Abstract

The article presents a comparative study on the strategies of scheduling unites maintenance/production in the workshops of the type flow shop of permutation. Two strategies are presented: the sequential strategy which resolution is done in two stages: initially we schedule the tasks of production then integrate the tasks of maintenance, taking the scheduling of the production as a strong constraint. The integrated strategy is the representation of the tasks of maintenance and production. The objective is to optimize an objective function which takes into account the criteria of maintenance and production at the same time. The Genetic Algorithms (AGs) proved their effectiveness in the scheduling of the production. A comparison among different heuristics implemented will conclude this work.
