新型动卧列车开行与4小时综合维修天窗设置研究

Operation of New High-Speed Sleeper EMU Train and Setting of 4-Hour Comprehensive Maintenance Window

针对高速铁路夜间列车运行与综合维修天窗间严重冲突制约夜间列车开行数量和综合维修质量的问题,笔者采用线性整数规划的方法,以动卧列车总旅行时间最小化为目标,构建了列车运行图与综合维修天窗一体化优化线性规划模型,使用CPLEX求解器进行求解,结果显示以现有的京广高铁列车运行图为基础,能够求解出新型动卧列车适应于4小时综合维修天窗开设的列车运行图与天窗设置协调方案。研究结果表明新型动卧列车开行夜间列车后能保证京广高铁每个区间均能开4小时的综合维修天窗,满足每日开行的综合维修质量要求。

In view of the serious conflict between night train operation and comprehensive maintenance window of high-speed railway,which severely restricted the number of night train operation and comprehensive maintenance quality,a linear programming model for the integration of train diagram and comprehensive maintenance window was established,with the goal of minimizing the total travel time of high-speed sleeper EMU train.The model was solved by CPLEX,and the coordination scheme between the train diagram and comprehensive maintenance window setting of the new high-speed sleeper EMU train suitable for the opening of 4-hour comprehensive maintenance window was solved,which was based on the existing train diagram of Beijing-Guangzhou high-speed railway.The results show that the new high-speed sleeper EMU train can ensure that the comprehensive maintenance window can be opened for 4 hours in each section of Beijing-Guangzhou high-speed railway after running night train,and meet the requirements of comprehensive maintenance quality for daily operation.
