RESUMO

The oil industry is one of the most important and dynamic in Brazil. As the oil industry naturally integrated, we need an appropriate strategic planning to the oil supply chain that consider all its processes, such as oil production, refining, distribution and refined products marketing. Moreover, the oil industry is susceptible to various uncertainties regarding the oil and products price, crude oil supply and products demand. In light of these opportunities and challenges, it was developed in this dissertation a stochastic programming model for the strategic planning of the Brazilian oil supply chain. The model includes refineries and process units, oils and their products properties, logistics and national marketing decisions of oil and products, including uncertainties associated with market price, oil domestic production and refined products domestic demand. Based on the stochastic model a robust model and a MinMax model were formulated in order to compare the performance and quality of the stochastic solution. The proposed models were applied to a real example, with 17 refineries and 3 petrochemical power plants that process 50 intermediate products, intended to production of 10 final products associated to national demand, 8 oil fields, 14 natural gas producers, 1 vegetal oil producer, 13 terminals, 4 delivery points and 278 arches of transport. In the results analysis was used as measures the Expected Value of Perfect Information (EVPI) and the Value of the Stochastic Solution (VSS).
