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. (C) 2018 Elsevier Ltd. All rights reserved.
