On Mond-Weir-Type Robust Duality for a Class of Uncertain Fractional Optimization Problems

This article is focused on the investigation of Mond-Weir-type robust duality for a class of semi-infinite multi-objective fractional optimization with uncertainty in the constraint functions. We first establish a Mond-Weir-type robust dual problem for this fractional optimization problem. Then, by combining a new robust-type subdifferential constraint qualification condition and a generalized convex-inclusion assumption, we present robust epsilon-quasi-weak and strong duality properties between this uncertain fractional optimization and its uncertain Mond-Weir-type robust dual problem. Moreover, we also investigate robust epsilon-quasi converse-like duality properties between them.
