Optimality and duality in non-differentiable interval valued multiobjective programming
Izhar Ahmad, Deepak Singh, Bilal Ahmad Dar · International Journal of Mathematics in Operational Research · 2017
In this paper, Fritz-John and Kuhn-Tucker type necessary and sufficient conditions for a non-differentiable interval valued multiobjective optimisation model are established. LU-convexity of interval valued functions is utilised to obtain interval efficient solution for the given problem. Moreover, weak, strong and strict converse duality theorems for Wolfe and Mond-Weir type duals are obtained in order to relate the interval efficient solution of primal and dual problems.
