In this paper, we propose a mixed integer linear program for the design and planning of a multi-echelon, multi-commodity production-distribution network with deterministic demands. Within a strategic time horizon, this study aims to help strategic and tactical decisions for each period of time: opening, closing or enlargement of facilities, supplier election, flows along the supply chain network. Several families of products, with bills of materials, are considered. We present one application of our model: how to plan the expansion of a company which has to face increasing demands. We report numerical experiments with a MILP solver.
