AFE Maintenance Planning & Reliability Engineering

Question 1

What is the primary goal of Reliability-Centered Maintenance (RCM)?

Accepted Answer

Preserve system function by selecting appropriate maintenance strategies

Answer

Eliminate all scheduled maintenance tasks

Answer

Reduce maintenance staff headcount

Answer

Maximize equipment replacement frequency

Question 2

Which maintenance strategy involves replacing components at fixed time intervals regardless of their condition?

Accepted Answer

Preventive (time-based) maintenance

Answer

Predictive maintenance

Answer

Condition-based maintenance

Answer

Run-to-failure maintenance

Question 3

Mean Time Between Failures (MTBF) is best described as:

Accepted Answer

The average operating time between successive failures of a repairable system

Answer

The average time to repair a failed asset

Answer

The probability that equipment will fail within a given period

Answer

The total number of failures divided by operating cost

Question 4

In a Failure Mode and Effects Analysis (FMEA), what is the Risk Priority Number (RPN) calculated from?

Accepted Answer

Severity × Occurrence × Detection

Answer

Probability × Impact × Cost

Answer

Frequency × Downtime × Labor cost

Answer

Severity × Probability × Repair time

Question 5

Which condition-monitoring technique uses sound waves to detect bearing defects and lubrication issues?

Accepted Answer

Ultrasonic testing

Answer

Thermography

Answer

Vibration analysis

Answer

Oil analysis

Question 6

Overall Equipment Effectiveness (OEE) is calculated by multiplying which three factors?

Accepted Answer

Availability × Performance × Quality

Answer

Uptime × Speed × Yield

Answer

Reliability × Maintainability × Availability

Answer

MTBF × MTTR × Utilization

Question 7

A P-F curve in predictive maintenance represents:

Accepted Answer

The interval between a potential failure and a functional failure

Answer

The relationship between planned vs. forced outages

Answer

The cost curve of preventive versus corrective maintenance

Answer

The probability of failure over the equipment's lifespan
