高铁列车运行计划检验仿真模型研究

Research on simulation model of high-speed railway train operation plan inspection

研究采用仿真手段快速检验高铁列车运行计划可行性所需的核心模型。模型以改进Petri网为工具,根据高铁列车运行特点及高铁路网功能,分别将列车视为托肯、线路和车站视为库所,通过自定义多种变迁实现列车空间位置变换及运行信息传递。建模基于部件组合思想,考虑列车运行过程中的随机扰动,可根据不同检验需求及所需路网数据快速生成仿真框架并完成系统运行,但仅适用于高铁常采用的单向运行运输组织模式。模拟实例表明模型可开发,模拟结果基本符合客观实际,不仅可检验高铁列车运行计划的可行性,还可作为支撑模型开发具有更多用途的仿真平台。

This paper studied the core model required for testing feasibility of high-speed train operation plan rapidly by the means of simulation.With the help of improved Petri nets,it regarded the train as token,and regarded line and station as place respectively in accordance with the high-speed train operation characteristics and network function.It realized location transformation and running information transfer of high-speed train through customizing a variety of transition.It built the model based on the thought of component combination,considering the random disturbance in the process of train running,simulation framework could be generated quickly and the system operation could be completed according to the different test requirements and the needed network data,but this model was only applicable to the single-direction running transport management mode usually adopted in high-speed railway.Simulation example shows that model can be developed,the simulation results basically are coincide with the objective reality,and it not only can test the feasibility of the high-speed train operation plan,also can be used as a support model to develop the simulation platform with more purpose.
