粗糙集理论与其它不确定理论的比较分析

Relative analysis on rough set theory and other uncertain theories

粗糙集理论作为一门新兴的不确定理论正越来越受到人们的关注.在介绍粗糙集理论基本内容的基础上,对粗糙集理论与模糊理论、随机理论、灰色理论等其它不确定理论的差异性进行了分析,同时讨论了它们之间的互补性问题并构建了相应的互补模型,最后,指出了粗糙集理论对于进一步丰富和完善不确定理论体系的重要性.

As a new uncertainty theory, the rough set theory is engaging more and more people's attention. The basic concepts of rough set are introduced. On the base of this, the difference between the rough theory and other uncertain theories such as fuzzy theory,random theory and grey theory is analyzed.At the same time,the complementary problems are discussed and the complementary models are established.At last,the importance of the rough theory on making the indefinite theory perfect is pointed out.
