Abstract: The generalized decision distribution function of objective random information system is given. The μ-reduction based on objects in inconsistent objective random information systems under the equivalent relation and dominance- equivalent relation are proposed. Meanwhile some properties, the judgment theorem and calculation approach of μ-reduction are obtained. Finally, a numerical example is used to illustrate the validity of this calculation method.

Key words: inconsistent objective random information system, equivalent relation, dominance-equivalent relation, μ-reduction
