基于DEA模型的动车组列车运行线效率评价
Evaluation of Electric Multiple Unit Train Path Efficiency Based on DEA Model
摘要
Abstract
The train path is the basic element of the train working diagram,and the train path efficiency is the evaluation index reflecting the relative quality of the train working diagram.Train path efficiency can be simplified as the ratio of technical index to invested transportation resource from a system perspective.This paper considered that lower-speed trains had a lower efficiency when giving the way to higher-speed trains.Therefore,it is difficult to use one set of standards to evaluate the efficiency of various types of train paths objectively and effectively.In order to reflect the interaction between the system and elements,as well as the interaction among elements,this paper studied the busyness level of sections and stations and the cost of train overtaking and built a train path efficiency calculation model.The paper used the train working diagram data for a quarter as an example for verification,and the results show that the efficiency gap between lower-speed trains and higher-speed trains is narrowed,which makes the efficiency of trains with different speed levels comparable.The paper also analyzed the train working diagram data for a quarter,and the results show that the comprehensive efficiency of the train that uses high speed operating scales is higher than other train types.Finally,targeted suggestions were provided to improve the train path efficiency based on the projection of data envelopment analysis(DEA).关键词
