Maritime container terminals are facilities where cargo containers are transshipped between ships or between ships and land vehicles (tucks or trains). 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...

Nowadays, seaports seek to achieve a better massification (massive transportation of containers) share of their hinterland transport by promoting rail and river connections in order to more rapidly evacuate increasing container traffic shipped by sea and to avoid landside congestion. 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...

ABSTRACT Like a living organism, the supply chain is a complex set of entities and systems interconnected by numerous physical, financial and information flows, and, as with all systems there are significant changes that occur over time. 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.

This paper shows a scheduling system written on CLOS which uses waiting queues simulation technique, a discrete event driving, based on an object-oriented approach. This system allows to achieve like another classical simulation scheduling system forward plannings and also backward plannings. Main system feates are given here.

This paper presents a study which analyzes the performances of two scheduling systems using different technics. One of these systems uses waiting queues simulation technic and the other a work order placing algorithm, both systems achieving forward and backward planning. We have analyzed their performances according to different criteria.

In this paper we present our research works centered on a problematic which attract the attention of many researchers and decision maker, which is the traceability of the product. we are interested more precisely to the traceability in the field of goods transportation, by proposing a modeling approach of the relative data to freight, the result of this modeling, was used in the form of a centralized database for the whole of the actors implied in the transport of freight, the base represents the hard core of an information system for the management of the traceability. To ensure the good performance of system and in order to feed our data base with the relative data with the goods transport chain, we propose a solution according to an architecture SOA, based on an exchange of message between the various actors of the freight transport chain.

Our paper processes the case of the subsidiary of car manufacturer who imports containers of constituents (components) of cars to be assembled locally. The road transport of these containers is assured by a company of road transport which has to affect to each reservation, optimally, one or more containers while meeting the deadlines proposed by the customers, the employment regulations and the availability of trucks. Once containers arrived and deposited in a park called “bus station”, upon need, their contents are stripped in various warehouses. To control the various costs engendered during transport and storage of these inputs, our task is to optimize the upstream logistics (before arrival of containers at the containers park) and the downstream logistics of the containers park of our car manufacturer. In this paper, we propose a decision-making tool that will allow the managers a better logistics.

The Dynamic Vehicle Routing Problem (DVRP) is a natural extension of the classical Vehicle Routing Problem (VRP) which consists in designing routes for a fleet of capacitated vehicles that are to service a set of geographically dispersed points at the least cost. In DVRP, new customer demands are received along the day. Hence, they must be serviced at their locations by a set of vehicles in real time. In this research, to solve the DVRP, this later is decomposed into a series of static VRP and then a static solving algorithm which gives a quick and effectively good feasible solution in a given time is applied to each static VRP. This algorithm is a hybridization obtained by combining an Ant Colony Optimization (ACO) algorithm with a Large Neighborhood Search (LNS) algorithm. The computational experiments were applied to 22 benchmarks instances with up to 385 customers and the effectiveness of the proposed approach is validated by comparing the computational results with those earlie...

The exponential growth of the flow of goods and passengers, fragility of certain products and the need for the optimization of transport costs impose on carriers to use more and more multimodal transport. In addition, the need for intermodal transport policy has been strongly driven by environmental concerns and to benefit from the combination of different modes of transport to cope with the increased economic competition.This research is mainly concerned with the Intermodal Terminal Location Problem introduced recently in scientific literature which consists to determine a set of potential sites to open and how to route requests to a set of customers through the network while minimizing the total cost of transportation. We begin by presenting a description of the problem. Then, we present a mathematical formulation of the problem and discuss the sense of its constraints. The objective function to minimize is the sum of road costs and railroad combined transportation costs.As the pr...
