Moreover, the reproduction of such Quality Management System (QMS) requires both modeling and piloting. For modeling, a Multi-Agent System (MAS) approach using a micro framework between the agents based on the sequence diagram UML (Unified Modeling Language) was proposed. For piloting, the proposed method is the Hierarchical Fuzzy Signatures (HFS) that is one of the best methods adopted for this kind of problems. To validate this developed system, an industrial company which presents a major problem for controlling the quality level of production lines was chosen. The achieved results have shown that HFS concept is effective, efficient and flexible for piloting such model QMS-MAS. April - June 2010 Copyright © 2010 i-manager publications.
