AFE Maintenance Planning & Reliability Engineering 3

Question 1

A facilities engineer is reviewing the maintenance cost ratio (MCR). MCR is typically expressed as:

Accepted Answer

Annual maintenance cost as a percentage of estimated replacement asset value (ERAV)

Answer

MCR = (Annual Maintenance Cost / Estimated Replacement Asset Value) × 100%, providing a benchmark to compare maintenance spending to industry norms.

Question 2

Which scheduling technique prioritizes work orders by assigning numerical scores based on safety impact, production criticality, and waiting time?

Accepted Answer

Work order criticality ranking

Answer

Work order criticality ranking uses a scoring algorithm that weights factors like safety risk, equipment criticality, and backlog age to sequence maintenance work optimally.

Question 3

In predictive maintenance, infrared thermography is primarily used to identify:

Accepted Answer

Abnormal heat patterns indicating electrical or mechanical faults

Answer

Infrared thermography detects temperature anomalies in electrical panels, motors, steam traps, and insulation that indicate developing failures before they cause breakdowns.

Question 4

A key performance indicator (KPI) showing the percentage of total maintenance hours spent on planned versus unplanned work is called:

Accepted Answer

Planned maintenance percentage (PMP)

Answer

Planned Maintenance Percentage (PMP) = (Planned maintenance hours / Total maintenance hours) × 100%, indicating how proactive versus reactive a maintenance program is.

Question 5

Which approach to spare parts management minimizes carrying costs while ensuring critical parts are available when needed?

Accepted Answer

Applying criticality-based classification (e.g., ABC analysis) with reorder point triggers

Answer

ABC analysis classifies parts by criticality and usage frequency, setting appropriate stocking levels and reorder points to balance availability against carrying costs.
