Integration of Maintenance Strategies into Prognosis Process to Decision-Making Aid on System Operation

The importance of maintenance function has increased due to its role in keeping and improving the system availability and safety but also the product quality. To support this new role, the maintenance concept has undergone through several major developments to lead to proactive considerations mainly based on prognosis process allowing normally to select the best maintenance action to carry out. In this paper the extension of a prognosis process by means of the integration of maintenance alternative impacts is proposed. The deployment of this extended prognosis process follows a methodology based both on probabilistic and event approaches. The feasibility and added value of this new prognosis is experimented on the manufacturing TELMA platform supporting the unwinding of metal bobbins.
