摘要
为准确判定地铁网络中各个站点的安全现状,建立基于网络层次分析法(ANP)的网络脆弱性评价模型。首先,从内部因素、外部因素以及通道因素3个维度分析网络脆弱性的内涵,并依据复杂网络理论,选取11个评价指标,构建地铁站点的网络脆弱性评价体系。其次,基于ANP法确定各层指标的权重,建立评价模型。最后,以北京地铁系统为例,对其11项指标数据进行归一化处理,依据该模型评定各个站点的网络脆弱性。计算结果表明,北京地铁网络整体安全状态良好,国贸站和七里庄站是脆弱性最高的站点。
The paper was aimed at building a network vulnerability evaluation model for subway stations based on ANP. Connotations of network vulnerability were analyzed from three dimensions including internal factors,external factors and the channel factor. An evaluation system was built established on the basis of the complex network theory. Analytic network process was used to build the evaluation model and determine the indexes＇ weights. Finally,Beijing subway system was taken as an example,the indicators were normalized,and vulnerability was evaluated for the stations. The result shows that safety situation of Beijing subway system is quite well,and that Guomao station and Qilizhuang station are typical cases of high vulnerability.
