The trick to PM optimization (reduction) and proper deployment of predictive maintenance tools is first to know how to categorize the assets, using analysis methods designed to understand likely and costly failure modes. Then with that knowledge, review the existing preventive maintenance procedures. Eliminate those that are either not addressing failure modes or are applied to asset types that don’t observe any time-based pattern. Once these steps are undertaken, the appropriate Predictive Maintenance strategies must be deployed. The result of this optimization of the maintenance program invariably results in a significant reduction in work, with the attendant reduction in labor and spare parts usage. In turn, these results drive significant cost savings and enhanced asset performance.
