Abstract:
1. Method for controlling the operation of a system, sub-system or component, comprising the steps of a) repeatedly recording an operation time of said system, sub-system or component and at least one further parameter of said system, sub-system or component, wherein the further parameter is indicative of stress in the system, sub-system or component and results in an accumulated stress effective to cause aging and reduce an operational lifetime of the system, sub-system or component; b) evaluating a usage profile based on said recorded operation tune and said at least one further parameter, said usage profile being indicative of the accumulated stress at the time of the evaluation, and c) if a difference between said evaluated usage profile and a nominal usage value at the time of the evaluation exceeds a predetermined threshold value, adjusting at least one operation parameter of said system, sub-system or component to reduce said stress in said system, sub-system or component.
