【Abstract】 Concavo-convex fuzzy set is conceived by combining the concepts of convex and concave fuzzy sets.Based on the concept of concavo-convex fuzzy set and its properties in one dimensional space,the monotonicity of the concavo-convex fuzzy set is defined.Upon corresponding concepts and lemmas,the already obtained properties are generalized in R1to Rn by analysis method.更多还原
