A new method coupling simulation and a hybrid metaheuristic to solve a multiobjective hybrid flowshop scheduling problem
Résumé
In this paper, we have studied a multiobjective hybrid flowshop scheduling problem where n independent jobs should be executed in a hybrid assembly line. The aim of our work is to optimize the makespan and the total tardiness of the whole production. A simulation based optimization algorithm is proposed here to solve this problem. It is a combination of the simulation software ARENA and the FLC-NSGA-II optimization method. The latter uses a fuzzy logic controller to adjust the crossover and the mutation probabilities, in order to enhance the research ability of the traditional NSGA-II algorithm. This method is first compared with the industrial solutions, and then with NSGA-II. The result shows the efficiency and the feasibility of our proposed method.
