Abstract

A new class of generalized functions ( 𝑑 - 𝜌 - 𝜂 - 𝜃 ) -type I univex is introduced for a nonsmooth multiobjective programming problem. Based upon these generalized functions, sufficient optimality conditions are established. Weak, strong, converse, and strict converse duality theorems are also derived for Mond-Weir-type multiobjective dual program.
