Abstract

The requirement for reliable methodologies to assess the remaining useful life of used components has become crucial in order to implement various end-of-life strategies. This article presents the latest development in predicting the remaining useful lifetime of used components. It takes the physical and the technological life aspects into account for an integrated assessment. There are three main parts of this article. First, the remaining physical life of used components is derived based on the failure rate data and the statistical analysis of usage life. Secondly, the use of technology forecasting technique to predict the remaining technological life. Finally, the resulting estimations from the two aspects are combined to obtain an integrated assessment for estimating the remaining useful life of components.
