摘　　要：中欧国际铁路运输是"一带一路"陆路通道建设的核心,而铁路国境口岸站是运输通道的关键节点。随着运量提升,铁路过境口岸站运输组织中存在的问题逐步显现。以提升口岸站作业效率为目的,在口岸站作业流程分析的基础上,以全作业流程平均周期时间最小为目标,建立口岸站作业流程的Petri网模型,利用ExSpect软件对口岸站作业流程进行仿真。仿真结果表明,提出的口岸站作业流程优化措施可以有效提升作业效率。The China-Europe international railway transport becomes the core of construction of the land passage for the Belt and Road Initiative.The railway station becomes the key node of the transport corridor construction.With the gradual improvement of the traffic volume,the critical issues in the transportation organization of the port station gradually appeared.To improve the operation efficiency of the border station,based on the analysis of the operation process of the border station,aiming at minimizing the average cycle time of the whole process,this paper establishes a Petri net model of the operation process of the port station.A simulation is conducted using the ExSpect software.With the analysis of the simulation results,the optimization scheme of the operation process of the port station is proposed.
