摘要：
Aiming at the problem of evaluating network system survivability efficiently, the construction of index systems, weighting of indexes and synthetic evaluation method are studied. A constructing method of the network survivability index system by way of mechanism-associating is proposed, the hierarchy index system is constructed from the angle of survivability's four important attributes. A new combinatorial weighting method is given based on the index system. The subjective weight is calculated using analytic hierarchy process. The objective weights using rough entropy is calculated. The concept and calculating method of the associated weight are given. The three weights are combined into combinatorial weight using a minimum object optimization function. The fuzzy synthetic evaluation model based on cloud membership is established. The primary determinate membership function is replaced by cloud membership. The simulation results show that this evaluation method could evaluate the network system survivability accurately and efficiently.
