Abstract:

In this paper, both Fritz John and Karush-Kuhn-Tucker necessary optimality conditions are established for a (weakly) LU-efficient solution in the considered nonsmooth multiobjective programming problem with the multiple interval-objective function. Further, the sufficient optimality conditions for a (weakly) LU-efficient solution and several duality results in Mond-Weir sense are proved under assumptions that the functions constituting the considered nondifferentiable multiobjective programming problem with the multiple intervalobjective function are convex.

Key words: nonsmooth multiobjective programming problem with the multiple intervalobjective function, Fritz John necessary optimality conditions, Karush-KuhnTucker necessary optimality conditions, (weakly) LU-efficient solution, MondWeir duality
