Cost saving and product improvement have always been important goals in the metal forming industry. To achieve them, metal forming processes need to be optimized, which consequently requires solving optimization problems. Usually these problems have multiple objectives; they aim at minimizing several objective functions in the presence of several explicit and implicit constraints. Each function evaluation is quite time consuming. To solve this type of problems, a robust and efficient algorithm is developed. It consists in coupling an evolutionary algorithm (a multi-objective genetic algorithm) with a metamodel (an approximation of the problem functions). Then, the number of expensive function evaluations can be significantly reduced by part...
