AMP AMP Asset Maintenance & Reliability 1 — Questions and Answers
Question 1: Which maintenance strategy involves performing repairs only after equipment has failed?
- Preventive maintenance
- Predictive maintenance
- Reactive maintenance (Correct answer)
- Condition-based maintenance
Correct answer: Reactive maintenance
Reactive maintenance (also called run-to-failure) is performed only after an asset breaks down or fails.
Question 2: What does OEE stand for in asset reliability management?
- Overall Equipment Effectiveness (Correct answer)
- Operational Efficiency Evaluation
- Output Engineering Estimate
- Overhead Expense Efficiency
Correct answer: Overall Equipment Effectiveness
OEE (Overall Equipment Effectiveness) measures availability, performance, and quality to assess how effectively manufacturing equipment is utilized.
Question 3: Predictive maintenance relies primarily on which type of data?
- Historical failure logs only
- Real-time condition monitoring data (Correct answer)
- Manufacturer warranty records
- Annual inspection reports
Correct answer: Real-time condition monitoring data
Predictive maintenance uses real-time condition monitoring data (vibration, temperature, oil analysis) to predict failures before they occur.
Question 4: Which reliability metric represents the average time between successive failures of a repairable asset?
- MTTF
- MTBF (Correct answer)
- MTTR
- RCM
Correct answer: MTBF
MTBF (Mean Time Between Failures) measures the average operating time between failures for a repairable asset.
Question 5: Reliability-Centered Maintenance (RCM) focuses primarily on:
- Reducing maintenance staff costs
- Ensuring safety and function at minimum cost (Correct answer)
- Maximizing equipment replacement schedules
- Increasing spare parts inventory
Correct answer: Ensuring safety and function at minimum cost
RCM is a systematic process to determine what must be done to ensure that assets continue to fulfill their intended functions safely and cost-effectively.
Question 6: A P-F curve in asset management describes the interval between:
- Purchase and first failure
- Potential failure and functional failure (Correct answer)
- Planned maintenance and actual downtime
- Production start and peak output
Correct answer: Potential failure and functional failure
The P-F curve illustrates the time between a detectable potential failure (P) and the actual functional failure (F), which defines the window for intervention.
