摘要/Abstract

摘要： 我国重载铁路运输组织比较复杂，空车回送也有其特殊性。本文在借鉴已有空车调配问题研究成果的基础上，分析了重载铁路空车以列为单位回送等特点，研究了重载铁路列车组合分解作业对通过能力的影响，建立了以组合列车数量、组合时间最小化为目标的重载铁路卸车端空车回送模型，并将其转化为网络流模型，采用最小费用最大流算法进行求解。以大秦铁路空车回送为例，利用本文所建模型求解并分析计算结果，得出重载铁路重车方向以提高输送能力为主、空车方向以提高通过能力为主等相关研究结论。

关键词: 重载铁路, 空车回送, 组合列车, 最小费用最大流

Abstract: The transportation organization of heavy haul railway is complex in China, especially, the feedback of empty cars. On the basis of reference to the existing research results, and deep analysis of the characteristics of empty cars distribution of heavy haul railway, the authors construct the feedback schematic model of empty cars in unloading end of heavy haul railway. The minimum quantity of the combined trains and the time for combination is taken as the model goal and solution algorithm on the basis of minimum cost and maximum flow is formulated. Daqin railway is taken as an example and relevant conclusions of feedback scheme of empty cars of heavy haul railway, through an analysis of calculation results, are drawn.

Key words: heavy haul railway, feedback scheme of empty cars, combined train, minimum cost and maximum flow
