Condition: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | In the invex problems, it is required to consider a same function ¿ for the objective and constraint functions. Because of this restriction, various difficulties are encountered in applications related to optimality and duality properties.…To improve this situation, in this work, the invexity with respect to different functions (¿i) is proposed to study optimality conditions and duality for nonlinear and multiobjective programming problems with or without differentiability. Under this generalized invexity or its extensions assumptions, new Kuhn-Tucker (Fritz-John) type necessary and sufficient conditions and various duality results are obtained for (non)-differentiable nonlinear and multiobjective problems with inequality constraints. Furthermore, characterizations of solutions are established under suitable generalized invexity with respect to different (¿i). Several examples are given to illustrate the obtained optimality results which generalize and extend previously known results in this area. The contents of this study should be accessible, usable and useful to students, researchers and practitioners in the areas of OR, optimization, applied mathematics, engineering, etc.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Bilevel programming is a tool for modelling two level hierarchical decision making. This class of programs constitutes a branch of mathematical programming in which the constraints are, partially, determined by another optimisation probl…em. The deci sion maker at the upper level is termed as the leader, and at the lower level the follower. The control of variables is partitioned between the decision makers who attempt to optimise their individual objectives. The leader goes first in order to optimise his/her objective function. The follower observes the leader's decision and constructs his/her decision. Bilevel programs are non-convex problems and have been proved to be NP-hard problems even in the simplest case where the objective and constraint functions are all linear. In this document, we study an extension of these problems. Precisely, we are concerned with Multiobjective bilevel optimization problems.

Pour améliorer cette situation, dans ce livre, l'invexité par rapport à différentes fonctions (eta-i) est proposée pour étudier les conditions d'optimalité et la dualité pour des problèmes de programmation non linéaire et multi-objectifs. Sous l'hypothèse de cette invexité généralisée ou de ses extensions, de nouvelles conditions nécessaires et suffisantes de type Kuhn-Tucker (Fritz-John), des caractérisations des solutions et plusieurs résultats de dualité sont obtenus pour des problèmes non-linéaires et multi-objectifs (non)-différentiables avec contraintes d'inégalité. Plusieurs exemples sont donnés pour illustrer les résultats d'optimalité obtenus qui généralisent et étendent des résultats connus dans ce domaine. Le contenu de cette étude devrait être accessible, utilisable et utile aux étudiants, aux chercheurs et aux praticiens dans les domaines de la RO, l'optimisation, les mathématiques appliquées, l'ingénierie etc.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - La résolution des problèmes d'optimisation multi-niveaux est devenue un sujet d'actualité sur le plan théorique et application. Etant donnée la difficulté de résolution numérique de cette classe de problèmes, même pour le cas des program…mes bi-niveaux linéaires, on rencontre différentes approches dans la littérature.Dans le cadre de ce manuscrit, l'intérêt est porté à la résolution numérique d'un programme bi-niveaux linéaire avec des contraintes du Leader. L'approche utilisée consiste à remplacer le problème du Suiveur par ses conditions d'optimalité de Karush-Kuhn-Tucker. Le problème obtenu est résolu par une combinaison de la méthode de pénalité exacte, la méthode DC et l'algorithme DCA. Une étude comparative avec d'autres méthodes de résolution est donnée.
