.
In the considered model a DM estimates the alternatives, using a set of attributes. Thus,
those alternatives can be called multi-attributes alternatives.
A numerical value of an attribute for a given alternative determines an estimation of the
alternative’s preference, this estimation being a numerical function of the attribute’s value. Such
functions of the attributes’ values are named individual preference indices. Any individual
preference index can be called an individual criterion of preference. That is why, a set of all
individual criteria’s values for a particular alternative determines a multi-criteria estimation of
the alternative’s preference.
The initial assumption of the method used is that each of the constructed individual
preference criterion is necessary, and the whole set of them is sufficient for a numerical
estimation of any alternative’s preference. It means that a numerical estimation of an entire
alternative’s preference is a numerical function of the set of all single preference criteria. Such
numerical function of all single criteria of preference is named aggregated preference index, and
is treated as an aggregated criterion of the alternatives’ preference. Value of an aggregated
38
preference index for a given alternative is its preference estimation which takes into account the
whole set of single estimations of the alternative’s preference. 12
Additionally it is assumed that an aggregative function (i.e. function which determines a
corresponding aggregated index) makes allowance for significance (synonyms: importance,
influence, weight, etc.) of different single performance indices for the aggregated preference
index. Namely, the aggregative function is supposed to be determined by appropriate nonnegative parameters which are named weight-coefficients (“weights”), and which play role of
single indices’ significance estimations.
Briefly, the mathematical model includes implementation of the following steps:
1)
Forming the vector
x=( x1 ,.. .,x m ) of the initial characteristics, any of which is
necessary, and all together they sufficiently represent the quality of the evaluated objects.
2)
q i=q( xi ;i )
Forming the vector
i=1,.. .,m
q=( q1 , .. ., qm ) of individual indices which are the functions
of the corresponding initial characteristics which evaluate the
observable object with the use of m different characteristics
3)
Choosing the form of aggregated function Q(q) , which characterizes the quality
of the project in integrally. It is assumed that function Q(q) depends on the system of weights
w=( w 1 ,.. .,w m ) which are non-negative parameters representing the degree of the importance
of each individual index for the aggregated index Q=Q(q)=Q(q ;w ) .
4)
The defining the system of weights
w=( w 1 ,.. .,w m ) which shows the “weight” of
every individual index q 1 ,...,qm in Q(q) . The additional clause of normalization
w 1 +.. .+w m=1 allows to define w i as an estimate of the relative weight of the individual
index q i , i=1,.. .,m .
Each alternative Ai can be evaluated according to the described above methodology.
Further description of the method has to be connected to the special software that allows
to solve two main important issues concerning the forming of the single preference vector and
choice of weights based on non-numerical, non-exact, non-complete information.
Let us present further this methodology adopted for our problem of choosing.
12Hovanov, N., Kornikov, V., & Seregin, I. (1997, June). Qualitative information processing in DSS ASPID-3W for
complex objects estimation under uncertainty. In Proceedings of the International Conference" Informatics and
Control". St. Petersburg (Russia) (pp. 808-816)
39
2.5.4 Problem formulation in methodological terms
The first step of the methodology presented above is to define
x=( x1 ,...,x m ) of initial
characteristics. For our problem, x stands for the attributes of container terminals which were
stated in the third paragraph, such as road access, the cost of cargo transshipment and so on.
After, the forming of individual indices needs to be provided. In order to use the
software DSS APIS we need the information obtained through the questionnaires from the
company about the values of the attributes of container terminals. This information is
downloaded into the software with the appropriate normalizing function choice.
The type of the normalizing function is defined according to the following rule: if after
increase of the value of the attribute the attractiveness of an alternative increases, then the type of
the function is increasing. In the opposite case, the type is decreasing. For example, the higher
the costs of transportation are, the less an alternative is attractive. In our case only one attribute
has a decreasing function.
After that all information from clients, concerning their preferences about the
importance of different terminals` attributes, needs to be numerically estimated. For this purpose
in the software it is possible to get certain weights based on this non-numeric, non-exact
information for each customer.
The last step is to get the aggregated indicator of overall attractiveness of the object
(container terminal) for the customer according to his preferences (which are already
transformed into numerical weights). After obtaining all aggregated indicators those alternatives
of container terminal can be ranked in descending order for each client.
