摘要

Missing degradation data is common in accelerated degradation testing and prognostic and health management, which may bring a lot of difficulties for degradation modeling and life prediction, and lead to inaccurate prediction results. In this paper, the regression analysis and RBF neural network algorithm are used to estimate the trend and fluctuation of missing data respectively, and the estimations are combined to handle with the missing degradation data. The proposed method could make the trend and fluctuation of imputation data better fit the observed data. An engineering case study on a microwave component’s degradation data is conducted to demonstrate the effectiveness of the proposed method.
