Mean time between failures (MTBF) describes the expected time between two failures for a repairable system. For example, three identical systems starting to function properly at time 0 are working until all of them fail. … See more

MTBF serves as a crucial metric for managing machinery and equipment reliability. Its application is particularly significant in the … See more

There are many variations of MTBF, such as mean time between system aborts (MTBSA), mean time between critical failures (MTBCF) or … See more

The MTBF is the expected value of the random variable $${\displaystyle T}$$ indicating the time until failure. Thus, it can be written as See more

The MTBF value can be used as a system reliability parameter or to compare different systems or designs. This value should only be … See more

Two components $${\displaystyle c_{1},c_{2}}$$ (for instance hard drives, servers, etc.) may be arranged in a network, in See more

• Annualized failure rate – Probability that a device or component will fail during a year of use
• Failure rate – Frequency with which an engineered system or component fails
• Frames per stop – Term of reliability in the bowling industry See more
