Efficience d’un système bâti sur le TRS global par poursuite du diagramme de fiabilité

The efficiency of the system built in the global OEE per pursuit of the Reliability Block DiagramThe OEE (Overall Equipment Effectiveness) has become across the NFE 60-182 norm, one of the major performance indicator of the efficiency of the production systems. It integrates essentially three notions (Quality, Availability, and Performance) depended in internal of the reliability and the maintenance logistic. If the evaluation of one element’s OEE can be easy,  his expression for a complex system is too difficult (the taking into account of redundancies, of temporal scale’s factors, of desynchronization, …). The use of the functional synchronized approach can bring solutions comparable to the block diagram reliability. We present in this paper a method of evaluation of the efficiency and the procedures of calculation of the OEE based in the global structure of systems (series and parallels) and the objectives of production (nominal and degraded)
