An MINLP formulation for integrating the operational management of crude oil supply

In this paper we integrate the management of crude oil supply at the operational level (i.e., from FPSOs to CDUs), taking into account the scheduling of vessels and operations in a terminal, while handling the non-convexities associated to the blending of crudes. The problem incorporates elements of known problems in the literature: maritime inventory routing and crude oil scheduling. To tackle this problem, we propose an MINLP formulation, which is solved by an iterative MILP-NLP decomposition scheme with domain reduction. The solution strategy is illustrated with a set of instances, that yielded small solution gaps.
