技术站列车编组计划要素t节计算方法的商榷

货车无改编通过技术站的车小时节省t节是计算技术站列车编组计划的要素,其准确性直接影响到计算结果.现行计算方法使t节的取值偏小,实践上也无法操作.本文认为在计算中不应减去t集,通过分析货车在技术站进行无调、有调中转作业的车辆停留时间,并考虑到车辆改编作业成本,修正了t节的计算公式.

Research on Formula of Profits Gotten by Transferring Wagons at Marshalling Yard Without Shunting Operations

The profits gotten by transferring wagons at marshalling yard without shunting operations is an important factor for making freight train formation plan of marshalling yards,whose veracity directly affects the results of the calculation.The existing formula to calculate it makes the value of the profits smaller than the right one and lacks the maneuverability to figure it out.In this paper,it comes to a conclusion that the accumulating time per wagon at the technical station en route should not be taken into account when calculate the profits.According to analyzing the staying time and total costs of wagons at the station for transfer operation with or without shunting operations,the formula calculating the profits of wagon by passing through marshalling yards is revised in order to offer the theory and the method to get the values when making the freight train formation plan.
