Accelerated testing (AT) is widely used to demonstrate and assess product reliability and is especially useful for products with long life and high reliability requirements. Currently, research is primarily focused on test planning, acceleration model and parameter estimation for AT of specific products, such as electronic and mechanical components, etc. In our application, for several components...
The performances of some systems contain multiple parameters, and each parameter has a degradation process caused by gradual degradation and random shocks. This paper proposed a procedure to estimate the reliability of these systems. Firstly, the degradation processes are obtained through performance degradation analysis according to the degradation data when random shocks are not considered. Then...
Accelerated degradation test (ADT) is widely used to evaluate the reliability of highly reliable products with long life if there exists a product quality characteristic whose degradation over time can be related to reliability. It is still a main challenge that how to design optimal plan, including sample size, measurement frequency, and termination time, for ADT which can result in the most accurate...
