高速铁路列车运行图新增列车运行线优化方法研究

Research on Optimization Method of Newly-added Train Paths Based on Train Running Diagram of High Speed Railways

我国高速铁路部分线路由于节假日或高峰时期客流激增,需要科学合理地组织列车开行,通过调整列车运行图新增部分列车运行线,以提升运力资源供给与需求的匹配度。以加线成功的列车数量最大为目标函数,考虑列车运行图区间运行时间、停站时间、安全间隔时间及原始列车调整程度等约束,建立列车运行图新增列车运行线整数规划模型,实现新增列车运行线的自主选择。选取京沪高速铁路北京南—徐州东区段为案例研究,结果表明该模型可以实现列车运行线的调整,并选择合适的新增列车运行线组合,具备良好的实用性和有效性,可为后续铁路运营部门的决策提供辅助支撑功能。

Due to the sudden increase in passenger flow during holidays and peak hours on some high speed railway lines,it is necessary to organize trains scientifically and rationally.The matching degree of the supply and demand of transport capacity resources needs to be improved by adjusting the train running diagram to add new train paths.Taking the maximum number of trains successfully added as the objective function and taking into account the constraints of interval running time,dwell time,safety interval time,and original train adjustment degree,this paper built an integer programming model of newly-added train paths to realize the independent choice of new train paths.The Beijing South-Xuzhou East section of the Beijing-Shanghai high speed railway was selected as a case.The results show that the model can realize the adjustment of train paths and select the appropriate combination of new train lines.Both practical and effective,it can provide support for the decision-making of railway operation departments.
