OPTIMAL RECONFIGURATION POLICY TO REACT TO PRODUCT CHANGES
Résumé
The increasing frequency of product and process modifications may significantly mine the profitability of those production systems which are designed in a traditional way by considering only the current product requirements and, eventually, the expectations on future variations of the market volumes. Indeed, the product typically evolves during its life cycle, by changing its technological characteristics and therefore its requirements on the production system. As a consequence, the production system may be forced to run inefficiently and costly because it is no longer consistent with the modified product. This paper describes the reconfiguration problem of production systems and proposes the optimal reconfiguration policy to react to product changes on uniformly distributed market demand and uniformly distributed technological requirements. A numerical case based on a real problem supports the applicability of the proposed reconfiguration policy.
