编组站列车编组顺序的调整方法

The Adjustment Method for Train Classification Sequence in Marshalling Station

编组站出发列车按发车时刻的先后安排的编组顺序有时难以保证每一出发列车均满轴,此时需要调整。在分析编组站作业特点的基础上,以作业时间标准为依据,定义了紧凑接续编组、相邻列车最大调整等概念。由出发列车的最晚必须开始编组时刻分析了发车间隔时间、待发时间与编组作业时间之间的关系对编组顺序调整的影响,推导出相邻列车的调整条件及方法,给出了调整后时间推移的定理,并通过实例证明用此方法可以分步进行跨列车编组顺序的调整,从而为编组站列车解体顺序与编组顺序的协调优化打下了基础。

The train classification sequence is usual to be arranged according to the departure time priority in the marshalling station. This arrangement is difficult to guarantee full-load of every departure train and the adjustment is needed at this moment. On the basis of analyzing the operation characteristics of the marshalling station, several concepts are given by the operation time standard such as the compact continuing classification, the greatest adjustment between adjoint trains and so on. The relation between the departure interval time time awaiting for departing ＆ the classification operation time and the latest permissible time for the departure train to begin classification is analyzed, and its influence on classification sequence adjustment is pointed out. The adjustment condition and method of the adjoint trains are derived out, and the time-pass theorem after adjustment is provided. It has been proved through case-study that the stepping trains classification sequence can be adjusted step by step with this method so as to lay a dependable foundation for optimized coordination of train sorting and classification sequences.
