针对不协调决策信息系统中的不协调决策规则，定义了不协调决策规则对。对于属性或对象较多的不协调决策表，用辨识矩阵提取不协调决策规则对较为繁琐。首先利用包含度筛选含有不协调决策规则对的等价类，然后由辨识矩阵提取不协调决策规则对，并计算其数目。也可以根据广义决策分布函数的分量直接计算不协调决策规则对的数目。进而计算出不协调决策表的不协调度。最后研究约简前后不协调决策表的不协调度之间的关系。
針對不協調決策信息繫統中的不協調決策規則，定義瞭不協調決策規則對。對于屬性或對象較多的不協調決策錶，用辨識矩陣提取不協調決策規則對較為繁瑣。首先利用包含度篩選含有不協調決策規則對的等價類，然後由辨識矩陣提取不協調決策規則對，併計算其數目。也可以根據廣義決策分佈函數的分量直接計算不協調決策規則對的數目。進而計算齣不協調決策錶的不協調度。最後研究約簡前後不協調決策錶的不協調度之間的關繫。

The definition of inconsistent decision rule pairs is proposed in an inconsistent decision information system with inconsistent decision rules.It is relatively complicated by using discernibility matrix to extract inconsistent decision rule pairs from inconsistent decision table with many objects or attributes.Inclusion degree is used to screen the equiva-lence classes which can produce inconsistent decision rule pairs,then discernibility matrix is employed to extract incon-sistent decision rule pairs,thus calculating the number.The number can be also calculated by the component of general-ized decision function directly.And then the inconsistent degree of an inconsistent decision table is computed.Finally, the relationship of inconsistent degree between original inconsistent decision table and reduced inconsistent decision table is studied.
