Optimization Analysis of Urban Railway Line Selection Based on Multi-Objective Comprehensive Evaluation System
[Purposes]Based on the multi-objective comprehensive evaluation system,the optimization analysis of urban railway line selection is carried out to solve the problem of railway line selection in complex urban environment.[Methods]The influence of multi-source factors such as interference degree of existing lines,environmental impact,economic feasibility,land acquisition and demolition on railway line selection is comprehensively analyzed,and a hierarchical structure model with clear index system is further constructed.In order to overcome the influence of subjective factors on the weight and the uncer-tainty and randomness of multi-source factors,the entropy weight method is integrated into the Analytic Hierarchy Process(AHP)to construct a multi-objective comprehensive evaluation system for railway line selection,and then optimizing the design of railway line selection in a city.[Findings]The research shows that the use of multi-objective comprehensive evaluation system for railway route selection optimi-zation can avoid the influence of subjectivity on decision-making results and the strict requirements of quantitative analysis on index data.[Conclusions]The research method improves the decision-making accuracy to a certain extent,and is an effective method to solve the multi-objective decision-making problem of railway line selection.
