Performance Reliability Prediction of Complex System Based on the Condition Monitoring Information

Abstract EN

Complex system performance reliability prediction is one of the means to understand complex systems reliability level, make maintenance decision, and guarantee the safety of operation.

By the use of complex system condition monitoring information and condition monitoring information based on support vector machine, the paper aims to provide an evaluation of the degradation of complex system performance.

With degradation assessment results as input variables, the prediction model of reliability is established in Winer random process.

Taking the aircraft engine as an example, the effectiveness of the proposed method is verified in the paper.
