摘要: 传统的AHP方法由于判断值受人为影响因素太大,导致在衡量多因素权重时常常出现结果不一致,影响了结论的准确性和评估结果的可信任性。建立了基于“网络-主机-服务-评估因子”的层次风险评估模型,利用层次化的计算模型评估网络的风险等级。从给出的区间判断矩阵入手,将区间判断矩阵一致逼近到一般的数字判断矩阵,提出一种自动修正判断矩阵的层次分析法,得到各层元素的近似权重。通过实例验证,表明该方法能精确地、自动化量化实时风险势态状况。

Abstract: Because the judgment of traditional AHP is deeply subjected to the artificial factor,results don’t consist with each other while scaling multifactor weight,influencing the accuracy of the conclusion and the dependability of the analyzing results.This paper builds up a hierarchy risk evaluation model based on ‘network-host-service-evaluation factor’,using the hierarchized calculation model to evaluate the risk grade of the network.Considering the given interval judgment matrix,firstly,make it consistently approximate a digital judgment matrix,then bring an analytic hierarchy process of adjusting judgment matrix forward,finally,gain approximate weight of every layer’s elements.Experiments and examples validate that this method can quantize the real-time risk condition accurately and automatically.

Key words: risk evaluation, analytic hierarchy process, interval judgment matrix, adjusting judgment matrix
