基于层次分析法的地铁站点脆弱性评价

Vulnerability Assessment of Metro Stations Based on Analytic Hierarchy Process

针对地铁网络的脆弱性分析,利用地铁拓扑结构和运营客流分布,提出一个基于层次分析法的站点脆弱性评价方法。首先建立了由干扰因子、脆弱点和脆弱元件构成的地铁网络脆弱链模型;然后从地铁拓扑结构和运营客流分布角度,对站点脆弱性进行定量分析,并应用层次分析法自动选择脆弱站点;最后通过实例验证了该评价方法的有效性。

Aiming at the vulnerability analysis of the metro network,this paper presents an analytic hierarchy process（ AHP） based method to assess the metro stations in network in light of metro network topological structure and flow distribution.Firstly,the vulnerability model of metro network is established,which is composed of the interference factor,the vulnerable point and the vulnerable component. Next,from the perspective of the metro network topological structure and flow distribution,the quantitative analysis of the vulnerability on metro stations is presented. Then,the vulnerable stations are decided automatically by the AHP. Finally,the assessment method is verified with a real city subway system.
