Abstract
This paper aims at studying optimality conditions of robust weak efficient solutions for a nonsmooth uncertain multi-objective fractional programming problem (NUMFP). The concepts of two types of generalized convex function pairs, called type-I functions and pseudo-quasi-type-I functions, are introduced in this paper for (NUMFP). Under the assumption that (NUMFP) satisfies the robust constraint qualification with respect to Clarke subdifferential, necessary optimality conditions of the robust weak efficient solution are given. Sufficient optimality conditions are obtained under pseudo-quasi-type-I generalized convexity assumption. Furthermore, we introduce the concept of robust weak saddle points to (NUMFP), and prove two theorems about robust weak saddle points. The main results in the present paper are verified by concrete examples.
