On-line change detection and condition-based maintenance for systems with unknown deterioration parameters

摘要

The aim of this paper was to propose a condition-based maintenance policy for a gradually deteriorating system subject to change in the deterioration rate using on-line detection algorithms. The parameters of the deterioration rate after the change is unknown. The main purpose is to estimate these unknown parameters in order to adapt the condition-based maintenance policy and above all to optimize a global cost criterion.
