Accelerated degradation testing for systems with multiple performance parameters

Abstract

Accelerated degradation testing (ADT) provides an effective way to assess the reliability of products. In engineering application, reliability of some complex products is often characterized by multiple performance parameters. However, current methods for ADT are mostly focused on the case which involves single performance parameter. This paper proposes an analysis method for ADT based on multiple performance parameters, by considering the correlation among performance parameters. From the results of application examples, the analysis procedure of the proposed method is more reasonable and the estimates are more exact.
