Conception d'un système d'aide à l'ordonnancement tenant
compte des impératifs économiques

Abstract : Our works deal with the implementation of methodologies for production resolution and optimization taking into consideration economic imperatives, which are important parts in industrial manufacturing control. For the flexible job-shop problem, five criteria are considered: Makespan, the workload of the critical machine, the total workload of machines, the penalties of earliness/tardiness and the production cost. In this direction, the decision and evaluation problems are introduced and studied, and three integrated approaches, based on genetic algorithms, improving evolutionary approaches which exist in the literature, are presented: static method based on Choquet's integral, approached method based on the Pareto-optimality concept as well as the method based on the concept of ε-dominance Pareto-optimality.

The proposed approaches are used to generate a variety of optimal solutions needed to help the decision-maker, when he can not give a particular preference to one of the objective functions. Proposed results, obtained globally for the overall of criteria, are successfully compared with those obtained by other existing approaches on several benchmarks presenting different complexities.
