Model and algorithm for an inventory routing problem in crude oil transportation
Résumé
In this paper, we study an inventory routing problem (IRP) in crude oil transportation with multiple transportation modes including pipeline and tanker. We consider the problem in a rolling horizon environment with multiple periods as well as the lead-time of transportation and propose a new mixed-integer nonlinear programming model (MINLP). Due to the complexity and large scale of the problem, an effective metaheuristic method GRASP is developed to find near-optimal solutions of the model. Numerical test results of the method are provided.
