| Abstract: | A timed colored Petri net (TCPN) simulation model is presented to describe the operating process of railway passenger stations. The TCPN model uses a route conflicting graph to define the station yard in order to solve the problems such as complex modeling process, limited applicable range, and inefficiency, in the system simulation of the current railway station operation. The results of the simulation example show that the TCPN model has the advantages of stability and reusability, and can be widely used in the simulation and optimization of passenger railway stations including high-speed railway stations; the conflicting graph is an accurate presentation of station yard routes, which has the same accuracy as the design of station yard construction, and its precision can reach a millimeter level; compared to the traditional modeling method, the progress of the conflicting graph modeling is more efficient. In the given example, maximum loading rates at station throat area and arrival-departure tracks are 70% and 35%, respectively; on-schedule rates of arrival and departure are 100% and 91%, respectively. |
