Predicting Unknown Failures

For the prediction of failures of technical systems, a new method has been found which can be used in addition to the established methods FMEA and AFD. It is based on the idea of describing a system by means of a set of standard system parameters. The values of these are varied and the effects of the varied parameters are assessed. Since a failure as a faulty system state is one set of parameter values among others, it is expected to show up by their variation. This procedure does not require knowledge of the specific failure type.
