This paper shows three aspects as follow : 1. an algorithm of attribute reduction based on discernibility matrix - - - - ardm is presented. through analyzing to the algorithm of attribute reduction based on discernibility matrix, the facts that affect time efficiency are found, and the absorptivity in the proposition calculation is used to the process of constructing the discernibility matrix, then the effectless repeated elements are deleted, accordingly the efficiency of attribute reduction is improved
本文的主要研究成果有以下三個方面： 1 .提出了一種基於區分矩陣的屬性約簡演算法ardm通過對基於區分矩陣的屬性約簡演算法進行分析，找出影響時間效率的因素並將命題演算中的吸收率用於構造區分矩陣的過程中，從而去掉了在區分函數中不起作用的「重復」元素，提高了屬性約簡的效率。
