基于不确定型AHP的网络生存能力模糊综合评估

Fuzzy Comprehensive Assessment in Network Survivability Based on the Uncertain AHP

对网络系统的生存能力进行量化评估,有助于对不同系统以及同一系统在不同环境下的可生存性做出准确的评价和比较。本文提出了将不确定型AHP和模糊综合评估技术相结合的方法,建立网络生存能力评估模型。利用不确定型AHP学习得到系统中各因素权重,然后依据隶属度函数对指标评语进行模糊化处理并构建模糊矩阵,再应用模糊综合评估技术得到网络生存能力的综合量化评估结果。通过实例分析,表明应用该方法对网络生存能力进行评估是有效和可行的。

Quantifying survivability of the network system helps same system in different environments. This paper puts forward to evaluate it exactly for either different systems or the a new method that combines uncertain AHP with fuzzy comprehensive assessment technology to build an assessment model of network survivability. Using uncertain AHP acquire the weight value of each factor,and then the comment scores are fuzzed through membership function of fuzzy theory and construct fuzzy matrix. Finally we will gained the quantities evaluating result by adopting fuzzy comprehensire assessment technology. An instance is given to prove the validity and feasibility of using the method in network survivability assessment.
