矿区铁路集配站车场状态研究

Mathematical model of yard condition of railway marshalling station in coal mining area railway station

针对矿区铁路集配站列车密集到达的实际作业情况,运用排队论理论和运筹学思想,建立了车场状态的数学模型,对集配站到发场充满过程进行了数学描述,为确定集配站在饱和状态下需要的到发线数量提供了新的计算方法,并结合实例进行了验证。研究结果表明,列车密集到达是造成集配站到发场能力紧张的重要原因。研究结论为确定集配站的设备规模提供了依据。

According to the real operational process of trains in the marshalling railway station, the mathematical model for the yard condition is established based on the queuing theory and operational research idea. This model is proved to be with pertinence and availability for the maximal capability based on a real example. The conclusion can be safely drawn that the deed of trains dense arriving is the important factor for the defect of capability. The means can be used to verify the amount of arriving -departure track in marshalling station.
