  1. What does MTBF stand for in reliability engineering?

    Answer: Mean Time Between Failures

    MTBF (Mean Time Between Failures) measures the average time between successive failures of a repairable system.

  2. How is Overall Equipment Effectiveness (OEE) calculated?

    Answer: Availability × Performance × Quality

    OEE is calculated by multiplying Availability, Performance, and Quality rates together.

  3. What does MTTR measure in a reliability context?

    Answer: Mean Time To Repair

    MTTR (Mean Time To Repair) is the average time required to restore a failed system to operational status.

  4. A plant has 720 operating hours with 3 failures. What is the MTBF?

    Answer: 240 hours

    MTBF = Total operating time ÷ Number of failures = 720 ÷ 3 = 240 hours.

  5. Which KPI best measures the probability that equipment will operate without failure for a given period?

    Answer: Reliability

    Reliability is specifically defined as the probability of a system performing its required function for a specified time under stated conditions.

  6. What is equipment availability if MTBF = 200 hours and MTTR = 8 hours?

    Answer: 96.2%

    Availability = MTBF ÷ (MTBF + MTTR) = 200 ÷ (200 + 8) = 200 ÷ 208 ≈ 96.2%.
