Short-Term Crude Oil Scheduling Modeling and Algorithm with High Fusion Point Oil and Two Pipelines Transportation Based on Priority-Slot

摘要

Some oil refineries arrange low fusion point crude oil storage tanks and high fusion point ones at two different locations. Different fusion point crude oil needs different pipeline to transfer. So, to transport diverse fusion point oil needs two pipelines. Because of the constraints resulted from transferring high fusion point oil, to schedule such an organization is hard. This paper proposes a new MINLP formulation with transferring high-fusion-point oil and two pipelines transfer that is based on single-operation sequencing (SOS). This formulation aims at minimizing the sum of high-fusion-point oil transfer cost. Simple two-stage MILP-NLP heuristic method cannot be applied to solve the model, so we give an iterative algorithm directly using MINLP solver DICOPT to solve it.
