One of the main objectives of Asset Performance Management is to maximize the net return on production assets. This requires maximizing availability by maintaining the assets in good health. This in turn is achieved by adopting a sound policy of maintenance interventions. Too much intervention is costly. Too little – again costly! In other words, we need to arrive at an optimal balance of proactive and reactive interventions.
Proactive maintenance includes any activity performed for maintaining an asset before it fails. Reactive maintenance is any maintenance activity performed after a failure. Proactive maintenance comprises the following activities: Emergency Preventive Maintenance (EPM), Preventive Maintenance (PM)and, Predictive Maintenance (PdM).
Reactive maintenance comprises two types: Emergency Corrective Maintenance (ECM) and Non-Emergency Corrective Maintenance (NCM). Achieving optimal balance would mean increasing the cost of Proactive Maintenance appropriately in order to reduce the cost of Reactive Maintenance substantially.
