A comprehensive review of accelerated degradation testing

Accelerated life testing (ALT) and accelerated degradation testing (ADT) are two main kind of reliability accelerated testing technology. ALT is abroad studied by both statisticians and reliability engineers, but there are just a few researchers who study the theory and engineering practice of ADT. The comparison between ADT and ALT technologies, related background, degradation models, data analysis methods and design and optimization of ADT are described. The recent statuses of ADT technology and engineering application are summarized. The key techniques of ADT are also explored and some suggestions are given for further researches.
