Abstract: Inconsistent decision formal context and approximate function on inconsistent decision formal context are defined. This paper gives some results of approximate consistent sets, approximate discernibility matrices and approximate reduction method. An example is provided for verifying the feasibility of the approximate reduction method.

Key words: inconsistent decision formal context, attribute reduction, approximation consistent set

摘要: 主要对不协调决策形式背景进行了定义,给出了近似函数和近似协调集的判定定理。给出近似可辨识矩阵和近似约简的方法,通过实例验证了该方法的可行性。
