산업설비의 내용년수 추정을 위한 Weibull 생존곡선의 적용

A Study on the Application of Weibull Survivor Curves to Estimate Mortality Characteristics of Industrial Property

A mixture of two distributions, each belonging to the same known Weibull distributions, is proposed and a simple graphical method for estimating the parameters of the Weibull distribution is applied. It appears from the results of this study that the mixed Weibull distribution is an appropriate expression for describing industrial property mortality characteristics.
