Table 1 Comparative analysis of CM and PM.
From: Strategical selection of maintenance type under different conditions
Aspect | Corrective maintenance | Preventive maintenance |
|---|---|---|
Definition and focus | Reactive repairs after failure | Proactive measures to prevent failures |
Timing and response | After failure occurs | Regularly scheduled maintenance activities |
Cost implications | Potentially higher overall costs | Long-term cost savings through prevention |
Operational disruptions | Potential production delays | Minimized operational disruptions |
Approach | Reactive | Proactive |
Objective | restore functionality | Increase reliability and lifespan |
Downtime | Unplanned downtime | Planned maintenance downtime |
Resource allocation | Usage of resources after failure | Regular allocation for maintenance tasks |
Potential issues | Production losses, emergency repairs | Major failures, unexpected breakdowns |
Long-term effects | Short-term cost effectiveness | Improved reliability and cost savings |
