基于区域路网整体运输效能的列车运行图质量评价

Evaluation Method of Train Diagram Quality Based on Overall Transportation Potency of Regional Rail Network

摘要:

区域路网中线路和区段数量多、运力资源组成复杂、客货运输需求差异大，区域路网列车运行图质量直接关系到铁路网整体运输效能。基于列车运行图在运输能力、运营效益和服务质量三方面的运输效能表现，从不同版本运行图质量变化和单个版本运行图质量检验2个需求点出发，构建了区域路网列车运行图整体运输效能5级评价指标体系，提出了融合灰色关联度法、横向拉开档次法的版本对比评价方法，以及基于K-MEANS++聚类和改进理想解法（TOPSIS）的区段对比评价方法。以上海铁路局3个不同版本的全局路网列车运行图为例，版本对比评价结果显示0620图编制质量最佳，且在区段对比评价中表现良好。本文方法实现区域路网列车运行图多维度分层次评价，评价结果可为运行图编制调整提供决策依据。

Abstract:

The regional rail network is characterized by numerous lines and sections， complex composition of transportation capacity resources and great differences in passenger and freight demand. The quality of train diagrams is directly related to the overall transportation potency of the regional rail network. Based on potency in terms of capacity， efficiency and quality， a five-level evaluation index system is built. For version difference analysis， a version comparison evaluation method is developed， integrating the gray relevancy and the horizontal pull-off grade methods. For quality inspection， a section comparison evaluation method is developed based on the K-MEANS++ and the improved TOPSIS. Case studies on three different versions of the railway network train diagram in Shanghai Railway Group show the 0620 version is the best in version comparison and performs well in section comparison. The evaluation results are multi-dimensional and hierarchical， and provide a decision-making basis for the preparation and adjustment of the train diagram.
