论文摘要
与其他运输模式，道路，铁路和船只相比，多乘管道是漫长的途中和晚上运送石油产品的最安全，最经济的方式。在过去的二十年中，操作多驱动管道调度已引起了人们的关注，其中大多数贡献都是基于连续时间表示的。在本文中，我们提出了一个新的离散混合整数线性编程模型，用于以多个炼油厂和配送中心为特征的多重型管道的短期计划。该模型最佳地确定输入节点处产品注射的顺序和计划，产品序列传递到输出节点，并随时沿管道沿管道沿管道的大小和产品位置追踪。所提出的模型还允许在输入节点同时执行注射，并在可以充当输入和输出节点的中间节点上同时处理和交付。两个基准示例问题的解决方案表明，所提出的模型可以大大降低管道运营成本。
Compared to other transportation modes, road, railroad and vessel, multiproduct pipelines are the safest and most economical way of conveying petroleum products over long distances day and night. During the last two decades, the operational multiproduct pipeline scheduling has gained increasing attention, where most of the contributions are based on continuous time representation. In this paper, we present a new discrete-time mixed integer linear programming model for the shortterm scheduling of multiproduct pipelines featuring multiple refineries and distribution centers. The model optimally determines the sequence and planning of product injections at input nodes, the sequence of product deliveries to output nodes, and traces the size and the products location along the pipeline at any time. The proposed model also allows to execute simultaneous injections at the input nodes and to tackle simultaneous injections and deliveries at an intermediate node that can act as both the input and output node. Solutions to two benchmark example problems illustrate that the proposed model presents significant reductions in the pipeline operational cost.
