基于智能化应用的列车运行调整模型

Train Operation Adjustment Model Based on Intelligent Application

基于列车运行调整理论研究现状,在分析现有研究局限的基础上,提出建立列车运行自动调整模型应考虑的4个关键问题:部分非运行图相关信息、动车组接续、交叉进路抵触及股道-线别连通性。基于这些关键问题构造10个约束条件,结合智能CTC系统技术标准,以提升旅客满意度为导向,依据旅客行程信息和多目标优化的思想,建立将列车运行调整对旅客出行实际影响最小化的目标函数,构建可满足智能化应用的列车运行自动调整规划模型,将其引入开发中的智能CTC系统,并通过京张高铁3个列车运行调整实际场景进行验证。结果表明:模型能够准确处理各种场景下的列车运行偏离,生成切实可用的列车运行阶段计划;生成的计划能有效消解列车晚点造成的交叉进路抵触、股道运用冲突及动车组接续等冲突,在兼顾旅客换乘考虑的同时,缩小列车晚点波及范围,控制晚点传播。

Based on the current research status of train operation adjustment theory and the analysis of existing research limitations,four key issues are proposed to be considered in establishing an automatic train operation adjustment model,such as some issues not related to train working diagram,EMU connection,crossing route conflict and track-line connectivity.Ten constraints are constructed based on these key issues proposed.Combined with the technical standards of intelligent CTC system,guided by the promotion of passenger satisfaction,according to passenger travel information and the idea of multi-objective optimization,an objective function is built to minimize the actual impact of train operation adjustment on passenger travel,and an automatic train operation adjustment planning model caters for intelligent application is constructed.This model is introduced into the development of intelligent CTC system and verified by three actual scenarios of train operation adjustment of Beijing-Zhangjiakou high-speed railway.Results show that the model can accurately deal with the train operation deviation in various scenarios,and generate practical and available train operation stage plans.The train operation plans generated can effectively eliminate the conflicts caused by train delay,such as crossing route,track utilization and EMU connection.At the same time,the plans can reduce the spread range of train delay and control delay spread while taking passenger transfer into account.
