Research on Optimization of Passenger Train Operation Diagram based on Stopping Diagram

综合考虑在具有客运专线条件下旅客列车的开行起迄点、运行径路、列车等级、开行对数及停站方案,提出基于停站方案的旅客列车开行方案优化方法,并根据相关前提建立优化模型,确定目标函数和约束条件。通过Matlab编程进行实例分析,计算得到干线通道较为满意的旅客列车开行方案,并说明该模型如与已有列车开行方案研究成果相结合,可降低其复杂性,计算速度更快,结果更加直观。

By considering the operation departure-arrival point, operating route, train class, operation sets and stopping program of passenger trains under DPL condition, this paper puts forward the optimization plan of passenger train operation grogram based on stopping grogram, establishes the optimization model according to relative precondition and determines the target function and restriction condition. Through example analysis by Matlab programme, the approving passenger train operation program of trunk line is calculated and achieved, which explains that if the optimization model combined with existing train operation program, the complexity of the model could be reduced, calculation speed could be accelerated and the result could be more intuitionistic.
