Regarding Prognostics and Health Management (PHM), the stakes lie in system-level prognostics or even the prognostics of systems of systems, as decisions are usually made at system or platform level. In this paper, a method, which takes into account both the system redundancy and the adaptation of operational modes in degraded functioning, is proposed and formalized. This method makes the system-level prognostics more relevant. The main feature of the method is to re-compute the components Remaining Useful Life (RUL) using the degradation rate associated to the future operating mode(s) due to system reconfiguration. This results in an improvement of both the System (SRUL) and the components . The proposed method is applied on a simplified aircraft bleed valve system to illustrate its effectiveness. This method is primarily destined to aeronautic systems, which are usually resilient. It has not been tested whether or not it could be useful in other fields.