Moreover, customers can be grouped in different segments according to the type of
shipment, regularity of relationships with shipping company, and preferences. For each type of
the customers the best alternative can be identified. In this case the information about the values
of the attributes should be taken from the experts` interviews.
2.6 Decision support system APIS
For the realization of the method described above, the computer software is used. It is
called DSS (decision support system) APIS (Aggregated Preference Indices System) which is
used for estimation of complex multi-attribute objects of different nature under uncertainty.
Let us list the main advantages of this software for solving our problem:
1)
It allows avoiding the problem associated with different scales of the initial
attributes by forming normalizing function of the individual indices.
More precisely, 2 cases of relationships between the initial attributes and individual
indices of preference are possible:
40
The degree of preference qj is increasing when value of attribute aj is increasing on
interval [MINj,MAXj]
The degree of preference qj is decreasing when value of attribute aj is increasing on
interval [MINj,MAXj]
After formation of monotone normalization functions qj=qj(aj), j=1,…,m, values of all
individual preference indices for all alternatives can be calculated.
2)
It takes into account the absence of exact weights and transform ordinal
information into exact weights with the use of formulas.
DSS APIS differs from the other decision-support systems by allowing to use the
following types of information:
Non-numeric information – non-numeric information (ordinal information) on weightcoefficients values. It can be represented by a system OI(w)={wr=ws;wu>wv;…} of equalities and
inequalities for weight-coefficients.
Non-exact information – non-exact information (interval information) is defined by a
s y s t e m II(w)={aj<=wj<=bj;…} of inequalities and equalities (when a j=bj) for weightcoefficients.
NNN-information on weights – ordinal (non-numeric), interval (non-exact), and noncomplete (incomplete) information on weights is a combination I(w) of non-exact information
(interval information) II(w) on weights and non-numeric information (ordinal information)
OI(w) on weights.
At the end, values of an aggregated preference index Q(q;w) for alternative A(i)
calculated These values are elements of set of all possible values of aggregated preference index
for alternative A(i), (i = 1,…,k).
Alternatives can be ranked according to its aggregated preference index, which is
average aggregated preference estimations. Moreover, APIS allows to get the standard deviations
of the estimations. As a result, APIS provides the graphical representation of the result, which
shows the ranking of all the alternatives for the decision-maker.
Summary
In this chapter we suggested the methodology to be used in our research. First of all, the
type of research is identified – in this study we conduct primary and applied research. The main
source of the data needed is questionnaire – for expert and chosen group of customers – freight
forwarders.
In the very beginning of this chapter we presented the hypothetical model of customers`
typology. It is based on 3 main criteria: the frequency of calling to shipping company, the nature
of decision-making in terms of independency, the type of cargo transporting. It is supposed that
41
each type will have some distinctive types of preferences and thus, different solutions of port
selection need to be provided.
For solving the problem of port selection we use the method called AIRM and the
computer-based program APIS. This program takes into account customers` preferences about
the importance of different port`s attributes, the values of those attributes and the preferences
about alternatives itself (if there are any). The values of the port`s attributes are obtained from
expert. The program allows to aggregate the data into one index that characterizes the overall
attractiveness of the port for a customer. After that it provides the benchmarking of ports for the
considered customer.
The advantage of this model is that it doesn`t require exact numeric information about
the weights of attributes. It generates it itself after obtaining interval and ordinal information
about attributes. Thus, at the end we have the benchmarking of alternatives (ports in our case)
according to the aggregated indices, and also the weights of the attributes, reflecting, to which
extent different attributes are important for the customer.

3. Empirical part
3.1 Data collection
In this study we investigate the customers of ports and shipping companies in SaintPetersburg, and the way, how they choose a port for cargo transportation. For this purpose we
addressed to Maersk Line`s clients, which are mainly represented by freight forwarders and
represent the huge part of all shipping companies and ports` clients. Let us now briefly describe
terminals and ports, which we consider to be alternatives for selection in Saint-Petersburg:
1)
First Container Terminal (FCT). This one is the leader in the field of handling
with containers in Europe. It cooperates with a lot of shipping lines and appears to be one of the
most important transportation point on the route of cargo.
