Abstract

Pour appliquer les algorithmes d’optimisation multi-objectifs à des problèmes de mise enforme des métaux très coûteux en temps de calcul, nous étudions le couplage del’algorithme génétique NSGA-II proposé par Deb à un métamodèle inspiré de la méthode desdifférences finies sans maillage de Liszka et Orkisz. Nous soulignons l’importanced’améliorer itérativement le métamodèle au cours des itérations d’optimisation, et lapossibilité de déterminer avec précision des fronts optimaux de Pareto des problèmesmulti-objectifs étudiés en moins d’une centaine de calculs.
