摘要/Abstract

摘要：

成品油管道的最大特点是采用"背靠背"的方式同时输送多种油品，其运行与管理的一项重要内容是制定批次计划。利用计算机自动优化批次计划对提高成品油管道管理水平与效率具有重要意义。成品油管道批次计划优化问题建模的难点在于如何描述批次在管道内的运移过程以及满足诸多的工艺运行要求。针对单点注入、多点分输油品需求型成品油管道分输计划优化问题，以管道沿线各管段运行流量整体平稳性最高为目标，采用离散时间的表达方法建立了混合整数线性规划模型。模型可满足批次跟踪、管段运行流量、首站输入、中间站分输、末站分输、站场需求等约束条件。为增加优化结果的实用性，模型中引入了两类约束条件：管道沿线任一中间站应既允许执行部分分输作业，也允许执行全分输作业；为减少管道操作人员的工作量，要求在相邻的两个时段内，若同一中间站对同一批次执行部分分输作业，其分输流量应保持一致。以成品油管道历史输油任务为例，成功利用CPLEX软件获得了模型最优解，验证了模型的有效性。

Abstract:

Multiproduct pipelines can simultaneously convey several products by a "back-to-back" way. Drafting batch schedules is an important part of operating and managing a multiproduct pipeline. Using computers to automatically optimize batch schedules is significant to improve the level and efficiency of managing multiproduct pipelines. The difficultly in modeling for optimizing batch schedules of a multiproduct pipeline is how to describe batch movements in pipelines and satisfy processing constraints. Aiming at optimizing the delivery schedule of a single-source and multi-depot multiproduct pipeline based on the oil-demand mode, this paper has established a mixed-integer linear programming model using the discrete-time representation, so as to achieve the overall highest stability of pumping rates in all pipeline segments. The constraints on batch tracking, pumping rates of pipeline segments, injection operations performed by initial station, delivering operations implemented by intermediate and terminal stations, and product demands are all satisfied in the proposed model. For improving the practicability of optimization results, two types of constraints are introduced. The first type is that any intermediate station can not only carry out side-stream delivery operations, but also perform full-stream delivery operations. The second type is that if an intermediate station downloads product from a batch in two successive time intervals by side-stream delivery operations, the delivery rates should be consistent, in order to lessen the workload of operators. Taking the historical transportation task of a certain multiproduct pipeline as an example, the optimal solution of the model is successfully obtained using software CPLEX, which verifies the practicability of the proposed model.
