Optimisation multi-objectifs à base de métamodèle pour des applications en mise en forme des métaux

  • Mohsen Ejday and Lionel Fourment

Abstract

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