2)
Petrolesport. Petrolesport is a modern technically advanced port complex, which
includes container terminal and ferry terminal. Petrolesport performs all necessary activities for
the container handling: the loading/unloading, storage, forwarding, and handling of various cargo
types, as well as all customs related activities, and other operations. It provides the port services
for all kinds of cargo: refrigerated, ferry, timber, general cargoes, and is one of the leading ports
in the Northwestern Federal District of Russian Federation.
3)
Moby Dick. This port is situated near St. Petersburg, in Krondshtat. It is
comparatively less than above-mentioned ones, but also important because there is always
demand for this port from the customer side.
4)
Sea fish port. This port exists since 1956 and mainly deals with cargo handling
and storage. The port consists of 3 terminals, one of which is constructed for container handling.
The port is situated on the south of Saint-Petersburg not far from high-way
5)
ULCT. (Ust-Lugsky Container Terminal) This container port in one of the largest
in Russia and Eastern Europe with highly technological equipment. It is situated 100 km far from
St. Petersburg, in the Gulf of Finland.
3.2. Expert`s estimations
Maersk Line collaborated with these terminals and ports for a long time. Let us now
present the expert opinion about the values of port attributes that were identified in our
questionnaire.
43
Initially the questionnaire was compiled in such a way so as to completely reflect the
main port`s attributes, which were first identified through literature review, and then verified by
expert. The questionnaire accounted for 19 attributes that need to be evaluated. However, some
of them were excluded due to the equal values for all 5 container terminals. The employed
model, APIS, does not allow to proceed with the equal values for attributes because it means that
the alternatives are indistinguishable for a customer regarding this particular attribute. Due to
this reason we excluded the following attributes: cargo safety, port safety, the absence of drug
cases in a port. Moreover, we could not include those characteristics that have different values
for different customers, for example, existence of personal relations, the proximity to business
(which includes two attributes). These attributes are important for the customers, even if the
alternatives are indistinguishable according to these factors. At the end we obtained 13 attributes
for which we got numerical values from the experts. You can see these values in the Table 3.1.

In general, each of the port has certain advantages and disadvantages. That is why the
choice of a port depends to a large extent to the customer preferences and specific needs.
Moreover, the difference in choice could be a result of initial customer differences, such as
regularity of applying to shipping line`s services or, type of cargo transportation (export/import),
or some other specification. This would result in identifying customer typology.
As for the data from customers, we got 5 different types of answers on questionnaire
designed for customers. The results of these answers we will discuss further in the section
“customer typology”.
3.3. Findings and the results of empirical study
As the results of empirical study we obtained the estimations of attributes of maritime
terminals from the industry expert and the results of survey for the users of these terminals –
freight forwarders. First of all, we provide the analysis of expert estimations in order to
understand, how ranking would look from their perspective. After that we suggest the ranking of
ports for freight forwarders, using APIS. We will see further, whether there are types of
customers, for which the rankings coincide.
3.3.1 Estimation of alternatives from company`s perspective
Having received the values of the attributes from industry expert, we evaluate the
attractiveness of each port from the expert`s perspective, without taking into account the
preferences of customers. We obtain the ranked alternatives, based on the estimations of the
industry expert.
In order to evaluate the alternatives we look first at the sum of values of attributes from
the Table 3.1., and then at the elements of this sum according to the grades (from 2 to 5). We can
see this analysis in the table below.

The table demonstrates that Petrolesport has the highest rank, which is equal to 52,
followed by FCT, ULCT and Moby Dick that share the same place because they have the equal
points. Sea Fish port has only 41 points and due to this fact it is places on the lowest position. It
should be noticed that even if ULCT is ranked the 2 nd, it has some very low estimations of the
attributes (“2”), but FCT and Moby Dick doesn’t have it. Sea Fish port doesn’t have any highestgraded attributes (“5”). The distributions of values of the FCT and Moby Dick are the same (10
for the “5” grade, 28 for “4” grade and 12 for “3” grade).
So we can conclude that from expert perspective Petrolesport is the most attractive port
to choose, followed by FCT, ULKT and Moby Dick, which share the same positions, and at last,
Sea Fish port. As we have conducted this analysis of the alternatives` attractiveness from
expert`s perspective, we can look at the customers` perspective and compare the results.
