Definitions,ons must be precise. Now, we must accept that the description of reliability given in the introduction is inadequate for technical purposes. However, more formal definitions do not always agree. Thus we find the following definitions of reliability from highly respectable bodies European Organisatio

Probability as a measure of reliability,ecified period of time. Reliability can then be expressed by some number lying between zero and unity, where zero represents certain failure and unity certain success in the accepted manner. In this concept an item either succeeds or fails — there is no halfway house. (This matter is further discuss

Some statistical distributions,before examining field evidence. Perhaps the one used most extensively is the negative exponential distribution. We have already seen in section 4.4 how it can represent the variation of reliability with time for infinitely rough loading. In addition any period of constant failure rate can be repres

Design for reliability,e keystone to reliability. Presenting the 1974 James Clayton lecture to the Institution of Mechanical Engineers, which was intended to summarise eight conferences or symposia held by that body from the mid-sixties to the mid-seventies, the author concluded “the significant theme which has recurred o
