摘要
运行图稳定性评价问题是当前运行图理论研究的重要方面,也是运运输生产实践中计划与调度部门一直以来重视的问题。引进着色赋时Petri网(CTPN)分别对列车的区间行驶和车站作业两部分进行系统建模,结合运行图适应度评价指标,利用Exspect软件对建立的模型进行了仿真分析,实现对运行图稳定性评价的目的。以京津城际客运专线为案例,对运行图进行稳定性评价,结果表明基于文中着色赋时Petri网的运行图稳定性评价方法是有效可行的。
For the preparation of high-quality timetable and rail operators scheduling needs,the stability of timetable was analyzed and methods that could further improve its stability were put forward,which became a big problem to the railway sector for a long time.The definition of evaluation timetable stability problem was put forward and the solutions were also proposed.A colored-timed Petri net（CTPN） for the train simulation model structures was introduced： train runs in the range of operation and a train runs in the station respectively.To establish timetable stability evaluation simulation platform Exspect software was used.Based on this platform,taking the Beijing-Tianjin passenger line for an example,through simulation,the evaluation result was worked out.The result shows that the timetable stability evaluation method based on CTPN is effective and feasible.
