Depuis son introduction, la programmation mathématique à deux niveaux suscite un intérêt toujours croissant. En effet, vu ses applications dans une multitude de problèmes concrets (problèmes de gestion, planification économique, chimie, sciences environnementales,...), beaucoup de recherches ont été effectuées afin de contribuer à la résolution de cette classe de problèmes. Cette thèse est consacrée à l'étude de quelques classes de problèmes d'optimisation à deux niveaux, à savoir, les problèmes à deux niveaux forts, les problèmes à deux niveaux forts-faibles et les problèmes à deux niveaux semi-vectoriels. Le premier chapitre est consacré aux rappels de quelques définitions et résultats de topologie et d'analyse convexe que nous avons util...
