This section contains an overview of the different functional areas of a marine container terminal and a summary of the main types of container handling systems. The main advantages and disadvantages of each type of handling system are also summarized without focusing on technical details. 2.1 Functional Areas of Terminal Operations As every other terminal, a container terminal is a complex sys...

International sea-freight container transportation has grown dramatically over the last years and container terminals represent nowadays a key actor in the global shipping network. Terminal managers have to face with an increasing competitiveness among terminals, which require more and more efficiency in container operations both along the quayside and within the yard: the objective is usually ...

Abstract Background In 2017, smaller container ports handled approximately 22% of total containerized cargo. Nowadays liner operators are calling on those with larger ships and demanding fast efficient turnaround the in port. This is possible only if berth has right capacities, working properly achieves a good productivity level. Methodology Productivity level does not depend quay crane capacit...

As the world container volumes are soaring, container terminals form a very important chain in the global transportation network. It is a generally accepted view that the modelling of the dynamic and stochastic nature of the container terminal systems using analytical or closed form models is a complicated process and the use of such models is very limited. Hence, this paper presents a simulati...

Vessel discharge and load jobs in a container terminal can be divided into sequences, one for each assigned quay crane (QC). A QC sequence lists containers in their desired handling order. The common practice for operators is to make do with just this sequence, without generating a job schedule (i.e. desired start-times of handling each container). Operators who need job schedules generate crud...

Two optimal algorithms, MTA* and MT-RBA*, are presented to find the optimal yard crane (YC) job sequence for serving a fleet of vehicles for delivery and pickup jobs with scheduled deadlines and predicted vehicle arrival times. The objective is to minimize the total tardiness of incoming vehicle jobs. This is important for minimizing vessel turnaround time. In the search for an optimal job sequ...

Over the last years, international sea freight container transportation has grown dramatically and container terminals play nowadays a key role within the global shipping network. Terminal’s operations have received increasing interest in the scientific literature and operations research techniques are more and more used to improve efficiency and productivity. In this work we provide an overvie...

A container terminal is a facility where cargo containers are transshipped between different transport vehicles. We focus our attention on the transshipment between vessels and land vehicles, in which case the terminal is described as a maritime container terminal. In these container terminals, many combinatorial related problems appear and the solution of one of the problems may affect to the ...