3.3.2 Customers` typology
We identified 5 types of the customers` preferences based on the importance of different
attributes that customers have. We used the answers on questionnaire about the importance of
different characteristics. Respondents had to estimate the importance of ports` attributes and also
gave their preferences about the ports itself (if they have any). Customers can not give their
preferences about all the characteristics, they just choose those, which are the most important for
them, indicating also others, which are less important. After we look at the attributes that matter
the most for the customers – these attributes form the basis of the typology. Let us present this
typology in the next paragraph.
For further convenience we denote the port`s attributes as follows:

The 1st type of customers` preferences
The first type of customer put on the first places the factors connected to the service and
physical conditions of a port, namely technical infrastructure (X1), special equipment (X2), and
qualified personnel (X6). Moreover, for this type of the customers the recommendations from the
company are important (X12).
After we put into the APIS the preferences of such type, we got the diagram, which
represents the ranked attributes from the most important to the least important. The dash crossing
the red horizontal line indicates the average importance of this attribute for the customer. For
example, for considered type the highest importance (weight) is given for the “qualified
personnel” attribute (X6), and it accounts for 0,32. The sum of all attributes` average weights
equals to unity. We can see that the first 4 positions are taken by 4 attributes mentioned above.
For this type of customer such characteristics as costs, conditions of cargo storage, port
reputation are of the least importance. They care the most about the facilities of a port and
employees, who these facilities support. Such kind of customers transport unordinary cargo,
which require existence of special equipment for loading/unloading of containers.
Diagram 3.1. Ranking of attributes for type 1
Besides the information about the distribution of weights for attributes we also obtain
the ranking of ports, according to the customers` preferences. The Diagram 3.2 shows us the
results. We can see that First Container Terminal is the most preferable and attractive for this
47
customer (it has 0,81 out of 1 score), followed by Petrolesport (0,75 out of 1), ULKT (0,71 out of
1), Moby Dick (0,52 out of 1), and the most non-preferred is Sea Fish port (0,11 out of 1). “The
winner” dominates the second-placed alternative with 100% probability, while Petrolesport does
it with just 55% probability (the blue line indicates it). Sea Fish port has significantly lower
aggregate index, than the rest of ports.
Diagram 3.2. Ranking of alternatives for the type 1
Customer itself in questionnaire chose the following ranking of alternatives: first – FCT,
then Petrolesport, and third, Moby Dick. The obtained from the APIS results coincide with the
preferences from the questionnaire to large extent. However, the diagram shows that instead of
putting Moby Dick on the third place, this customer should rather consider ULKT. In comparison
to expert opinion, Petrolesport doesn`t look like a perfect alternative for this type.
The 2nd type of customers` preferences
In comparison to the first type of customers, the second one doesn`t seek for the
technical infrastructure of a port. For this type costs and port reputation are the most important,
followed by the customer clearing procedure and timeliness of operations.
In the diagram below the single preference indices ranking is shown, by average values
of their weights. It indicates that the most important criteria is port reputation (X11), followed by
expenses (X13), timeliness of operations (X4) and customer clearing procedure (X5). While port
reputation has the weight equals to 0,25, the following 3 attributes have approximately the same
weight around 0,13, as Diagram 3.3 indicates.
Such type of the customers is indifferent to technical characteristics, but care about
simplicity, speed and costs of shipment. He carries technically simple cargo, non-perishable.
What is also interesting is that for this type the existence of personal relations is important to the
large extent. It is not reflected in the table below due to the limitations of the used model.
48
Diagram 3.3 Ranking of attributes for type 2
The results in the form of ranked alternatives are shown in the Diagram 3.4. It indicates
that the most attractive alternative for such type of the customers is ULKT, which dominates the
next alternative with the 71% probability. The rest of alternatives are arranged in the following
order: second – FCT, with the aggregate index equals to 0,65; third – Petrolesport, with the
aggregate index 0,6; the forth position is occupied by Moby Dick, and the fifth by Sea Fish port
with the lowest index 0,2. Such results partly coincide with those, indicated in questionnaire –
ULKT is again not taken into account, while this is the most preferred alternative. The order after
ULKT is indeed chosen by the customers. If to speak about the similarities between this type and
the expert opinion, there is a little similarity, as with 71% probability ULKT is better than FCT,
which is, in turn, better, than Petrolesport with 100% probability.
