In order to improve the reliability of a system, sub-system or component, a method for controlling the operation of a system, sub-system or component, comprises the steps ofa) repeatedly recording an operation time of said system, sub-system or component and at least one further parameter relevant to system, sub-system or component agingb) evaluating a usage profile based on said recorded operation time and said at least one further parameter, said usage profile being indicative of the accumulated stress at the time of the evaluation, andc) 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 an operation parameter of said system, sub-system or component.

1. Method for controlling the operation of a system, sub-system or component, comprising the steps ofa) 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. 2. Method according to claim 1, wherein said step c) is executed after a predetermined operation time of said system, sub-system or component.3. Method according to claim 1, wherein said step c) is executed if said evaluated usage profile indicates that the accumulated stress exceeds a predetermined threshold value.4. Method according to claim 1, wherein said step of adjusting an operation parameter comprises the step of calculating updated actuation parameters for said systems, sub-systems or components based on the operation history contained in said usage profile.5. Method according to claim 1, wherein said step of adjusting an operation parameter comprises the step of reducing the performance of said system, sub-system or component.6. Method according to claim 1, wherein said step of adjusting an operation parameter comprises the step of reducing the operation frequency or working time of said system, sub-system or component.
