考虑高级修错峰的动车组运用计划优化策略研究
首发时间:2016-04-05
摘要:随着CRH系列动车组列车开行规模的扩大,进入高级修的动车组数量逐年递增。高级修通常耗时较长,往往和动车组的日常运用方案相互影响,对协调动车所的调度组织具有重要意义。本文分析动车组高级修相关业务及其与日常运用之间的相互耦合关系,研究考虑高级修错峰的动车组运用计划优化策略。以高级检修到期情况,一二级检修规程和满足列车运行图为约束条件,以实现高级修错峰为优化目标,构建动车组运用计划的优化模型。设计基于粒子群优化的问题求解算法,通过调整动车组的运用计划,实现高级检修错峰的目标,可以为动车所的生产组织提供决策支持。

Reaearch on the Optimization Strategy of Emu's Operation Plan Considering Stagger of Overhaul Peak
Abstract:With the increasement of the Electric Multiple Units (Emu) in service, the amount of those reaching overhaul cycles grows each year. Usually, the overhaul of the Emu consumes much longer time than its daily repair, and has great impact upon the Emu Depots' management. This paper analyzed the relationship between the overhaul and the operation of Emus, discussed the optimization strategy of operation scheme combined with overhaul conditions. An integer model was built to stagger the overhaul peak of Emus, with the overhaul rules, repair regulation level1/2, and train diagram as the constraints. Particle swarm optimization was applied to find better solutions. As a result, adjusting operation schemes contributes to avoiding centralized overhaul and providing decision support for the Emu depot.
