%X 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.
