Product traceability integration within process for more precise diagnosis

To master the production it is necessary to be able to adapt the control of this one to the characteristics of a product and individually to ensure the traceability of this last. This way, the product can be considered as the pivot that ensures coherence between the levels of management and manufacture execution. Thus, it becomes necessary to control the production through the product, at the moment "t" and/or through time interval. We present in this article, the problems of production follow-up met within an existing system of production industrial; as well as the used methodology and tools which made it possible to rebuild, by means of systematic recordings, all the process history, to identify the useful elements with precision and to determine the element which acted, which was made or used, at which time, etc.
