Method for controlling the operation of a system, sub-system or component
First Claim
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 relevant to system, sub-system or component aging b) 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, 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.

Abstract
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 of
a) 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 aging
b) 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, 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 an operation parameter of said system, sub-system or component.
