Prise en compte des politiques de transport dans le choix des fournisseurs

Abstract : The decision of supplier selection is strategic because it impactes the total performance of the company and the purchasing cost represents 40 to 80 % of the total cost of the product. A literature review in this field shows that studies which considered, in an explicit way, the impact of transport on this decision are scarce. This represents an important limitation because splitting orders among multiple suppliers implies important transport costs. Moreover, transport and inventory are highly interrelated and generate costs incurred in the suppliers while the products wait to be shipped, costs incurred by the products in transit and those incurred in the buyer while the products wait to be used. In addition, transport has an impact on the leadtime. Finally, transport takes a great place in the current context of durable development. To study the transport policies impact on the supplier selection, we begin our research with a bibliographical analysis on the supplier selection problem, on the various freight transport characteristics and finally on transport and the buyer/supplier relations. We then propose modeling the problem by a mathematical program which minimizes the product total cost , resulting from transport, ordering, purchasing and inventory costs, under supplier, transport and buyer constraints. Several scenarios are presented for the model validation. At the end, we propose a multiobjectif approach which minimizes simultaneously the cost and the leadtime criteria.
