Attribute Reduction and Rule Acquisition in Incomplete and Inconsistent Ordered Decision Systems

针对不完备不协调序决策系统,提出了广义优势决策函数的概念,给出了基于广义优势决策函数的区分矩阵属性约简算法,并获得了提取序决策规则的方法。最后,实例说明了所提出算法的有效性。

The notion of a generalized dominance decision function is defined in an incomplete and inconsistent ordered decision system,and its discernibility matrix is proposed to design an attribute reduction algorithm. Then a new approach of rule acquisition is obtained in an incomplete and inconsistent ordered decision system by generalized dominance decision function. Finally, a real example is used to demonstrate the effectiveness of the proposed algorithm.
