摘　　要：对Rough集的属性约简进行分析,特别针对不一致决策表,提出一种新的约简算法。算法通过等价类消除决策表不一致性,然后利用传统算法进行约简,并用实例证明算法可行性。Attribute reduction of Rough set was analyzed, and a new reduction algorithm was proposed particularly for inconsistent decision table. First, algorithm eliminated the inconsistency of the decision table based on the equivalence class. Then the traditional algorithms were used for reduction, and examples proved the feasibility of the algorithms.
