中文摘要:针对无线网络脆弱性评价指标体系中影响因素众多、层次结构复杂且指标间存在相关性的问题,提出了一种基于知识约简算法的脆弱性指标体系构建方法.首先,初步建立无线网络脆弱性评价的指标体系,在此基础上构造脆弱性评价决策表;其次,运用知识约简算法对决策表进行简化,其中非核指标的重要性排序采用特征向量法进行确定,该方法以保证评价结果的准确性为前提,较AHP权重判断法更具客观性;最后,将该方法和AHP权重判断法进行了分析比较,说明了其有效性.

Target system construction of vulnerability evaluation for wireless network based on knowledge reduction
Abstract:Aspects such as multiple influencing factors,complicated hierarchical structure,and relation between indicators perplexed the vulnerability evaluation target system for wireless network.This paper proposes a method to construct target system of vulnerability evaluation based on knowledge reduction.Firstly,a primary target system of vulnerability evaluation for wireless network is established,hence the decision table of vulnerability evaluation is constructed.Secondly,the knowledge reduction is employed to simplify the decision table,and arithmetic of character vector is used to sort the significance of non-core targets.Premised on high accuracy of evaluation result,this proposed method is more objective than AHP weight judgment method.Finally,this knowledge reduction based method is comparatively analyzed with AHP weight judgment method to validate its feasibility.
