    A Shared “Passengers & Goods” City Logistics System

    Many strategic planning models have been developed to help decision making in city logistics. Such models do not take into account, or very few, the flow of passengers because the considered unit does not have the same nature (a person is active and a good is passive). However, it seems fundamental to gather the goods and the passengers in one model when their respective transports interact with each other. In this context, we suggest assessing a shared passengers & goods city logistics system where the spare capacity of public transport is used to distribute goods toward the city core. We model the problem as a vehicle routing problem with transfers and give a mathematical formulation. Then we propose an Adaptive Large Neighborhood Search (ALNS) to solve it. This approach is evaluated on data sets generated following a field study in the city of La Rochelle in France.

    Multi-criteria Decision Making for the Supply Chain Design: A Review with Emphasis on Sustainable Supply Chains

    • Tasseda BOUKHERROUB, presenter, Laboratoire DISP (Décision et Information pour les Systèmes de Production)

    This work presents a literature review on supply chain design (SCD) involving multiple criteria. A special emphasis is given to sustainable supply chains. Our purpose is to provide an overview on the existing works in the sci-entific literature. We are in particular interested in three questions: Which criteria are the most considered in supply chain design problems; especially in sustainable supply chain case? How are these criteria related to the supply chain characteristics? And, which multi-criteria decision making (MCDM) approaches and methods are used to solve such problems?

    Tactical Planning of Procurement of a Supply Chain with Environmental Concern

    • Nathalie Bostel, presenter, Université de Nantes
    • Pierre Dejax, École des Mines de Nantes
    • André Langevin, Polytechnique Montréal

    In this paper, we study the economic and environmental aspects of the tactical procurement planning of an industrial plant within a supply chain, corresponding to a real case of a European company. A procurement plan is obtained by solving an integer linear programming model. Two objectives are used: the first is to minimize the total cost including transportation, handling, and inventory holding cost, while the second is to minimize the CO2 emissions from transport taking into account the distance and the loads of the vehicles. Experimentations performed on the basis of real industrial data validate the approach and allow the analysis of tradeoffs between the two objectives.

    Network Design Model for Intermodal Transport: The Case of the Hinterland of the Port of Cotonou

    • Messan Lihoussou, HEC-ULg
    • Sabine Limbourg, presenter, HEC-ULg

    Since 2006, the Millennium Challenge Account program subsidizes a project to improve the performance of the Port of Cotonou, through modernization of infrastructure and management systems, and strengthening institutional reforms. But the project mainly concerns the port, not the development of its hinterland. However, no port can develop without its links with its hinterland. That’s why we analyse the issues relating to the hinterland transport network. Both rail and road transportation networks will be examined. We also investigate inland terminals in order to build up intermodal transportation which is almost non-operational. Thus, the objective of this paper is to determine the optimal number and locations of the terminals so that the total costs of the distribution network are minimized.
