货运列车的优化编组调度方案与实现方法

Optimize Plans of Marshalling for Grouping of Freight Train and Implementation Methods

针对2008年全国研究生数学建模竞赛C题"货运列车的编组调度问题",首先介绍了问题的背景和问题的构成,并提出了6个要解决的问题;然后概要地分析介绍了解决这6个具体问题的思想方法;接着给出了具体解决问题的实现方法、主要模型和求解思路;最后对参赛队的总体做法和存在问题情况做了较详细的分析,并就与这个题目有关的几个问题做了说明.

The problem C of the National Post-Graduate Mathematical Modeling in Contest 2008 is studied which the topic is ＂Marshalling Problem for Grouping of Freight Train＂. At first, we introduced the background and the composition of questions and put forward six questions to be solved; then briefly analyzed the thinking and methods of the six specific questions. A specific method and the main models and ideas that can solve the problems are given. Finally, we gave a detailed analysis about the team practices and the existent questions. Some of the problems relative to the topic are explained in the paper.
