Abstract

This article focuses on the development of a new linear approximation method for the product of two continuous variables,which is applied to the optimization of crude oil operations scheduling in a refinery supplied by ships. A key challenge in thisscheduling problem is the management of crude oil storage in tanks. Since the storage capacity is limited and there are differenttypes of crude oil with different compositions, it is necessary to store mixtures of crude oils in the tanks. This feature introducesnonlinear and non-convex constraints, which complicate the solution of the mathematical programming models. To overcomethis problem, we have developed a strategy based on piecewise linear approximation using planes, which efficiently handles thenonlinear constraints associated with crude oil blending in tanks.
