| 摘 要： | 在考虑旅客列车始发时间域和维修天窗的基础上,建立客运专线列车运行图优化模型,设计基于定序优化的客运专线列车运行图铺划方法。该方法在不断优化松弛列车运行图的过程中实现,对于当前松弛列车运行图,每次按照最小平移时间法则选择冲突进行优先化解,直至所有冲突化解为止。化解冲突时,通过构造松弛列车运行图的扩展多平行四边形和有向图,以平移作业、交换作业顺序、变更停站方案和调整列车始发时间域等方法来优化松弛列车运行图。算例分析表明,该方法能够有效地实施客运专线列车运行图的铺划。

| Abstract: | Considering the passenger train departure time domain and comprehensive window maintenance,the model for drawing the passenger train diagram for dedicated passenger lines is built and its solution method based on fixed order optimization is designed.This method resolves all conflicts by gradually optimizing the relaxation train diagram.In each optimizing process,priorities are selected to resolution of conflicts according to the rule of the minimum moving time.Then the relaxation train diagram is optimized ... |
