Mean time between failures may go up to 15 years.

One issue is the mean time between failures due to metal fatigue.

As a computer system grows in complexity, the mean time between failures usually decreases.

The reliability increased from 32 hours mean time between failures to a requirement of 65 hours.

Numerically, this lambda is also the reciprocal of the mean time between failures.

Maintenance and thermal design: Critical in order to maximize up-time (the time between failures or crashes).

The average time between failures of the aircraft or components is 25 hours, while the minimum required is 100 hours.

The ground control station's time between failures is 27 hours, while the minimum time required is 150 hours.

Graphs were drawn and projections made about performance, maintenance man-hours, mean time between failures and, of course, costs.

It helps if the time between failures is as long as possible, but this is not specifically required in a fault-tolerant system.

For repairable components like a replaceable light bulb the concept of mean time between failures is used to describe the failure rate.

MTBF can be calculated as the arithmetic mean (average) time between failures of a system.

Mean time between failures (MTBF) are quoted in hundreds of years.

Life span is usually measured in mean time between failures (MTBF).

The mean time between failures is better than 900 hours with Built-in test equipment (BITE).

In practice, the mean time between failures (MTBF, 1/λ) is often reported instead of the failure rate.

Many hard-drive manufacturers include a Mean Time Between Failures figure on product packaging or in promotional literature.

The Ariete's engine had to run at a high RPM to perform well, thus reducing the operating time between failures.

Among the most common measures of reliability are the mean time to first failure, the mean time between failures, and the failure rate per unit time.

Mean Time Between Failures (MTBF) is closely related to failure rate.

Mean time between failures: The first components it is expected to fail in a TMOS technology is the illumination system.

In actual, real-time situations involving Minuteman missiles, the mean time between failures (MTBF) was over 5.5 years.

Also, because of the vacuum tube electronics, the radar system (like most other early generation radars) had a low mean time between failures (MTBF).

It is typically expressed as either number of failures-in-time (FIT), or mean time between failures (MTBF).

The reliability of such systems can be calculated statistically and is stated as the mean time to failure, which is a variant of mean time between failures.
