MAINTENANCE

Part 1

P reventive Maintenance (PM) is the best approach in modern technology to mitigate the high cost of downtime in most organizations with constrained capacity and resources. Preventive maintenance can reduce the likelihood of failures and downtime; however, it can incur unnecessary, expenses, and waste if done too frequently or without proper justification. Undertaking a block replacement policy under PM can lead to “over-maintenance” if inspection before replacement is not utilized. Parts recently replaced based on corrective maintenance still contain potency; if they are replaced and scrapped, that increases maintenance costs and waste. Hence, using predictive maintenance along with PM could significantly enhance maintenance optimization and asset performance. Predictive maintenance can improve the efficiency and effectiveness of maintenance activities by using inspection and data analytics to forecast failures and optimize maintenance schedules. Moreover, Internet of Things (IoT) devices allow for monitoring predictable failures in prior planning. However, exploiting these techniques may also require more investment in technology and expertise.
