| 摘 要： | 提出了一种基于覆盖粗糙集理论，利用最大一致块技术进行不完备信息系统约简的方法。在证明利用最大一致块技术生成的相容类构成论域的最简覆盖基础上，利用覆盖粗糙集理论对已利用最大一致块技术进行属性约简的信息系统进行属性值约简，并提出一种新的约简算法。

| Abstract: | Proposed a reduet method of an incomplete information system based on covering rough set theory and maximal consistent block technique. On the base of minimal covering constructed the tolerance classes from the maximal consistent block technique, carried the attribute value reduct through the covering rough set theory on the system that has been reduced in attributes by the maximal consistent block technique, and proposed a new reduct algorithm. |

| Keywords: | incomplete information system reduct covering rough set maximal consistent block rough set |
