不协调决策表中基于对象的近似约简

Approximate Reduction for Objects in Inconsistent Decision Tables

对不协调决策表中基于对象的近似约简问题展开研究。首先,给出近似约简的判定定理;其次,通过区分矩阵与区分函数给出约简的计算方法;最后,通过实例验证,决策表中基于对象的近似约简与整体约简相比,不仅可以获得更简洁的知识,并且在实际生活中具有较好的应用价值。

This paper studied the approximate reduction for the objects in the inconsistent decision tables.Firstly,the judgment theorems with respect to the approximate reduction were obtained.Secondly,the calculation method of the approximate reduction was given by discernibility matrices and functions.Finally,Compared to the overall reduction for a decision table,the reduction for objects in the decision table not only can get more concise knowledge,but also has good application value in real life.
