为研究列车到达不均衡性、编组辆数和列检工作组织对编组站到达场待检时间、列车技术作业时间和列检人员利用率的影响，提出了基于编组辆数的列车接入时间、制动机试验时间和技术检查时间的表示方法，应用统计分析理论对列检作业的各项时间指标进行数量建模，建立了基于Arena的铁路编组站列检作业微观仿真模型. 仿真分析发现，列车到达不均衡性和列检工作组织是影响待检时间和列检人员利用率的主要因素，列检工作组织对技术作业时间有显著性影响，编组辆数对待检时间、列检人员利用率和列车技术作业时间影响均不显著.

Microscopic Simulation Modeling and Analysis on Train Inspection Operation in Railway Marshalling Station

In order to analyze the influencing factors of waiting time for inspecting, train technique process time and train inspection stuff utilization ratio in different conditions of train arrival imbalance, marshalling numbers and train inspection work organization, the time index representation method of train access, brake testing and technical inspection are presented based on marshalling numbers, the quantitative models of various time indexes of train inspection are setup by principles of statistics, and a microscopic simulation model of Train inspection operation is proposed for railway marshalling station based on Arena simulation software. Simulation result shows that the main influencing factors of waiting time for inspecting and train inspection stuff utilization ratio are the imbalance of train arrival and work organization of train inspection, the work organization also has significant influence on the time of train technique process, marshalling numbers has no significant influence on waiting time for inspecting, train technique process time and train inspection stuff utilization ratio.
