O investimento em umaAbstract: This paper presents two different mathematical formulations for the Supply Chain Network Design of a company responsible for producing and distributing multi-commodity products. Investments in a new manufacturing plant required the readjustment of the company's logistics project, with a necessary re-structuring of the raw materials and finished product flows and the possibility of opening new distribution centers (DCs). The supply chain was modeled using a formulation in mixed linear integer programming, in which the facilities are represented by nodes and the links by the arcs. The computer implementations were performed using OPL and results obtained by CPLEX © solver. The implemented models was validated by a series of computational experiments. We incorporated studies to identify the market demands (market shares) and transportation costs in order to enable the application of models to the company's problem. The application of the models allowed several decisions concerning the initial project of the company to be performed by the project team.
