将直觉模糊和区间直觉模糊集(数)的距离测度引入直觉模糊信息系统和区间直觉模糊信息系统,建立基于距离的粗糙集模型,并给出该模型两种约简-上下近似约简的定义.通过构造分辨函数,设计距离直觉模糊粗糙模型的知识约简及规则提取算法.最后将距离直觉模糊粗糙模型应用于信息系统安全审计风险判断,这不仅可为从直觉模糊和区间直觉模糊信息系统中获取知识提供一种粗糙集方法,而且还为信息系统安全审计风险的有效判断提供决策支持.
The distance measure of intuitionistic fuzzy interval intuitionistic fuzzy set (number) is introduced into the intuitionistic fuzzy information system and interval intuitionistic fuzzy information system to establish the distance-based rough set model and the definition of two reduction-top-down approximations of the model This paper designs knowledge reduction and rule extraction algorithm of distance-distance fuzzy inference model by constructing resolution function.Finally, distance-aware fuzzy rough model is applied to the risk judgment of information system security auditing, which not only can be used in the field of intuitionistic fuzzy and interval intuitionistic fuzzy information system Access to knowledge to provide a rough set of methods, but also provide effective decision-making support for the effective judgments of information security audit risk.
