Reusability Assessment of Components in Consumer Products – a Statistical and Condition Monitoring Data Analysis Strategy
نویسندگان
چکیده
This paper presents a two-stage integrated approach to assess the reliability of components for reuse in the second life cycle. Statistical data analysis, the first stage of the proposed method, determines the mean life of components by analysing the time-to-failure data for an electric motor and gearbox of a washing machine. A well-known reliability assessment method, Weibull analysis has been used in this phase. The second stage deals with analysing the condition monitoring data. This step estimates the actual (used) life of components under real operating environment by linear multiple regression. Both of these stages are then integrated to assess the remaining useful life of components at the end of life of a product. The suggested model shows that at the end of the first life cycle, the electric motor and gearbox of a washing machine possess a remarkable amount of residual life that offers immense potential for reuse of these components.
