Abstract:

摘要: 利用集族上的等价关系,引入不协调目标信息系统中基于对象子集的μ-约简的概念,得到了μ-约简的一些性质和判定定理及相应的可辨识矩阵,同时提出不协调目标信息系统中基于对象子集的μ-约简的计算方法,用实例验证了该方法的有效性。
Abstract: The μ-reduction based on the subsets of the objects in inconsistent information systems is given by the equivalence relation on the set group. Also, some properties of μ-reduction,the judgement theorem and corresponding discernibility matrix with respect to the μ-reduction are obtained. And an approach to calculate μ-reduction is provided. A numerical example is used to illustrate the validity of this method
