Abstract

Abstract: In his paper，Prof.Ye Dongyi has pointed out that the reduction approach introduced by Hu Xiaohua etc.will give wrong result in some situation.In this paper the author comes to a conclusion by analysis that the reduction approach is to keep boundary region partition unchangeable virtually.It is just different from the reduction approach given by Ye Dongyi.Then，the author analyzes the logic characteristic of boundary region partition reduction standard.

Key words: decision table, reduction standard, discernibility matrix, discernibility function

摘要： 叶东毅教授的文中指出Hu Xiaohua等学者提出的约简方法在某些情况下会给出错误的结果，论文通过分析得出该约简方法实质上保持边界域划分不变，与叶东毅教授提出的约简方法只是标准不同，而无所谓对错问题，在此基础上，分析了边界域划分约简标准的逻辑特征。

关键词: 决策表, 约简标准, 区分矩阵, 区分函数
