RESUMO

This work treats the problem of petroleum transport, extracted from wells and stocked in containers, in order to achieve preprocessing plant. The purpose of this plant is take out the water and salt mixed within the oil, and after send the petroleum treated to refineries which produce derivative products. The goal of present work is to warranty a constant flow rate, at the inlet of the oil treatment plant, in order to avoid fluctuations on the capacity, which have implications on dosing of products, stability of physical and chemical processes that take place within the plant. The methodology proposed consist in a hybrid proceeding, in that the problem resolution is decomposed in T problem steps, one to each interval, and this steps in the problem are resolved sequentially from the first interval through the last interval of time. The first step treats only the problem with integer variables, and the second step of resolution treats only the continue variables. The solution analysis were proposed by means with Genetic Algorithms and Linear Programming, based on applied mathematical modeling, which allows to reach optimal results at a short computational effort. The combinatorial effort is focused on the solutions possibility space to control pumps functioning, with the objective to control the oil delivery from those pumps to the central treatment plant. The selection of each pump contribution is made on the basis of its container own filling regime, which in turn, depends on the wells contribution...
