Vulnerability Assessment Model for Network Critical Infrastructure & Its Application
YI Li-xin · Zhongguo anquan kexue xuebao · 2010
Based on the network graph theory,this paper builds a mathematical programming model and uses the model to assess the vulnerability of network critical infrastructure.ArcGIS is used to number all of arcs and nodes in the network and expresses the topology of the network in digital form.Mathematical programming software is used to solve the mathematical programming model,and the vulnerability components(arcs or nodes) of network critical infrastructure are obtained.The results show that the destruction of these components will maximize the vulnerability of network critical infrastructure,and so it is very important to protect these components in priority.Finally,the model is applied to assessing the vulnerability of the traffic network system of Jing-jin-ji Expressway,and the vulnerability components for the network system are gained.
