路网条件下旅客列车运行方案图协调优化理论与方法

With the high-speed railways being in service gradually in our country, the complex passenger railway network composed of the high-speed and existing railway has been formed rapidly. Therefore, it has been becoming more and more difficult to make the global train diagram and it is urgent to make full research on train operation diagram planning intelligently. The passenger train timetable, the core of the passenger train operation diagrams, mainly deals with the overall layout of the passenger train running tracks, the quality of which will affect directly on the train diagram’s quality. Aimed at the new features of passenger transport organization based on the network composed of the high-speed and existing railways, the optimization method of passenger train path linkage is studied in depth. According to the coordination mechanism of the station capacity and the line capacity which is revealed already, the optimization method of the passenger train paths based on the coordination of station and line is proposed. Furthermore, the optimization model of passenger train operation schema diagram under the railway-network condition is set up. Considering the model’s characteristics, an efficient heuristic algorithm based on the node important degree of passenger transportation is designed, which is used to solve the model. Also, an example is given to validate the model by simulation methods. A set of optimization theories and methods of the passenger train schema diagrams with the network composed of the high-speed and existing railways is constructed to improve the system of train working diagram in the end, which can supply the theoretical support for improving the automatic and intelligent level of transportation plans greatly.

随着高速铁路线路的相继开通运营，我国铁路已快速形成由高速铁路和普速铁路贯通运营的复杂客运网络，铁路列车运行图编制工作的难度越来越大，列车运行图编制的智能化亟待深入研究。其中，旅客列车运行方案图主要是解决旅客列车运行线整体布局问题，是旅客列车运行图的骨架和核心，直接影响列车运行图质量的优劣。项目拟针对高速铁路与普速铁路贯通成网条件下旅客运输组织的新特点，揭示高速铁路与普速铁路旅客列车运行线协调机理，提出基于车站与线路能力协调的旅客列车运行线优化方法。在此基础上，构建路网条件下旅客列车运行方案图优化模型。依据模型的特点，提出基于客运节点重要度的高效启发式算法,并通过仿真方法，进行实例验证，建立一套路网条件下旅客列车运行方案图优化理论与方法，并将相关研究成果应用到铁路列车运行图编制系统，提高铁路运输计划编制智能化水平。

旅客列车运行方案图的编制重点在于解决列车运行图的整体布局问题，它是铁路列车运行图的骨架和核心，在很大程度上决定了列车运行图的质量水平。但一直以来，对旅客列车运行方案图编制质量起着决定性作用的列车运行方案主要是人工凭经验通过反复试探得到的，列车运行方案图编制的智能化亟待深入研究。.目前，项目申请书中所列主要研究内容都已经完成。项目通过对高速铁路车站通过能力计算方法和天窗设置方案与合理开行时间域等关键问题进行研究的基础上，深入研究并提出了基于车站能力的旅客列车运行方案优化理论与方法、跨线旅客列车运行方案优化理论与方法、高速铁路列车运行方案图优化方法理论与方法、新旧交替列车运行方案图编制优化理论与方法以及旅客列车运行方案图与机车周转图（动车组交路）协调优化方法，形成了路网条件下旅客列车运行方案图协调优化理论与方法。在相关理论研究成果的基础上，研发升级了铁路列车运行图编制系统。.项目相关研究成果出版了专著《路网条件下铁路列车运行方案图优化理论与方法》，建立了一套路网条件下旅客列车运行方案图协调优化理论与方法。基于项目的理论成果，研发升级了铁路列车运行图编制系统，该系统通过了中国铁路总公司运输局的技术评审，在中国铁路总公司和各铁路局集团有限公司编图工作中得到推广和应用，并获中国铁道学会铁道科技奖一等奖。项目研究相关成果共正式发表期刊和会议论文53篇，其中SCI检索论文7篇，SCI和SSCI双检索论文4篇，交通运输顶级期刊Transportation Research Part B论文1篇，EI检索论文26篇。培养博士研究生2名，硕士研究生3名。项目负责人晋升副教授，项目成员1人晋升高级实验师，项目成员获第十三届詹天佑铁道科学技术成就奖1人。相关研究成果申请受理国家发明专利6项，获中国铁道学会铁道科技奖一等奖2项、三等奖1项。目前为止，项目研究成果已经达到了预期的研究目标，项目为路网条件下铁路运营组织提供科学的理论依据和技术支持，有助于提高我国铁路运营组织水平。
