This paper focuses on the coping ability of the existing container terminals when mega containerships call at a port. The length of 30,000 TEU (Twenty Equivalent Unit) ships are predicted to be 453 m and occupy 498 m of a quay wall. As a result, the length of berth should be more than a minimum of 500 m. If a 25,000 TEU ship or 30,000 TEU ship call at a terminal, the outreach of QC (Quay Crane) should be a minimum 74.3 m or 81.0 m respectively. As mega ships are calling at the port, the ship waiting time, the available stacking area, and the number of handling equipment can be limited. The analysis reveals that larger ships wait for longer than the smaller ones because they have difficulty allocating the proper seat on berth. As a result of the survey in a terminal, the average occupancy is shown to be 60.4%, the minimum is 52.4%, and the maximum is 73.3%. Surveying the monthly equipment operation rate for 3 years, the average is 85.8%, the minimum is 80.1%, and the maximum is 90.1%. If a mega ship of more than 25,000 TEU appears, the rate will be excessively increased during peak time.

“…However, after gaining knowledge about these operations, the estimated parameters-which describe the operations-might be treated as stochastic while defining an analytical, simulation or numerical model, which would be taken under consideration in particular research. As Iris et al (2018) [7] mentioned, terminal optimization problems are stochastic. As mentioned before, the aim of the issues specified in the paper is to increase knowledge related to the operations in intermodal terminals, and these issues are important elements for simulating the operating process of particular logistics facilities in future research.…”

“…Zając and Swieboda (2015) [2] described a method for distributing containers on the storage yard terminal while unloading a container train, whereas Kostrzewski and Nader (2015) [6] discussed elementary formulas that describe containers allocation in a storage-yard terminal. Iris et al (2018) [7] studied in detail the handling of containers in an intermodal yard. They focused on the problem of ship loading operations in a maritime intermodal freight terminal and aimed at integrating the aspects of operational stowage planning with the assignment and scheduling of transport vehicles, based on realistic and important aspects of the loading operations.…”

The design of intermodal freight terminals requires extensive research and a thorough analysis of the technical, financial and organizational aspects. In the paper, the operation of the reposition of large cargo containers (one of the types of intermodal transport units, ITUs) on the dedicated places is subjected to a discussion. The analysis is carried out with the use of a vehicle equipped with a telescopic arm, such as a reach stacker. The considered storage facility is reduced to a block characterized by spatial accumulation given in the paper. The description of the procedure for the execution of the handling operation from the arrival of a tractor-trailer with a container into a terminal, followed by the ITUs being set aside in a dedicated place and, in the end, the departure of the truck without load, is given in the paper. The activities are described in detail in order to present a descriptive model of particular operations upon entry to the intermodal freight terminal. Moreover, the paper contains relevant figures illustrating the various steps of realization and the analysis of duration of activities supported by actual realizations. The durations of the individual activities described in the paper are experimental, and the results have been validated on real-world intermodal freight terminals. Therefore, the authors believe that the obtained values may be used in analytical, simulation and numerical models of intermodal freight terminals.

“…In addition, in the literature one can find the examples of solving the problems concerning transshipment technologies (e.g., [52]), costs analysis (e.g., [53]), transportation units (e.g., [54]), terminal location [11,12,26,55], selection of the efficient terminal types [56], evaluation of the terminal technologies [16], evaluation of the basic characteristics of the different types of intermodal terminal [10,57], evaluation of the logistics performance for freight mode choice at intermodal terminal [58], measuring the terminal performance [59], optimization of the zones for temporary container storage [60], spatial optimization of the terminal subsystems, i.e., layout optimization [61], etc. The special class of researches deals with the various problems of intermodal terminals, and intermodal transport in general, with the focus on the sustainability, e.g., loading optimization in intermodal terminal considering energy consumption [62,63], terminal location selection for development of the sustainable transport system [64], integration of various technologies in intermodal transport chains (e.g., [65,66]), container routing in a sustainable intermodal transport systems [67], etc.…”

Growing competition in the global market imposes the need for adequate planning of transportation processes and development of intermodal transport networks, whereby intermodal terminals play a key role. This paper proposes a methodology for prioritization of the intermodal terminal's development features, as the procedure in its planning process, leading to the design of the intermodal terminal in accordance with the needs of various stakeholders and the principles of the sustainable development. As the stakeholders often have conflicting interests and objectives, it is necessary to consider a broad set of requirements and developmental features that enable the fulfillment of the defined requirements. In order to solve the problem this paper proposes a new hybrid multi-criteria decision-making model that combines Delphi, Analytical Network Process (ANP) and Quality Function Deployment (QFD) methods in the fuzzy environment. The applicability of the proposed model is demonstrated by solving an example of planning an intermodal terminal in Belgrade.Sustainability 2019, 11, 4102 2 of 20 gained substantial attention in recent years, in academic research (e.g., [5,6]), as well as in practice. For example, the European Union set the goals to shift 30% of the road freight transport over 300 km to other, more environmental friendly means of transport (such as rail and waterborne), by the year 2030, and more than 50% by 2050 [7]. These goals can be achieved only by more intensive development of the intermodal transport.One of the major subsystems of the intermodal transport is intermodal terminal representing the place of storage and transshipment of intermodal transport units between the different modes of transport [8]. Intermodal terminals play a significant role in achieving socio-economic and environmental sustainability [9], and their development has an impact on improving the competitive advantage in the market [10]. Accordingly, requirements, goals and needs of different stakeholders, such as investors, owners, operators of the terminal, terminal users, authorities and residents, have to be in taken into consideration in the process of intermodal terminal planning. Their demands are often conflicting; therefore, a solution that should fit all actors involved is the goal in the planning process. Thus far, the research in the area of intermodal transport planning focused mainly on finding the optimal location for intermodal terminals (e.g., [11][12][13]) or how to improve operational efficiency of inland intermodal terminals [14][15][16]. However, the research related to solving the intermodal terminal planning problems taking into consideration variety of methods is rather scarce. Papers dealing with terminal planning are mainly focused on the intermodal transport network planning or the selection of terminal location. Therefore, the purpose of this paper is to define a methodology that comprehensively examines the different stakeholders' requirements based on which it defines and prioritizes development features ...
