Optimality Conditions for Bilevel Multiobjective Set-Valued Optimization Problems

This paper investigated the bilevel optimization problems with multiobjective in both upper level and lower level problems in the framework of set value analysis. It established a unified model to deal with the problems, where the set valued function of the upper level problem is determined implicitly by the efficient frontiers of the lower level problem. And then explored the contingent derivatives, cone convexity, cone monotonicity and upper locally Lipschitz property of the set valued functions involved in the model, respectively. Based on these and by the theories and methods of parametric programming, nonsmooth analysis and nonlinear analysis, the necessary and sufficient optimality conditions of cone efficient solutions for the model were obtained.
