In this paper, we introduce a more general approach to the fuzzification of fuzzy concavity. More specifically, the degree of L , M -fuzzy concavity is introduced and characterized as a generalization of L -concave structure and L , M -fuzzy concave structure. Based on that, the degree of L , M -fuzzy concavity preserving and L , M -fuzzy concave-to-concave of a function are defined. Some properties and relationships between the degree of L , M -fuzzy concavity preserving and L , M -fuzzy concave-to-concave functions are discussed.
