Abstract
This paper first introduces a crisp classification relation based on an intuitionistic fuzzy set in a nonempty set. A covering for the universe of discourse is induced by this classification, and the connection between classification relation and the covering is discussed. Moreover, a pair of upper and lower approximations is defined according to the intuitionistic fuzzy classification, and some properties are investigated.
