Análise de investimentos na cadeia de suprimentos downstream da Indústria petrolífera: proposta de um modelo de programação linear inteira mista

The Brazilian oil industry has gained new momentum with the discovery of large oil reserves in deep waters. Between 2011 and 2015 numerous investments in the oil production chain are expected in order to support the scale of this operation. Given this context, investment decisions in the oil industry downstream supply chain gain importance and the use of an analytic tool that encompasses its complexity becomes crucial. Thus, this paper proposes a mixed linear programming model (MILP) developed to allow evaluation of different investment alternatives in the logistics network, whether they approach expanding the capacity of transport, handling or storage. Some features of the model were evaluated through a case study that evaluates the synergies in two projects: the first one to expand the berthing capacity of vessels in a marine terminal and the second to increase the transport capacity of the pipeline linking it to a distribution center.
