In this thesis a new method of decomposing a four-level supply chain is developed to optimize reconfiguration in soybean grain export chains in Brazil. The decomposition method solves a large and complex problem in infrastructure and operational logistics in a four-level supply chain with two decision makers. The decomposition method is based in three subproblems, two being bi-level mathematical programing models and the other is mono-level mathematical programing model. There are two interested parties in this problem: the investor (usually but not necessarily the government) and the user (the producer). Both parties benefit as a result of the competitive position of the reconfiguration of the soybean grain supply chains in Brazil.
