Claim One:
1. A prognostic and health management method for monitoring an aging system, including a component of said system, said method useful for determining whether or not detected anomalies are due to natural aging or other aging processes, said method based on a combination of a conventional data-driven method and a moving window data-driven method, including the steps of: detecting anomalies of said system, or component of said system based on monitored parameters of the system using both the conventional data-driven method and the moving window data-driven method; and identifying whether said detected anomalies arc due to natural aging or other aging processes or causes wherein; if both methods do not detect any anomalies, the system or component is healthy; if the conventional data-driven method detects anomalies but the moving window method does not, the detected anomalies are due to natural aging; if both methods detect anomalies, the detected anomalies are caused by other aging processes besides natural aging; wherein said detecting and identifying steps are performed with the aid of a computer.
