WEIBULL’S DISTRIBUTION FUNCTION – TERMS FOR MEAN TIME TO FAILURE: STRUCTURES, COMPARISON, DIFFERENCES AND APPLICABILITY

Abstract

Two terms for determination mean time to failure, exist, first via gamma function, and second from distribution function for reliability or unreliability R(t) =F(t) = 0,5, are analysed in this paper. Comparison both of terms pointed that the time to failure is direct proportional with position parameter  and the gamma function  corespond K value, both in function of shape parameter  also on differences between gamma  and K values and their application, to.
