本文首先在对相关研究现状和理论分析的基础上,运用相关的数理统计方法分析货车集结过程中列车车组大小和到达间隔时间的概率分布。在定编集结模式的条件下,构建铁路编组站货车集结的概念模型,并基于Arena软件建立其逻辑模型。最后以金州站为例对货车集结过程进行仿真,以到达金州编组站的实际车组数据为基础,将仿真结果与实际计划相对比,验证模型的正确性与可靠性。
Based on the current research status and theoretical analysis, this paper analyzes the probability distribution of train unit size and arrival time during the process of truck assembly by using the relevant mathematical statistics. Under the condition of the compilation and assembly mode, a conceptual model of truck assembly at railway marshalling yard is constructed and its logical model is established based on Arena software. Finally, taking Jinzhou Railway Station as an example, the truck assembly process is simulated. Based on the actual train set data arriving at Jinzhou Marshalling Station, the simulation results are compared with the actual plan to verify the correctness and reliability of the model.
