- Abstract
Online and offline adaptive maintenance policies are presented for the systems with non-stationary Wiener degradation processes. In the policies, preventive maintenance threshold will change with the degradation indicator adaptively. The cumulative sum algorithm is used in the online model to detect the change point of the degradation process. On this basis, an analytical model of the offline model is developed. A gearbox case based on the vibration-based degradation signals is studied to show the performance of the maintenance policy. It shows that it is important to consider the change point and to be of high effectiveness using the adaptive maintenance model.
