A simulation model for opportunistic maintenance strategies

Abstract

An opportunistic maintenance strategy is proposed to maintain a production line consisting of k nonidentical processors and without intermediary stocks. Operational characteristics of processors are degraded with usage. In this strategy, preventive maintenance activities are combined with corrective ones as soon as a certain technical and economical conditions are satisfied. This might reduce the total number of maintenance activities and consequently the total maintenance cost incurred. Performance evaluation of a such a strategy is carried out using a simulation model.
