铁路集装箱中心站列车装卸作业的仿真研究

Simulation Study of Loading/Unloading Operation on Train in Railway Container Terminal

铁路集装箱中心站装卸场作为中心站的重要组成部分,其运作效率是铁路集装箱运输竞争力的直接体现。利用离散事件仿真原理,将事件图方法与之相结合建立铁路集装箱列车装车作业仿真模型,并对模型进行验证,并分别考虑了在不同作业模式下中心站内运输卡车数量的配置对装卸设备作业效率的影响。实例仿真结果表明该模型为铁路集装箱中心站资源设施的配置规划提供了一种有效的决策手段。

The loading/unloading operation system is one of the most important compositions in the railway container terminal, and its high operation efficiency directly reflects transportation competitiveness between rail and other modes. Based on the discrete event simulation, combined with the event graphs, a simulation model on loading operation on departure train was built, which aimed to analyze the effect on the efficiency of loading/unloading machine with different number of transport vehicles under various operational modes. According to the simulation results, the model could provide a decision reference to managers planning of how to allocate the resource in the railway container terminal.
