Abstract:

This paper presents two approaches for selecting qualified-for-reuse components for returned systems. Physical properties and age are used to assess the components’ residual lifetimes. Only components in the acceptable state are qualified for reuse. For a large number of components to be sorted only the ones whose ages are below a certain threshold are evaluated. This age threshold is estimated so that the proportion of components in the unacceptable states does not exceed the standard significance level. The proposed approach has been applied to the end of life of electric-powered wheelchair batteries.
