The Comparison of Fuzzy Set and Rough Set

Feng Yuan 1 Zhang Bin 2 (1.Department of Mathematics, Taiyuan Teachers College, Taiyuan 030012; 2.Department of Information Technology, Shanxi Commerical Bank, Taiyuan 030002,China)  
Much effort has been devoted recently to studying the problem of knowledge acquisition under uncertainty. Uncertainty arises in many different situations. It can be caused by ambiguity in the terms used to describe a specific situation, skepticism of rules used to describe a course of action, or missing and/ or erroneous data. To deal with uncertainty,the theory of fuzzy set and rough set are powerful tool. These two theories have some connections and differences,so combining fuzzy set and rough set in a fruitful way can deal with more problem.