As this type appraises the most port reputation and costs, ULKT alternative needs to be
chosen. However, customers either are not offered this port or they for some unrevealed reasons
prefer other ports. The attribute of distance for this type is not important, meaning that some
other reasons for not choosing this port can exist.
49
Diagram 3.4. Ranking of alternatives for the type 2
The 3rd type of customers` preferences
The following type of customers is characterized by strong position about storage
services (X3 and X10), customs clearing procedure (X5), and the costs (X13), which represent
the result of efficient storage and customs services. Such type of the customers most often deals
with the import cargo, implying high-quality storage services and efficient custom procedure. He
doesn’t pay much attention to the technical facilities and professionalism of employees. Such
type of customers could transport perishable items.
The order of attributes according to its weights is presented below. The attribute of costs
is put on the first place with the average weight of 0,2, followed by “availability of storage
service”, “customs clearing procedure” and the conditions of cargo storage in port” with
approximately the same weights, around 0,15, as the Diagram 3.5 shows.
Diagram 3.5 Ranking of attributes for the type 3
50
As for the ranking of all ports for such type of the customers, the results are shown in
the Diagram 3.6. ULKT dominates with 100% probability over Moby Dick, which is put on the
second place. The gap between them is quite prominent – ULKT has 0,89 aggregate index, while
that for Moby Dick is 0,58. The third place is given to Petrolesport, with 0,4 index, followed by
FCT and Sea Fish port. Sea Fish port again the most undesirable alternative, and ULKT the most
preferable one.
Diagram 3.6. Ranking of alternatives for the type 3
For this type the results from APIS do not coincide with those obtained from the expert.
ULKT prevails over Moby Dick with 100% probability meaning that for all of the attributes this
alternative is more preferable for this type of customers, than the rest.
The 4th type of customers` preferences
51
The forth type of the customers care the most about before- and after- transportation
service, highly appraising such attributes as convenience of delivery of containers in and
out(X7), qualified personnel (X6), developed transportation network (X8) and timeliness of
handling the containers (X4). Attributes X7 and X6 have the highest position in terms of
importance, and are designated the same weight, equals to 0,25. Developed transportation
network is also important for this type of the customers, in the same extent as timeliness of
services. All the attributes are ranked and depicted in the Diagram 3.7.
Such type of customers concerns the logistical role of a port, which is in our case
represented by the attributes of developed transportation network and easiness of delivery of
containers. Moreover, he cares about the speed of services provided in a port, pointing that
timeliness and qualified personnel are also significant. Such type of customers is constant user of
port services, who has to go there quite often, and because of it he cares about the process of
delivery the cargo.
Diagram 3.7 Ranking of attributes for the type 4
In this case the ranked order of alternatives differs from the previously considered. The
Diagram 3.8 indicates it. Petrolesprt is the leader for such type, which is given the aggregate
index of 0,75, and it dominates the next alternative with 64% probability. FCT follows
Petrolesport, lagging not too much. ULKT is also quite close to the FCT, and has 0,65 index of
attractiveness. Sea Fish port is again the outsider with 0,24 index. It should be noticed that
besides Petrolesport, each alternative dominates the next one with 100% probability.
Diagram 3.8. Ranking of alternatives for the type 4
52
These results correspond to those from the customer questionnaire to some extent:
Petrolesport is chosen indeed most often, followed by FCT. However, ULKT is chosen by the
customers only in the fourth place, while out results show it has the third rank. Sea Fish port is
again ranked to be the leas preferred. If we compare it with the expert results, we can see that
this is the only case, when the results completely coincide. The ranking from expert is 100% the
same, which APIS provides for such type of preferences.
The 5th type of customers` preferences
This type of the customers is also concerned with storage conditions, as the third type,
but also he needs developed transportation network along with the opportunity to choose the
time for taking the cargo. Such type of customers cares about the integrity of port into the whole
logistics network. The problem of choosing the port for such type of the customers is connected
to the problem of logistics optimization, in terms of both costs and location. As storage factors
are important, this type of customers deals with import cargo transportation quite often. He also
might transport special cargo, which needs existence of special condition in storage terminals.
