The alignment among strategic, tactical and operational levels is important in competitive advantage. In Logistics Network Planning the main strategic decisions is the insertion of new facilities in the logistics network, which unfolded to the tactical level, reflects in the decision to allocation of demand, aligning the pre-existing to the new realities of the business structure. This reallocation of demand influences the distribution logistics and entails changes in this activity to minimize transportation costs. This study used the case study of Brazilian fertilizer sector that is been changing due the insertion of new plats called Units Nitrogen Fertilizers (UFN's) in the logistic network from XPTO. The study was limited to urea which is responsible for 60% from nitrogen market in the Brazil. In order to analyze the allocation of demand due the new UFN was used the Classic Transport Problem, minimizing the cost of transportation, therefore optimizing the distribution process of nitrogen fertilizer urea. Transportation Cost is the most important logistic cost and this cost is very representative for urea. After collection of data relative to the case study, were identified transportation costs, demand for urea and destinations, supply capacity and sources of supply. In order to consider changes in logistics network from XPTO regarding the allocation of demand for urea, scenarios simulations with the UFN's insertions were performed. The Classical Transport Problem was applied in the scenarios through software AMPL and the solver CPLEX aiming to solve the optimization problem and changing the allocation of demand as UFN?s were inserted as of minimizing transport cost. The results presented that the inclusion of the UFN-III in XPTO logistics network was responsible for the most significant transport cost reduction among the simulated scenarios, confirming that Logistics Network Planning and the alignment between the strategic and tactical levels are the capable instruments to contribute with the optimization of product distribution urea.
