Abstract :
Recently, most works of interval valued fuzzy rough sets (IVFRSs) have been focused on the membership intervals representation. Less work on granular representation of IVFRSs was done. In this paper the interval valued fuzzy granular representation of IVFRSs is presented. That is to say, the granular structure is studied in interval-valued fuzzy approximation space.
