In this paper, we present the two inspection cycles (Good and Bad) of an optimal control-based framework of deteriorating systems that are subjected to repair and inspection. Two models were compared to ascertain which of the two that predict the mortality rate of transformers. The comparison revealed that the Makeham Model predicts the risk of failure by cause.
Keywords: Maintenability,Reability,Inspection,Gomrertz-Makehamanalysis, Meantime to failure, Meantime between failure.
