Proper efficiency and duality for a new class of nonconvex multitime multiobjective variational problems [PDF]
, 2014 In this paper, a new class of generalized of nonconvex multitime multiobjective variational problems is considered. We prove the sufficient optimality conditions for efficiency and proper efficiency in the considered multitime multiobjective variational ...

International Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 9, Page 621-628, 2001., 2001 A new method for obtaining sensitivity information for parametric vector optimization problems (VOP) v is presented, where the parameters in the objective functions and anywhere in the constraints. This method depends on using differential equations technique for solving multiobjective nonlinear programing problems which is very effective in finding ...

Symmetric duality for a class of multiobjective programming
International Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 9, Page 617-625, 2000., 2000 We formulate a pair of symmetric dual nondifferentiable multiobjective programming and establish appropriate duality theorems. We also show that differentiable and nondifferentiable analogues of several pairs of symmetric dual problems can be obtained as special cases of our general symmetric programs.

Characterizations of the Solution Sets of Generalized Convex Fuzzy Optimization Problem
Open Mathematics, 2019 This paper provides some new characterizations of the solution sets for non-differentiable generalized convex fuzzy optimization problem. Firstly, we introduce some new generalized convex fuzzy functions and discuss the relationships among them. Secondly,

On stability of a Pareto-optimal solution under perturbations of the parameters for a multicriteria combinatorial partition problem [PDF]
Computer Science Journal of Moldova, 2008 We consider a multicriteria variant for the well-known partition problem. A formula of the stability radius for an efficient solution was obtained. Mathematics Subject Classification 2000: 90C27, 90C29, 90C31.

On stability of Nash equilibrium situations and Pareto optimal situations in finite games [PDF]
Computer Science Journal of Moldova, 2003 A non-cooperative finite game of several persons is considered in the case, where payoff functions are linear. Extreme levels of independent perturbations of payoff functions parameters, which remain Nash and Pareto optimality of a situation, are ...

The Analytic Hierarchy Process, Max Algebra and Multi-objective Optimisation [PDF]
, 2012 The Analytic Hierarchy Process (AHP) is widely used for decision making involving multiple criteria. Elsner and van den Driessche introduced a max-algebraic approach to the single criterion AHP.

Postoptimal analysis of one lexicographic combinatorial problem with non-linear criteria [PDF]
Computer Science Journal of Moldova, 2009 In this article we consider a multicriteria combinatorial problem with ordered MINMIN criteria. We obtain necessary and sufficient conditions of that type of stability to the initial data perturbations for which all lexicographic optima of the original ...

Optimality and duality in set-valued optimization utilizing limit sets
Open Mathematics, 2018 This paper deals with optimality conditions and duality theory for vector optimization involving non-convex set-valued maps. Firstly, under the assumption of nearly cone-subconvexlike property for set-valued maps, the necessary and sufficient optimality ...
