Cette thèse, présente des contributions à la résolution (sur les GPUs) de problèmes d'optimisations réels de grandes tailles. Les problèmes de tournées de véhicules (VRP) et ceux de localisation des hubs (HLP) sont traités. Diverses approches et leur implémentions sur GPU pour résoudre des variantes du VRP sont présentées. Un algorithme génétique (GA) parallèle sur GPU est proposé pour résoudre différentes variantes du HLP. Le GA adapte son codage, sa solution initiale, ses opérateurs génétiques et son implémentation à chacune des variantes traitées. Enfin, nous avons utilisé le GA pour résoudre le HLP avec des incertitudes sur les données.Les tests numériques montrent que les approches proposées exploitent efficacement la puissance de calc...
