Which maintenance concept is described as schedule-based and aims to prevent failures?

• A. Preventive Maintenance
• B. Run-to-Failure
• C. Predictive Maintenance
• D. Reactive Maintenance

Answer: (A)

Preventive maintenance is maintenance done on a schedule to prevent failures. It involves planned inspections, servicing, cleaning, lubrication, adjustments, and part replacements at regular intervals based on time or usage, all with the goal of catching wear and degradation before a failure occurs. This proactive, schedule-driven approach helps keep equipment reliable and reduces unexpected downtime. In contrast, run-to-failure means letting the asset operate until it fails and then repairing it, which is not schedule-based. Reactive maintenance is repairs made after a failure has occurred, also not scheduled. Predictive maintenance uses real-time condition monitoring to forecast when a failure will happen and schedules work accordingly, which is not strictly tied to a fixed schedule.
