Ports, from the simple physical sea/land interface they once used to be, have successively turned into commerce and industrial centers, then into logistics and distribution platforms, and are now becoming intermodal nodes in international supply chains networks, the efficiency of which now drives trade competitiveness. With her distinguished location, logistics infrastructure and well qualified…
Turnaround time, defined as the total time spent by a vessel within the port area, is one of the most important key performance measures for a container terminal. In this paper, the authors propose a hybrid approach based on simulation and genetic algorithms to investigate vessels’ turnaround time in a real container terminal under different scenarios characterised by increases in containers …
In this paper we consider the performance evaluation of ship-berth link in port. The efficiency of operations and processes on the ship-berth link has been analysed through the basic operating parameters such as berth utilization, average number of ships in waiting line, average time that a ship spends in waiting line, average service time of a ship, average total time that a ship spends in por…
Container terminal performance is largely determined by its design decisions, which include the number and type of quay cranes, stack cranes, transport vehicles, vehicle travel path and stack layout.We investigate the orientation of the stack layout (parallel or perpendicular to the quayside) on the throughput time performance of the terminals. Previous studies in this area typically use deter…
The paper outlines the results of research aimed at developing an efficient simulation modelling capability for seaports and inland freight terminals. By providing the domain-oriented process of simulation modelling with a uniform and coherent methodological basis and integrating it with artificial intelligence concepts, it was possible to construct a powerful tool-TRANSNODE. This is a decision…
Yard planning is essential for efficient operations in container terminals, especially for ports with limited storage space. To improve the utilisation of space and the efficiency of container handling in a terminal, operators require flexible yard space planning strategies to manage job workloads and yard-to-berth transportation costs. In previous studies, the inter-related decision making pro…
At automated container terminals, containers are transshipped from one mode of transportation to another. Automated vehicles transport containers fromthe stack to the ship and vice versa. Two different types of automated vehicles are studied in this paper, namely automated lifting vehicles and automated guided vehicles. An automated lifting vehicle is capable of lifting a container from the gro…
Major ports contain multiple container terminals, sea terminals, train, truck and barge terminal, and empty container depots, operated by different companies. Port authorities try to streamline inter terminal container transport (ITT) within congested port areas by offering expensive common road and rail infrastructure. Alternatively, individual stakeholders can set up private or collaborative …
Container terminals play a signicant role as representative logistics facilities for contemporary trades by handling outbound, inbound, and transshipment containers to and from the sea (shipping liners) and the hinterland (consignees). Capacity planning is a fundamental decision process when constructing, expanding, or renovating a container terminal to meet the demand, and the outcome of this…
Assessing the potential demand for container ports and related multimodal transportation is critical for several purposes, including financial feasibility analysis and the evaluation of net economic benefits and their distribution.

Truck queuing at marine terminal gates has long been recognized as a source of emissions problem due to the large number of trucks idling. For this reason, there is a great deal of interest among the different stakeholders to lessen the severity of the problem. An approach being experimented by some terminals to reduce truck queuing at the terminal is to provide live views of their gates via we…
In this paper, we study stacking policies for containers at an automated container terminal. It is motivated by the increasing pressure on terminal performance put forward by the increase in the size of container ships. We consider several variants of category stacking, where containers can be exchanged during the loading process. The categories facilitate both stacking and online optimization …
In designing container terminals one have to consider the choice for a certain type of storage and retrieval equipment by performing a feasibility and economic analysis. In this paper, we compare, by means of a simulation study, the performance of manned straddle carriers and automated stacking cranes. As main performance measure, we use the total travel time required to handle storage and retr…
Policy variables, such as security levels at seaports, affect port efficiency in a non-linear way while other factors affecting efficiency at ports such as a number of berths, the area of port yard, and the number of port labors have linear structural relation. Ensuring a certain level of regulations can increase port efficiency, while an excess of the level may result in the reverse of these g…
Multi-Agent systems have been studied extensively, but only a few of these systems are deployed in practice. Essential to get a system implemented is acceptance.

Logistics managers are faced with greater customer volatility, higher customer service expectations and pressure to reduce costs. If these conflicting pressures are to be reconciled, increased supply chain flexibility is vital. Enhanced flexibility is achieved through two types of changes to the supply chain: structural changes, including processes, physical resources and linkages/relationships…

It aims to argue that the managerial decision-making process is an important component in determining the eventual long-term impact of a supply chain disruption.
In micro cold forming, the high degree of technological dependencies between manufacturing, quality inspection and handling technologies leads to an extremely complex planning of process chains. In addition, the lack of standardised processes and interfaces further complicates the planning. The paper aims to discuss these issues.

Simulation has been an integral part of research and development work in container terminal operations. The sheer size of the facilities and the complexity of equipment used make it difficult to predict analytically how the terminal will operate under specific layouts and configurations. Control techniques which relate to the dynamic behaviour of the equipment are even more difficult to analyse…

A multi-purpose cargo terminal in a seaport contains necessary infrastructure to handle different types of cargo, such as container, dry bulk, general bulk, and Ro-Ro. Since such terminals generally have dedicated areas and equipment for different types of cargo, berth, and yard operations for each type of cargo can be considered separate. On the other hand, trucks that carry all types of cargo…
Queuing models and simulation are two primary methods applied to container terminal planning. Queuing models tend to result in underestimated outcomes due to ships and berths not being classified by size and length. This paper classified both ships and berths using actual data and then compared the resultant differences of the scenarios with and without classification with the simulation. The c…
