Accelerated degradation test can be used to demonstrate the reliability target of highly reliable products with fully utilizing the degradation data within feasible test duration. There are a few works dealing with reliability demonstration based on degradation data. Most existing methods are applications with respect to linear degradation models and Wiener process models, which cannot describe the monotonic degradation process, such as fatigue cracks development of alloy products, wear of bearings, erosion of pipes, while Gamma processes are suitable. A method for accelerated degradation demonstration test based on Gamma process models is proposed in this paper. Firstly, reliability target is translated into the requirement of performance degradation. Then, a demonstration test plan based on Gamma process models is designed according to the requirements of the consumer risk and producer risk. The method is illustrated and validated using a simulated example.
