【摘要】：针对网络系统可生存性的有效评估问题,对指标体系的构建,指标赋权及综合评估方法进行了研究。提出了一种机制关联的网络可生存性指标体系构建方法,从可生存性的4个重要属性角度构建了层次化的指标体系,依据该指标体系提出了一种新的组合赋权方法,由层次分析法计算主观权重,粗糙熵方法计算客观权重,并给出了关联权重的概念和计算方法,构建离差最小化目标优化函数将3种权重联合得到组合权重,建立了基于隶属云的模糊综合评估模型,将隶属云替代原来的确定性隶属度函数。仿真结果表明,该评估方法可对网络系统可生存性进行准确有效的评估。
[Abstract]:Aiming at the effective evaluation of the survivability of network system, this paper studies the construction of index system, index weighting and comprehensive evaluation method. In this paper, a method of constructing network survivability index system based on mechanism correlation is proposed, and a hierarchical index system is constructed from four important attributes of survivability. According to this index system, a new combined weighting method is proposed. The subjective weight is calculated by analytic hierarchy process and objective weight is calculated by rough entropy method. The concept and calculation method of correlation weight are given, and combined weights are obtained by constructing objective optimization function of deviation minimization. The fuzzy comprehensive evaluation model based on membership cloud is established, and the membership cloud is replaced by the original deterministic membership function. Simulation results show that the proposed method can accurately and effectively evaluate the survivability of network systems.
