Abstract :
The notion of equivalence in fuzzy concepts based on the pinned-flag of fuzzy set is introduced, and then the equivalence class of fuzzy concept lattice is defined. Some propositions of them are proposed. Furthermore, the refinement in fuzzy concepts is defined according to the covering of a set, and the relation between the refinement and the equivalence of fuzzy concepts is discussed.
