| 摘 要： | 为建立能跟踪列车、进路、股道变化踪迹且与车站站场布局及结构无关的车站通用模型,将客运专线车站站场视为由进路和股道这两类个体组成;引入时间参数将谓词/变迁-系统(Pr/T-S)扩充为定时/谓词变迁-系统(TPr/T-S).扩充后的系统既能在仿真中跟踪每个个体的状态变化踪迹,又能描述个体状态变化与时间的联系.基于列车、进路、股道等三类个体和TPr/T-S建立了与车站拓扑和规模无关的客运专线车站通用模型.对徐州东站的仿真试验数据显示了进路、股道等设施的占用情况,仿真时间段内车站进路平均利用率为34%,每列列车都能分配到可用进路,表明所采用的运行图是安全、可行的,也证实了此通用模型的有效性.

| Abstract: | In order to construct a general passenger-dedicated line station model, which is irrelevant to the stations' structure and scale, the station model can be treated as a set of routes and tracks. Predicate/transition-system (Pr/T-S) has been extended to timed predicate/transition-system (TPr/T-S) with the consideration of time parameter. TPr/T-S can be used to track the trace of individuals in the simulation while describing the relationship between individual state change and time. Considering that the general passenger-dedicated line station model is irrelevant to the station's topology and scale, the paper models the relationship between TPr/T-S and individual entities including trains, routes, and tracks. The simulation results of Xuzhou East station show that the occupation and utilization rate of station routes is averagely 34% and there is proper route available for each train during the simulation. The results demonstrate the safety and feasibility features of the adopted train operation diagram and the effectiveness of the general TPr/T-S model. |
