基于动车组接续的高速铁路列车停站方案设计研究

Research on the stopping plan design of high-speed railway train based on EMU connection

对于高速铁路列车停站方案的优化问题,在满足各个车站客流需求的条件下,在开行列车数量一定时,以完成当日运行任务所需动车组数量最少和旅客旅行时间最短为目标,构建列车停站方案设计的混合规划模型,并采用设计的人工蜂群算法求解。基于哈大高铁的相关数据设计列车停站方案,并对其进行优化。相比于初始解,优化后的列车停站次数减少10.9%,越行时间增加1 h,动车组数量减少30.4%,实例证明,所建模型和设计的求解算法对优化停站方案和减少动车组数量均是有效、正确的。提出的新的考虑动车组数量的高速列车停站方案设计优化方法,可为铁路运营决策者编制高速列车开行方案提供有价值的决策支持。

A mixed integer programming model was constructed.Taking the minimum number of the EMUs and the minimum passenger travel time as the optimization goals,with the number of the trains settled,considering the requirement of the passengers at all of the stations,the train stop plan design problem was solved.The designed artificial bee colony algorithm was applied to solve the model.The train stop plan was generated based on the data of Haerbin-Dalian high-speed railway and optimized.Compared with the initial solution,the number of stops was reduced by 10.9%.The crossing time is increased by one hour.The number of EMUs is reduced by 30.4%according to the solution plan.It proves that the constructed model and the designed algorithm are effective and correct for the optimization of the stop plan and the number of EMUs.This paper provides a novel approach to design and optimize the high-speed train stop plan in view of the number of the EMUs,to provide decision support for the railway operation decision makers in the design work of the high-speed railway service plan.
