| Abstract: | This paper introduces some basic concepts of Rough Sets,illustrates the relation between Rough Sets and information system,constructs a distance function based on Rough approximation,and also transforms the values of attributes into the interval values. In addition,the decision system of diagnosis and treatment in Chinese medical is introduced. At last,the prospects of Rough Sets is discussed. |
