动车段调车作业计划是高速列车维修作业的基本计划之一。本文提出了一个0-1规划模型来解决通过自动计算确定最优SSED的问题。模型以调车作业次数最少为目标,约束条件包括线路占用冲突、调车进路冲突、检修作业时间和调车运行时间。提出了一种改进的粒子群优化算法(EPSO)来求解该优化问题.最后,以上海南动车段为例,对模型和EPSO算法进行了实证研究。优化结果表明,该方法是有效的SSED问题和EPSO算法优于传统的PSO算法的最优性。
The shunting schedule of electric multiple units depot (SSED) is one of the essential plans for high-speed train maintenance activities. This paper presents a 0-1 programming model to address the problem of determining an optimal SSED through automatic computing. The objective of the model is to minimize the number of shunting movements and the constraints include track occupation conflicts, shunting routes conflicts, time durations of maintenance processes, and shunting running time. An enhanced particle swarm optimization (EPSO) algorithm is proposed to solve the optimization problem. Finally, an empirical study from Shanghai South EMU Depot is carried out to illustrate the model and EPSO algorithm. The optimization results indicate that the proposed method is valid for the SSED problem and that the EPSO algorithm outperforms the traditional PSO algorithm on the aspect of optimality.
