An Alternative to the Exponential and Weibull Reliability Models

The two reliability models most widely used in engineering applications are the exponential and Weibull. Both deficient because their failure rates do not conform to bathtub curve nor specify infant mortality period. In addition, Weibull require lifetime data which entails testing or field observations usually proprietary. advantage of model is that it can be supported by both MIL handbook data, latter being publicly available. this article, an alternative single parameter — called formulated whose rate conforms shape asymmetric curve. It shown that, unlike present multiparameter models, data. ramifications will demonstrated through three applied examples: engine fan, microcomputer, crystal oscillator. supportability claim substantiated constructing estimation procedure microcomputer oscillator examples. Calculations show predict twice as many fan failures article model. For example, gives one-half times faults.
