In stead of intuitionistic fuzzy covering, a new intuitionistic fuzzy binary relation is proposed using a set in an intuitionistic fuzzy covering, and correspondingly the intuitionistic fuzzy approximation space is obtained. Then a novel discernibility matrix is defined which is based on the intuitionistic fuzzy binary relation we defined. And then reductions of intuitionistic fuzzy covering information systems are studied by remaining the intuitionistic fuzzy binary relation unchanged.
