What type of maintenance is scheduled after observing wear patterns during operation?

1. Predictive maintenance

2. Preventive maintenance

3. Corrective maintenance

4. Reactive maintenance

The correct answer is: Predictive maintenance

Predictive maintenance is designed to anticipate and address equipment issues based on data collected during operation. It involves monitoring wear patterns and performance trends, enabling maintenance to be scheduled at optimal times before failures occur. This proactive approach reduces downtime and maintenance costs, as it only intervenes when signs indicate a potential problem. By analyzing the wear patterns, technicians can predict when components may fail and schedule maintenance accordingly, ensuring that machinery remains operational and efficient. This is distinct from other types of maintenance that may not rely on such predictive measures.
