为降低城市地铁网络系统(UMNS)运行的物理脆弱性,在一般系统脆弱性分析的基础上,从模型构建、适用性分析和失效模式(FM)3个方面构建UMNS物理脆弱性分析技术方案。在深入分析UMNS物理系统特征的基础上,应用复杂网络理论构建UMNS的无权有向图模型,并借助于Pajek和R软件进行实证分析。结果表明:基于复杂网络理论的UMNS物理脆弱性分析是可行的;仿真结果能够反映UMNS的物理脆弱性与其物理拓扑结构的关系,并能用来定量分析UMNS的物理脆弱性;通过算例分析验证模型,能够找出城市地铁物理系统中的脆弱源。
In order to reduce the physical vulnerability of the UMTS system, based on the analysis of the general system vulnerability, the UMNS physical vulnerability analysis technology is constructed from the aspects of model construction, applicability analysis and failure mode (FM). Based on the in-depth analysis of the characteristics of UMNS physical system, this paper uses the theory of complex networks to construct the UDDI model of UMNS, and uses Pajek and R software to make empirical analysis. The results show that it is feasible to analyze the physical vulnerability of UMNS based on complex network theory. The simulation results can reflect the relationship between the physical vulnerability of UMNS and its physical topology and can be used to quantitatively analyze the physical vulnerability of UMNS. Model that identifies the source of weakness in the physical system of urban metros.
