They can be automated; semi-automated or static ones depend on the type of the equipments that they contain. There are crucial resources at container terminals; the yard, cranes and the vehicles. The yard refers to the temporary storage area where inbound, outbound containers can be stored. While we have two kinds of cranes depending on the type of the yard we are working on: yard crane and quay crane. Vehicles are used to transfer the container between the seaside and yard side (the external trucks XTs are not considerable in our study). The decision of the container stacking position is the most important operational task for the incoming containers which affects not only the productivity of the stacking but also for the later retrieval and also to avoid the unproductive moves to access to the requested containers stored in the sta...

The attractiveness of a seaport to shipping enterprises depends not only on its reliability and nautical qualities but also on its massified hinterland connection capacity. Contrary to what has been observed in Europe, the massification share of Le Havre seaport has stagnated in recent years. To overcome this situation, Le Havre Port Authority is putting into service a multimodal hub terminal linked only with massified modes. In this study, we focus on rail–rail transshipment of this new terminal, specifically on minimizing unproductive situations of cranes to improve crane productivity and to speed up freight train processing. To this end, an improving agent-based engineering strategy called the “crane...

The problem is solved with a Simulation Optimization approach which takes advantage of the great possibilities offered by the simulation to model the real details of the problem and the capacity of the optimization to find solutions with good quality. An Ant Colony Optimization (ACO) meta-heuristic hybridized with a Variable Neighborhood Descent (VND) local search is proposed to determine the assignments of tasks to quay cranes and the sequences of executions of tasks on each crane. Simulation is used inside the optimization algorithm to generate scenarios in agreement with the probabilities of the distributions of the uncertain parameters, thus, we carry out stochastic evaluations of the solutions found by each ant. The proposed optimization algorithm is tested first for the deterministic case on several well-known benchmark instances. Then, in the stochastic case, since no other work studied exactly the same problem with the same assumptions, the Simulation Optimization approach is compared with the deterministic version. The experimental results show that the optimization algorithm is competitive as compared to the existing methods and that the solutions found by the Simulation Optimization approach are more robust than those found by the optimization algorithm.

Besides transportation times for the jobs, empty moving times for the robots are taken into account. The objective is to minimize the Makespan. An ant colony algorithm with appropriate probability transfer structures is proposed. Computational results are presented for test data arising from flow-shop benchmark instances enlarged by transportation and empty moving times.

Also, like a living organism, the supply chain is impacted by many changes, such as, a new customer, a new demand, and resource failures. These changes may happen at different levels, strategic, tactical and operational. Papers sought for this session examine dynamic optimization problems present throughout the supply chain, like Vehicle Routing Problem, Scheduling, Stacking, Planning, Assignment, Stock Management, etc. Papers, which report current research and development, present case studies or challenge the accepted norms, are all welcome. Topics may include, but are not limited to: • Exact optimization; • Metaheuristics; • Hybrid optimization; • Parallel optimization.

Thus, the occurrence of an accidental event causing the interruption of its functioning will affect a large scale of its collaborators. However, the rise of terroristic activities that exploits transportation systems for fraudulent activities makes the risk management process at the keen interest. For this purpose, the aim of this paper is to propose a multi agent framework for targeting high risk containers. The proposed system analyses information provided by several systems to prevent risks. In addition, it enables the assessment of the containers inspections impact on the CT performance. Thus, we integrate the risk management processes in the CT management policy and we simulate its functioning.

This paper describes foundational components that support the construction of these tools. Two di erent tools, an application builder and an authoring system, are presented as examples built on those components.
