摘　　要：定义了一类ρ不变凸函数,研究了不可微多目标分式规划问题,得出了涉及这类函数的多目标分式规划的最优性充分条件,在更弱的凸性下,获得一些重要的结果。A class of ρ invex function was defined, nondifferentiable multi -objective fractional programming was researched, the sufficient condition of optimality involved this kind of function was obtained under weeker convexity, many important conclusions were extended.

关 键 词：ρ不变凸函数 多目标分式规划 最优性
