Maintenance Calculations

What does Meant Time Between Failure (MTBF) refer to?

• The time taken to repair equipment

• The average operation time before an unrepairable breakdown occurs

• The cost of repairing equipment

• The average operation time between unrepairable breakdowns

Meant Time to Repair (MTTR) is ______.

• the average time to manufacture equipment

• how quickly equipment can be returned to action after a breakdown

• the cost of repairing equipment

• the time taken to design equipment

What does MTBF stand for?

• Mean Time Before Failure

• Mean Time Between Failures

• Maximum Time Between Failures

• Minimum Time Before Failure

Fill in the blank: MTBF is calculated as the total operational time divided by the ________.

• repair duration

• number of breakdowns

• number of machines

• number of maintenance employees

What does MTTR stand for?

• Mean Time to Repair

• Maximum Time to Repair

• Minimum Time to Repair

• Mean Time to Respond

Fill in the blank: The MTTR indicates how fast an operator can repair a machine. If one maintenance team has a lower MTTR than the other, they are considered ______.

• Better

• Worse

• to have obtained Darpan status

• Equal

Which of the following is a key benefit of having a low MTTR?

• Increased downtime

• Higher repair costs

• Improved equipment availability

• More frequent breakdowns

Fill in the blank: A high MTBF indicates that a system is ______.

• quick to repair

• expensive to maintain

• reliable and has fewer failures

• prone to frequent failures

What is the primary purpose of calculating MTBF?

• To determine the cost of repairs

• To calculate the total operational time

• To assess the reliability of equipment

• To measure the speed of repairs

Which of the following best describes the relationship between MTBF and system reliability?

• MTBF has no impact on reliability

• Higher MTBF indicates lower reliability

• MTBF is inversely proportional to reliability

• Higher MTBF indicates higher reliability
