AMP AMP Asset Maintenance & Reliability 2 — Questions and Answers
Question 1: What is the primary goal of a preventive maintenance program?
- Eliminate all unplanned downtime overnight
- Reduce failure probability through scheduled interventions (Correct answer)
- Replace assets before they reach five years old
- Minimize labor hours spent on maintenance
Correct answer: Reduce failure probability through scheduled interventions
Preventive maintenance aims to reduce the probability of failure by performing scheduled tasks such as lubrication, inspection, and part replacement at fixed intervals.
Question 2: Which analysis technique identifies the root causes of equipment failures using a diagram shaped like a fish skeleton?
- Pareto analysis
- FMEA
- Ishikawa (fishbone) diagram (Correct answer)
- Fault tree analysis
Correct answer: Ishikawa (fishbone) diagram
The Ishikawa (fishbone or cause-and-effect) diagram visually maps potential root causes of a failure across categories like people, process, equipment, and environment.
Question 3: MTTR in reliability management stands for:
- Mean Time To Repair (Correct answer)
- Maximum Throughput To Revenue
- Minimum Total Time Required
- Mean Task Turnover Rate
Correct answer: Mean Time To Repair
MTTR (Mean Time To Repair) measures the average time required to restore a failed asset to full operational status.
Question 4: Which type of maintenance task is best suited for assets whose failure mode follows a random failure pattern?
- Time-based replacement
- Condition-based monitoring (Correct answer)
- Corrective maintenance only
- Scheduled overhaul every 12 months
Correct answer: Condition-based monitoring
For assets with random failure patterns, condition-based monitoring is most effective because time-based intervals cannot predict when a random failure will occur.
Question 5: A maintenance backlog in asset management refers to:
- Completed work orders awaiting sign-off
- Approved maintenance work not yet completed (Correct answer)
- Spare parts ordered but not yet received
- Deferred capital replacement projects
Correct answer: Approved maintenance work not yet completed
A maintenance backlog is the accumulation of approved and prioritized work orders that have been identified but not yet executed.
Question 6: Which standard is most commonly referenced for physical asset management systems, including maintenance?
- ISO 9001
- ISO 55001 (Correct answer)
- ISO 14001
- ISO 31000
Correct answer: ISO 55001
ISO 55001 is the international standard for asset management systems and provides requirements applicable across the full asset lifecycle, including maintenance.
