Comprehensive Evaluation Method for Network Survivability under Complex Environment
复杂环境下网络抗毁性综合评估方法

In order to evaluate the network survivability quantificationally and objectively in complex environment, a muti-objects network survivability evaluation method was proposed. The concept of environment parameter set based on PSO was introduced,which was used to show the indexes' weight and the different rectuirements for network surviva- bility index in different environments. And from the view of node, considering the itegration of the network robust, a- vailability,adaptation and cost,an algorithm which can reflecte the general network survivability performance in diffe- rent environment was proposed. The problems of the existing methods such as subjective, non-quantification, poor adap- tation, were solved. I}he method was verified through simulation.
