1、越行许可条件下的高速铁路列车运行图研究在模型建立完毕后，对模型中的参数给出了相应的确定办法。（4）在完成模型建立后，需要针对模型建立有效的求解算法。因此，针对模型设计了基于模拟退火的全局优化启发式算法，算法包括两部分：一、由于存在不同速度等级的列车，因此，可能会出现列车运行线的冲突，为此，本文先设计了列车运行图的冲突消解策略。二、将求解列车运行线冲突消解策略嵌套在模拟退火算法中，设计了基于模拟退火算法的全局优化启发式算法。关键词：高速铁路；运行图；列车越行；运行线冲突；启发式算法论文类型：应用研究-II-万方数据兰州交通大学硕士学位论文AbstractTraindiagramisnoto
