铁路编组站列车出发车数的确定是一个具有较大实际意义的困难问题。文献〔1〕给出了给定列车满轴车数条件下，编组站出发列车运行线选择和出发车流确定的网络流优化模型及算法。但在铁路实际运输工作中，合理的满轴车数往往允许存在10％～20％的差异。如何考虑这种满轴车数在一定界域内取值优化的列车出发计划，本文给出这个问题的两种处理方法。
The determination of the number of starting marshals for the railway marshalling train is a difficult issue of great practical significance. Literature [1] gives the network flow optimization model and algorithm for determining the line selection of starting train and the starting flow of a given train under the condition of full train number of train. However, in the actual work of railway transportation, the reasonable number of full-axis vehicles often allows the difference of 10% ~ 20%. How to consider this kind of train departure plan that the number of full cars in a certain threshold value is optimized, this paper gives two solutions to this problem.
