摘要： 对粗糙集(Rough Set)理论中属性约简和值约简算法进行了研究，提出了一种新的基于粗糙集的值约简算法。实验表明，该算法所得结果比目前通用的基于粗糙集的值约简算法更简化和有效，它可以应用到各种与值约简相关的实际问题中。

Abstract: This paper discusses the approaches for attribute reduction and value reduction based on rough set theory. Following that it puts forward a new algorithm for value reduction The experimental and performance studies show that the new algorithm has reached a better and briefer result than the algorithm being widely used at present. It can be applied to solve various practical problems on value reduction.
