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

Annual maintenance cost divided by annual revenue

Answer

Total labor cost divided by total parts cost

Answer

Corrective maintenance hours divided by total available hours

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

Critical path method (CPM)

Answer

First-in, first-out (FIFO) scheduling

Answer

Gantt chart leveling

Question 3

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

Accepted Answer

Abnormal heat patterns indicating electrical or mechanical faults

Answer

Corrosion rates in metal piping

Answer

Vibration frequencies in rotating equipment

Answer

Fluid contamination levels in hydraulic systems

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

Schedule compliance rate

Answer

Wrench time ratio

Answer

Emergency work order rate

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

Stocking maximum quantities of all parts at all times

Answer

Purchasing all parts on an emergency basis to avoid inventory costs

Answer

Standardizing on a single vendor for all spare parts purchases

Question 6

Total Productive Maintenance (TPM) is distinguished from traditional maintenance programs primarily by:

Accepted Answer

Involving equipment operators in routine care and minor maintenance tasks

Answer

Relying exclusively on outside contractors for all repairs

Answer

Eliminating all preventive maintenance in favor of run-to-failure

Answer

Focusing maintenance efforts solely on production equipment

Question 7

When performing a root cause analysis (RCA) after an equipment failure, the '5 Whys' technique is used to:

Accepted Answer

Iteratively ask 'why' to trace a failure back to its underlying root cause

Answer

Determine the replacement cost of the failed component

Answer

Rank potential causes by probability of occurrence

Answer

Establish the timeline of events leading up to the failure
