基于AHP-DEMATEL的高铁枢纽换乘效率关键因素研究

为了找出影响高铁枢纽换乘效率关键因素,科学合理高铁枢纽布局,提出一种基于AHPDEMATEL组合评价方法。以高铁枢纽为评价对象,通过构建具有层次结构的评价指标体系,采用层次分析法(AHP)确定指标初始权重,决策与试验评价实验室法(DEMATEL)求得各评价指标影响度、被影响度、中心度,从而确定各指标综合影响度。研究结果表明:其他交通衔接性、通道便捷性、设施供给度、枢纽组织有序度、停车场供需比、平均换乘时间、平均换乘距离、单位时间换乘量、绕行系数是影响高铁枢纽换乘效率的关键因素。

Research on Key Factors of Transfer Efficiency of High-Speed Railway Hub Based on AHP-DEMATEL

In order to find out the key factors influencing the transfer efficiency of the high-speed rail hub, scientific and reasonable layout of the high-speed rail hub, a combined evaluation method based on AHPDEMATEL is proposed. Taking the high-speed rail hub as the evaluation object, by establishing a hierarchical evaluation index system, AHP is used to determine the initial weight of the index, and the decision and test evaluation laboratory method(DEMATEL) is used to obtain the degree of impact and the degree of impact of each evaluation index. Centrality, so as to determine the comprehensive impact of each indicator. The results of the study show that: other transport connections, accessibility of channels, degree of facility supply, order of hub organization, supply-demand ratio of parking lot, average transfer time, average transfer time, average transfer distance, transfer volume per unit time, roundabout Line factor is a key factor affecting the transfer efficiency of high-speed rail hub.
