Predictive maintenance

Definition

Predictive maintenance is a proactive approach to equipment maintenance that utilizes data analysis and monitoring to predict when maintenance should be performed, rather than following a fixed schedule. This technique helps identify potential failures before they occur, reducing downtime and improving overall system reliability. By leveraging real-time data and advanced analytics, predictive maintenance enhances operational efficiency and can be integrated with various technologies to strengthen control strategies and resilience.