The importance of developed transportation routes might indicate that cargo will further
transported to the distant locations.
The factors of storage services (X3 and X10) are placed foremost and together account
for around 0,5 weight. Developed transportation factor (X8) is also important, but in less extent,
as it has the third position. The opportunity to choose the time for cargo taking out comes after
X8 and has almost the same weight for this type. The attributes and values are depicted in the
Diagram 3.9.

53
The alternatives are ranked in the way as the Diagram 3.10 indicates below. Moby Dick
has become the most attractive alternative for such type of the preferences. It has 0,75 aggregate
index, followed by ULKT, which has 0,71 index of attractiveness. After ULKT the large gap
takes place, and Sea Fish port comes the third with the index of 0,43. Petrolesport and FCT are
ranked the last as the most non-attractive for this type of customers.
Diagram 3.10. Ranking of alternatives for the type 5
The results do not coincide with those, obtained from the questionnaire. They indicated
the preferences of Petrolesport and Sea Fish port over Moby Dick. The reason might be that this
type of customers in the questionnaire indicated that they do not follow any scheme about the
estimating the ports when choosing it. They do not coincide either with those, obtained from the
expert point of view.
Such typology of preferences reflects the difference between existing customers`
preferences. In the second chapter we presented the hypothetical scheme that could be
implemented in order to differentiate customers` preferences. After conducting the survey we
54
identified 5 types of customers` preferences, and now we would like to see, whether the
suggested scheme corresponds to the reality or not, and whether the identified types could be
distinguished according to the considered criteria (the type of cargo transportation, frequency of
appealing to the maritime company`s services, and the independence of decision-making).
3.3.3 Scheme of customers` typology
The factual results indicate that customers indeed differ based on the suggested criteria.
However, the observed typology is different from the suggested scheme. It also has 3 levels, but
with less complicated structure. The real scheme, identified with the use of questionnaire, is
presented below.

The Figure 3.1 above depicts, how the typology of customers is connected to the
general information about customers. In contrast to the suggested in the Chapter 2 scheme, this
one eliminates the occasional customers, who called the service once, seldom, or from time to
time, leaving only the category of regular customers. They include frequent and constant ones.
All 3 types of transportation exist, however, not for every category. For example, the constant
customers usually do either export operations or export-import ones. Frequent customers also
can perform export-import operations, but they also can transport import cargo. Neither of
categories demonstrate the outsourcing of decision about port choice to the managers of the
chipping companies, but two other options take place: customer either make a decision just by
themselves, independently, either they listen to the opinion of the shipping line`s managers, but
make final decision independently. We match up the identified types of customers` preferences
with the abovementioned criteria. For example, the storage services appraisers perform either
pure import or export-import operations: this type of customers` needs excellent storage services
in order to keep the import cargo for some time. However, in order to build more proper scheme
of customers` typology, more customers need to be surveyed.
If to speak about the relational part in the decision-making process, one type of the
customers indicated the importance of existence of personal relations for decision-making, while
the rest finds it unimportant. However, even for that type, which indicated the importance of
personal relations, this factor is not the only one, influencing the decision. Even if some types
indicate that they make the decision, taking into account the recommendations from the shipping
company, only one has denoted the high importance of this factor for decision-making. As for the
order of decision-making, 4 types of customers agree with the statement that they first choose
shipping company, and after a port. But one type has the opposite preferences – port is chosen
first, and the shipping company second. This is the type that seeks for the excellent storage and
customs service.
3.4. Managerial implications
The results of the empirical study indicated that there is a difference in the way, how
freight forwarders choose a port. The difference exists in preferences, concerning attributes of
ports, along with the difference in the process of choosing.
Both for shipping companies and ports the results of this study provide the insight on
how their customers choose a port, what kind of preferences they have, what are their needs. As
shipping companies offer complex solution, including the services of ports, the impression from
port`s services affects overall impression from the shipping company`s services. That is why this
56
is not only ports that are interested in the results of this study, but shipping companies as well.
Moreover, our survey revealed some preferences about the important characteristics for shipping
companies as well. We found that such attributes as ability to track moving of containers, speed
of service delivery, qualification of employees and price affordability are the most important
factors for freight forwarders when choosing a shipping company. It means that freight
forwarders concern not only with the financial issue of the transportation, but the quality of
service delivered as well. Even though in crisis times shipping companies incur cost-cutting
measures, these measure should not be connected to the factors listed above because they are
crucial for customers.
