Opportunistic maintenance of multi-equipment system: A case study

A case study on preventive maintenance (PM) of a multi-equipment system is presented in this paper. Each equipment of the system consists of many comp onents/subsystems connected in series. Because of the series structure, opp ortunistic maintenance (OM) policies are more effective for the components of the equipment. A new OM policy based on the classification of opportunit ies has been proposed. Various OM policies have been evaluated using simula tion modeling, and the new policy has been found to be more effective than the existing OM policies. The impact of this policy on the overall system h as also been simulated. Copyright (C) 2000 John Wiley & Sons, Ltd.
