Abstract :
The Intuitionistic Fuzzy S-Rough sets is the intuitionistic fuzzy extension of S-Rough sets theory. It has S-Rough sets´ dynamic characteristic, as well as the membership and non-membership of Intuitionistic Fuzzy sets, thus is able to describe the transformation degree of the elements in sets more clearly and precisely. This paper defines the similitude degree and comparability of IFS-RS, and presents the calculation equation of the similitude degree based on the rough character of IFS-RS, so that the similitude degree between two IFS-RS and the precision degree of the information these two sets contain can be calculated more precisely.
