Análise da alocação de embarcações de apoio offshore com o uso de heurísticas e simulação de eventos discretos

Abstract

Offshore oil and gas exploration and production activities have imposed major challenges to planning and operation of resources and logistics infrastructure. Proper dimensioning and use of supply vessels are essential tasks to hold an efficient and costeffective operation, since the amount of cargo handled is substantial. In this work, four different approaches for vessels allocation to maritime units and cargos are presented: one known as FIFO rule, two allocation greedy heuristics and one exact optimization method. To be possible compare the approaches the development of a discrete-event system simulator, which represents the operating conditions of Brazilian offshore scenario, was necessary. Associate with the simulator, the selection of a group of indicators that allowed an operation overview. The results evidence the useful of the approaches based on heuristics, because they present values close to the optimization method, but with shorter execution time.