From the ports` perspective, this study gives an insight on how the decision-makers
choose ports. The understanding of factors influencing customers` behavior is essential to deliver
the right services. Our study revealed that not for every type of the customers costs play the
major role. They do, for two of them, but together with other attributes that are not less
important. More and more attention is paid for the quality of service provided, for the storage
services, for the convenience of using a port, and port`s connectivity. That is why ports should
develop not only internal services and facilities, but also do not forget about the importance of
obtaining the access to the main road and rail routes. The port is often not the final point of
destination, and cargo moves further, using different modes of transportation. That is why port
plays important role for overall logistics, and for customers it is of great importance to choose an
optimal port for further cargo transportation.
Delivered in port cargo is left for some time in the storage zone, especially the import
cargo. Some cargo needs special conditions for storage, some cargo are stored for a long time
and because of this customers want to be sure that cargo will be safe. They are also interested in
keeping the costs of storage down because storage costs usually account for large sum of
spending for the container shippers. That is why ports, which offer storage service should further
develop it towards better customer satisfaction. Moreover, such attributes as cargo safety and
port safety turned out to be also important for customers. It means that ports should not forget
about keeping these characteristics on the high level.
Ports should deeply understand the main types of its customers and their needs so as to
suggest better offering for them. As long as the whole industry is turning toward more
technologically developed, ports should also keep up with this trend. Our study revealed that
there is a type of freight forwarders, which seeks for technologically developed services. In
previous studies such findings did not appear. It means that new type of customers started to
appear – those who seek for technological integration of the port. It is not a surprise – more and
57
more freight forwarders itself offer technically integrated solutions to its customers (shippers),
and they expect such type of services from its providers.
From the perspective of freight forwarders, this study suggests the framework to
benchmark the ports, according to the preferences. Using this model, they can choose the most
suitable for them solution, while having an opportunity to look at the overall rank of alternatives
to choose. If customer seeks more the technological services of ports, they should choose FCT.
For the type of customers, which values simplicity and is cost-concerned, the best option is to
choose ULKT. The same alternative is the best for those forwarders, who seek for quality of
storage customs services. Other type of preferences tells about importance of the integration of
port in overall logistics and about the speed of services provided. For customers with such
system of preferences the best alternative is Petrolesport. At last, customers, who care about
storage and logistics state of a port, should choose Moby Dick. A customer with any other
preferences can also get the ranked alternatives, in conformity with system of preferences about
port`s attributes. For implemented model no exact values for weights of attributes are needed,
just the preferences about the importance of different characteristics.
As our study revealed, customers do not use any formal evaluation of ports when
choosing it. However, they have some preferences and needs, which they can rank in terms of
importance for them. They can`t do it for each of the attributes. But they can outline those, which
they appraise the most. Our model helps to identify the most attractive alternative for freight
forwarders, which have only understanding of what they expect from port and the services it
provides.
The considered problem exists not only in the field of maritime transportation, but also
in any other logistics field. In our study we consider services provided by container terminals
and ports. Our methodology can be implemented for other industries, like rail transportation, for
example, for assessing the rail container terminals. The methodology can be extended, but this
study provide the basis for the assessing the terminals from customers` perspective.
3.5 Limitations and restrictions
The goal of this study is to develop customer-oriented benchmarking model to choose
container terminal. The sense of customer-orientation is that we suggest several types of
customers` preferences, which differentiate customers, and present ranked container terminals.
Due to the limited amount of received questionnaires, this study presents a few types of
customers. With higher response rate we could elaborate more proper and thorough typology. It
58
is also possible for future research to see the distribution of customers` preferences in order to
understand, what kind of customers represents the hugest part and the smallest one.
Another limitation and the opportunity for future research is to increase the scale of
estimation of attributes` importance. In this study we used the scale from 1 to 5, which did not
allow us to choose higher precision for estimation of weights in APIS. It is possible to get more
precise estimations of weights, if the scale would be from 1 to 7, or from 1 to 10. However, it
also leads to some difficulties, concerning the way, how respondents could differentiate between
these marks.
