When developing a maintenance schedule, 'schedule compliance' is measured as:
Answer: The percentage of planned work orders completed as scheduled
Schedule compliance measures what percentage of planned maintenance work orders are completed within the scheduled period, reflecting planning and execution effectiveness.
A plant experiences repeated seal failures on centrifugal pumps. The maintenance team suspects misalignment. Which alignment method provides the highest precision?
Answer: Laser shaft alignment
Laser shaft alignment provides the highest precision and repeatability for aligning rotating machinery, reducing vibration, seal wear, and bearing failures.
A plant manager wants to benchmark maintenance performance against industry peers. Which metric is most commonly used for this comparison?
Answer: Maintenance cost as a percentage of replacement asset value (RAV)
Maintenance cost as a percentage of RAV normalizes spending to asset value, making it the most widely used metric for cross-industry maintenance benchmarking.
In the context of spare parts management, 'ABC analysis' is used to:
Answer: Categorize spare parts by their usage value to optimize inventory investment
ABC analysis classifies spare parts into A (high-value, low-volume), B (moderate), and C (low-value, high-volume) categories to focus inventory control efforts appropriately.
Which maintenance concept focuses on designing equipment so that it can be easily and quickly restored to operating condition after a failure?
Answer: Maintainability
Maintainability is the measure of how easily and quickly a failed system can be restored to its functional state, often expressed as Mean Time To Repair (MTTR).
A plant is evaluating whether to rebuild an aging compressor or replace it. Which economic analysis tool is most appropriate for comparing these alternatives over a multi-year period?
Answer: Life Cycle Cost (LCC) analysis
Life Cycle Cost analysis compares total costs of ownership including acquisition, operation, maintenance, and disposal over the equipment's useful life to support replace-or-repair decisions.
During a plant shutdown, a maintenance crew performs work that was identified during routine inspections but deferred until the scheduled outage. This practice is known as:
Answer: Deferred corrective maintenance
Deferred corrective maintenance refers to identified repair work that is deliberately postponed and bundled into a planned shutdown to minimize production disruption.
