Flexibilité de production et rentabilité des investissements - L'exemple de la robotisation de l'assemblage tôlerie en soudage par points

    [fre] Les études de rentabilité marginales ne suffisent pas à formaliser l'intérêt économique des ateliers flexibles. La décision de leur développement doit s'analyser sur longue période. D'autre part, on ne peut plus raisonner en termes de comparaisons entre techniques différentes à produit identique. Enfin, les sommes en jeu amènent à faire un compromis entre le développement d'automatisations flexibles, économisant des investissements dans un futur plus ou moins lointain, et la croissance de la gamme de produits avec des techniques traditionnelles. Toutes ces raisons confèrent à ces décisions un caractère stratégique. Elles ne s'intègrent pas aisément dans le schéma classique du classement des projets d'investissements par ordre décroissant de rentabilité. Des outils d'analyse appropriés peuvent cependant éclairer ces décisions et leur optimisation sur le plan économique. [eng] The decision to develop flexible assembly shops must be supported by more than the traditionnal marginal studies, shiefly for three reasons : — the economic advantages of these shops appear on long period, — the decision between developping or not doesn't refer to the same products, — the high level of their cost implies less possibilities of growth of the production capacities. This decision is strategic. However, it is possible to create proper tools in order to instruct and justify it on the economical point of view.