Moreover, we could not include such attributes and distances and existence of personal
relations in our model because the respondents did not provide the personal evaluation of these
attributes towards container terminals. In such case, it would be more individual solution, not for
the type of the customers, but more for an individual customer.
In general, the problems of how freight forwarders choose a port/terminals and what
solution can be suggested are underexplored. Different mathematical models can be implemented
for solving a problem of assigning the best alternative to a customer.
59
Conclusions
Shippers and freight forwarders face the problem of selecting a port when they need to
deliver a cargo using the maritime mode of transportation. This decision plays a strategic role –
the right choice of a port could shorten the lead time, reduce costs, increase speed, and overall,
enhance the effectiveness of logistic chain. Thus, it is of great importance to make a right
decision choosing a port that would the best satisfy the specific needs.
In this study we considered the freight forwarders` perspective, as the main group of a
port`s customers. After reviewing relevant literature we found that little attention is paid to this
specific group of customers, whereas in real life a decision on selecting a port is often taken by
them. When considering shippers` perspective, we found that preferences determined on a set of
meaningful to the customer port attributes vary within this group of customers, thus resulting in
different solutions to the problem of port selection. Therefore, it was suggested that preferences
of freight forwarders are also different and, thus, a port selection would vary with regard to the
type of the preferences determined over the port`s attributes.
In order to provide the best solution for each type of customers` preferences we
developed the benchmarking model to choose a container terminal. On the basis of the literature
review and an interview with industry expert, a set of attributes that customers could consider
important for a port to possess was identified. After that we conducted a survey aimed at
revealing the customers` preferences on the importance of port`s attributes and the ports. The
next step was to benchmark ports for each of specified preferences that were detected through
the questionnaire. For this purpose we implemented the AIRM methodology and based on it
computer program APIS.
In this study we identified 5 types of customers, and for each, we provide the solution:
The first type is characterized by the strong need in high-quality infrastructure,
sound port facilities and qualified personnel to manage these facilities.
Moreover, the customer of this type relies on recommendations form shipping
company employees while making his decision choosing the port. For such type
of preferences the best alternatives are: FCT and Petrolesport.
The second type of the customers seeks for costs optimization and good port
reputation and high speed of delivering services. For such type the best option is
to choose ULKT.
60
The same alternative is suggested for the customers, who expect high-quality
storage services and appropriate custom clearing procedure along with optimal
costs.
For freight forwarders, who care the most about the logistics costs and overall
convenience of delivery, the best alternative is to choose Petrolesport.
The five type of the customers, which looks for both excellent storage services
and logistics, the best option - Moby Dick.
Customers` preferences concerning ports not always coincide with those, provided by
APIS. This means that customers do not always follow the rational procedure of port`s
estimation. Moreover, one type of customers pointed out the importance of personal relations,
which can be the determinant of the choice.
All in all, the results correspond to the existing market conditions of Saint-Petersburg
ports, ULKT is known more for dealing with simple and “cheap” cargo, while Petrolesport and
FCT concentrate more on delivering complex services. 13
If to speak about the relational part, we found that there are types, for which existence
of personal relations matter, and for which recommendations from shipping companies are
important. However, this is not the case for every type. Moreover, we found that in some cases
the choice of a port is made taken into account the opinion of the managers of a shipping
company. It means that ports should pay attention not only to the relationships with its final
customers, but also with shipping companies.
Overall, customers concern not only about the price, but also about the service and
logistics. The suggested model would allow to a customer with certain preferences to obtain the
solution of a best-suited port. For shipping companies, this study gives an insight on what
customers seek for when choosing a port and shipping company. The understanding of
customers` needs is necessary for suggesting the best transportation solution. For ports itself, this
study provides the typology of customers` preferences. Ports, thus, can evaluate, which criteria
are needed for improvement in order to satisfy customers` needs. They also can adjust services
for each type of the customers.
The problem of terminal selection appears in different logistics field. Provided in this
thesis methodology of port benchmarking for different types of customers can serve as a base for
the problem of terminal selection in railway industry, for example.

61
To conclude, we achieved the set goal, and answered the research questions. The
customer-oriented benchmarking model is suggested so as to give the best port alternative for
each type of the customers.
