摘　　要：给出了预不变凸模糊数值函数方向导数的定义,在一种新序意义下讨论了模糊数学规划问题的严格局部最优解、全局最优解与方向导数的关系.This paper defines the directional derivative of pre-invex fuzzy-valued function and based on the new ordering of fuzzy numbers,disscuss fuzzy mathematical programming problems of strict local optimal solution and the relationship between global optimal solutions and directional derivative.

关 键 词：模糊数 预不变凸性 模糊优化
