基于TOPSIS熵权法的高速铁路动车组运用水平评价方法研究
Research on the Utilization Level Evaluation Method of High Speed Railway EMU Based on TOPSIS and Entropy Weight Method
摘要
Abstract
With the increasing scale of high speed railway networks,the inventory of electric multiple units(EMUs)and the demand for passenger travel continue to increase,which poses higher requirements for the operation level of EMUs.To rationally optimize the EMU routing schemes and improve the EMU efficiency,this paper aims at the problem of evaluating the utilization level of high speed railway EMU.By using the analytic hierarchy process,the evaluation index system of the utilization level of high speed railway EMU was established,which includes three first-level indexes and nine second-level indexes by taking the utilization efficiency of EMU,the utilization evenness of EMU and the utilization reasonableness of EMU.Moreover,the qualitative description of each index was translated into mathematical expressions,and the comprehensive evaluation method of the utilization level of high speed railway EMU was designed based on the TOPSIS theory and the Entropy Weight method.The EMU routing schemes of a high speed railway line in the third quarter of 2022 were taken as an example to verify the evaluation method.The results show that the proposed TOPSIS Entropy Weight method effectively solves the problem of EMU utilization level evaluation,providing a scientific basis for the comparison and selection of EMU routing schemes.This is of great significance for improving the efficiency of transport capacity resource organization and the benefits of railway operation.关键词
