Nous nous intéressons dans cette thèse à la problématique de la décision collective. L’objectif est de déterminer une solution de compromis pour des problèmes soumis à de multiples points de vue. Les problèmes considérés sont de nature combinatoire. Plus précisément, il s’agit de la classe des systèmes d’ensembles qui ont une structure de matroïde. La théorie des matroïdes est centrale en optimisation combinatoire, elle a permis d’unifier des structures apparemment séparées comme les arbres et les couplages dans les graphes et elle a engendré des algorithmes efficaces pour résoudre des problèmes d’optimisation non triviaux en temps polynomial. Nous nous intéressons à fournir des algorithmes d’approximation polynomiaux centralisés et décentr...
