单管道多油品顺序运输调度优化

管道运输可将成品油从炼油厂输送到靠近市场的分销中心(省市级油库).典型的输油管道通常是一根连接多个分销中心与一个炼油厂的长距离管道,输送过程中油品之间不加任何分离装置,实现多油品顺序运输,因此,油品的运输顺序以及运输规模应当合理安排,以便在有限的资源约束下最大限度地满足市场需求.本文对这类管道运输问题构建了连续时间MILP数学模型,对前人的研究结论进行了改进;通过对问题清晰、准确地描述,使管道运输调度质量显著提高;将所建模型应用于实际案例,其结果证实了模型的有效性--提高了解的质量同时使运算效率得到显著改进.

Optimal Scheduling of Multiproduct Pipeline Transportation System

Multiproduct pipelines permit to transport large volumes of a wide range of refined petroleum products from major supply sources to distribution centers near market areas.Batches of refined products and grades are pumped back-to-back in the same pipeline,often without any separation device between batches.The sequence and lengths of such pumping runs should be carefully selected in order to meet market demands at the promised dates while satisfying many pipeline operational constraints.This paper deals with...
