A multi–modal supply chain network design for recycling waterway sediments

0

The French waterway system consists of large navigable rivers and canals connecting many regions. Maintaining a safe navigation channel, in the Nord–Pas De Calais (NPDC) region in France, requires the regular removal of accumulated sediments which are often contaminated with zinc, lead, cadmium, and mercury. New legislations, such as the European Water Framework Directive (DCA, 2000), ensure that disposal should be reduced to minimal level and the waterways sediment should be treated. Such measures increase the research interest to find the potential costumers and create the need for establishing an efficient waterway sediment network. This paper discusses the design of a multi–modal supply chain network (SCN) in order to satisfy the demand of the treated sediments and to respect environmental, social and economic requirements. First, we reviewed models for strategic supply chain network design. After that, we proposed a multi–modal, single period, supply chain network design (SCND) model for waterway sediments problem using a mixed integer linear programming (MILP) approach. Then, results obtained solving a real case SCND model of French waterways (Voies Navigables de France: VNF) in NPDC region are presented. Finally, we present the most important results and future research opportunities.
