Statistics and Probability Knowledge
There are many standard statistical
distributions which may be used to model the various
engineering and reliability parameters. It has been found that
a relatively small number of statistical distributions
satisfies most needs in engineering and reliability work. The
particular distribution used depends upon the nature of the
data, in each case.
The following are some of the
distributions most commonly used in engineering and
reliability analysis, criteria for their use, and examples of
application. The tables below, Table A and B are summaries
of the shape of common failure density, reliability, and
hazard rate functions for the distributions described.
