摘要
通过事件调度的原理构建仿真系统,并给出了路网状态更新矩阵、事件调度模型和仿真评价模型。通过仿真系统能准确的统计列车的延误和路网的能力利用率,并通过仿真结果的分析识别路网的瓶颈,给出瓶颈疏导建议,有利于运行图系统下一步的优化调整。最后,对武广客运专线建立了仿真系统,并通过仿真实验对武广客运专线的实际能力进行评价。
A passenger dedicated line capacity evaluation simulation system is constructed based on event scheduling method. The system contains railway network status updating matrix, event schedfding models and simulation evaluation models. The simulation system can give accurate statistics of the trains＇ delays and railway network＇s capacity use ratio and railway network＇s bottleneck after analyzing the simulation results and give bottleneck eliminating advice which is useful for the timetable system optimization in the next step. Finally, in an empirical study, a simulation system is constructed for the Wu-Guang PDL and a simulation experiment is carried out to evaluate the PDL＇s real capacity.
