摘　　要：研究冗余时间利用效率,分析冗余时间与晚点恢复之间的关系,对高速铁路列车运行图优化具有重要意义。本文基于武广高速铁路列车运行的实绩,建立基于晚点恢复效率最大的高速铁路冗余时间优化模型。首先分析武广高铁下行计划运行图,提取相关区间、车站冗余时间利用情况,分析各站到发晚点情况,运用岭回归模型,建立基于列车晚点恢复效率最大化的冗余时间布局模型,并用遗传算法求解,优化后晚点恢复效率平均提高了26%。The study of buffer time utilization efficiency and the analysis of the relationship between buffer time and delay recovery are of great significance in the optimization of high-speed railway train operation diagrams.This paper establishes a high-speed railway buffer time optimization model based on the maximum efficiency of delay recovery based on the actual performance of train operation of the Wuhan-Guangzhou high-speed railway.Firstly,we analyze the downstream planning operation diagram of Wu-Guangdong high-speed railway.Then,we extract the relevant intervals and stations’buffer room utilization to analyze the arrival and departure delay situation of each station.Finally,we apply the ridge regression model to establish the buffer time layout model based on maximizing the delay recovery efficiency of trains,and solve the model with a genetic algorithm.The delay recovery efficiency is improved by 26%on average after optimization.
