摘要：

为消除或减少扰动情形下列车群系统的总体延误时间,以车站延迟为延误状态,以加权平均延迟期望时间的最小化为目标,在总冗余时间一定的情况下,提出一种多车站延误情况下冗余时间再分配模型,并通过数学分析的方法求解分配模型;以京广高铁3个车站晚点数据分析验证该模型的科学性和有效性。结果表明:在利用所提模型对冗余时间再分配后,可达到最小延误状态,总延误期望减小7.26%。该方法在一定程度上能够减少列车群晚点时间,具备一定的科学性和有效性。

Abstract:

In order to eliminate or reduce overall delay time of train group system in disturbed situations, a redundant time redistribution model for delays at multiple stations was proposed given fixed overall redundant time, with station delay as delay state and minimum expected average weighted delay time as an objective. Then, the model was solved by mathematical analysis method. Finally, its scientificity and effectiveness were verified through analysis on delay data of three stations on Beijing-Guangzhou high-speed railway. The results show that by reallocating redundant time, the proposed model can achieve minimum delay with total expected delay being reduced by 7.26%. It is proved to be scientific and effective as it reduces train group delays to a certain extent.
