摘　　要：单管道通常是一根连接多个分销中心与一个集中成品油供应点的长距离管道,输送过程中油品之间不加任何分离装置,且要实现多油品顺序运输。针对如何合理安排油品的运输顺序以及运输规模,使在有限的资源约束下最大限度地满足市场需求,以对问题清晰、准确地描述为基础,构建了连续时间MILP数学模型,并通过实际案例测算证实了所建模型的有效性,不仅使管道运输调度质量显著提高,而且使运算效率得到显著改进。The single pipeline is mostly a long multi-product pipeline system receiving a number of products from a single refinery source to distribute them among several depots without any separation device between batches of refined products. This paper deals with how to schedule multi-product and reasonable batches of products to meet the demand of the market mostly under the restriction of limited resources. By developing a more rigorous problem representation and improving the R. Rejowski Jr＇ model, a novel MILP continuous mathematical formulation was presented. To illustrate the proposed approach, a real-world case study was performed. Compared with previous work, better solutions were found at much lower computational time and the quality of the pipeline schedule was remarkably improved.
