Adapting An Age-Reduction Model to Extend The Useful-Life Duration
Most of the proposed age-reduction models was introduced and widely used in applications only for the case of monotonically increasing failure rates.However,from a practical perspective,there are several situations for which failure rates are decreasing or bathtub shaped.In these cases,the existing imperfect maintenance models may lead to the restoration of a system to the infant mortality period and can be considered as harmful.In this paper,we modify the usual assumptions on traditional age-reduction models to take into account the bathtub-shaped failure rates.Finally,we provide a numerical example to illustrate our result.
