New generation duality models in discrete minmax fractional programming on sounivexities

Abstract

In this research, first four new general higher-order parametric duality models for a discrete minmax fractional programming problem are formulated, and then some appropriate duality theorems utilizing various new classes of second-order (F,β, φ, ¢,p, θ,m)-univex functions are established. The obtained results generalize most of the results on duality models in th literature.
