For example, if we are looking at 1000 drives for 1 year and find that 50 of the drives failed during the year, R = (1000-50)/1000 = 0.95. MTBF can be calculated to be 19.5 years using the formula above. The reas on why the un it of measure becomes years in this case is ...
In fact, Mean Time Between Failures is one-half of the formula used to calculate availability, along with MTTR (Mean Time to Repair). An equipment’s total uptime can be expressed as MTBF together with MTTR. Together, these two metrics are used to anticipate how likely an asset is to bre...

FORMULA: MTBF = (Total uptime) / (number of failures) or MTBF = 1 / Failure Rate What exactly is a "failure"? A complete stoppage is one obvious answer. Some may also consider a "failure" once the item or equipment experiences a slowdown or reduced performance from an ideal level, but...
The second part of the formula, the RETURN portion is really three pieces. If the current row is a maintenance task (PM), then we return 0 for uptime as we do not want those tasks included in our MTBF calculation. If our calculation for next is BLANK, then we know...
For example, if we are looking at 1000 drives for 1 year and find that 50 of the drives failed during the year, R = (1000 – 50)/1000 = 0.95. MTBF can be calculated to be 19.5 years using the formula above. The reason why the unit of measure becomes years in this case is that...

The formula for MTBF is as follows: MTBF = Total Operating Time / Number of Failures For example, if a piece of equipment operates for 10,000 hours and experiences 5 failures during that time, the MTBF would be 2,000 hours per failure. Reliability Engineering: MTBF is a fundamental ...
The MTBF formula is often used in the context of industrial or electronic system maintainability, where failure of a component can lead to significant downtime or even safety risks, but MTBF is used across many types of repairable systems and diverse industries. ...
2. Input your data into the following formula: MTBF = Total Uptime of Repairable Asset / Number of Failures of Asset within given time period. Divide your asset’s total number of operational hours by the number of failures it experienced within a given period to arrive at an hourly measurem...
