Full definition
Statistical distribution used in reliability engineering to model component life with three parameters: β (shape/failure pattern), η (scale/characteristic life) and γ (location). β<1: infant mortality; β=1: random failures (exponential); β>1: accelerated age-related wear. η represents life at 63.2% probability of failure. Developed by Wallodi Weibull (1951). Software: ReliaSoft Weibull++, Minitab, R. Enables estimation of optimal preventive replacement intervals and analysis of component warranties.
