Remaining lifetime assessment of a deteriorating system operating under permanent effect of fluctuant environment
Résumé
This paper presents a degradation model considering a permanent impact of the environment on the system. A two-stage environment is considered; shocks impacting the degradation rates can occur in the stressed mode. We develop methods to estimate/detect the occurrence of shocks and to assess the remaining useful lifetime. The studied examples showed a good performance of the estimation/detection methods.
