Reliability modeling of degradation of products with multiple performance characteristics based on gamma processes
TL;DR: This paper proposes to use a bivariate Birnbaum–Saunders distribution and its marginal distributions to approximate the reliability function of a product that has two dependent performance characteristics and that their degradation can be modeled by gamma processes.
Journal ArticleDOI
Bivariate degradation analysis of products based on Wiener processes and copulas
TL;DR: In this paper, the authors consider a product with two performance characteristics and the degradation paths of these performance characteristics can be governed by a Wiener process with a time-scale transformation, and the dependency of the performance characteristics is described by a copula function.
Journal ArticleDOI
Bivariate Constant-Stress Accelerated Degradation Model and Inference
TL;DR: The Bayesian Markov chain Monte Carlo (MCMC) method is developed here for this model for obtaining the maximum likelihood estimates (MLEs) efficiently and a simulated example is presented along with the associated computational results.
Journal ArticleDOI
Multiple-Steps Step-Stress Accelerated Degradation Modeling Based on Wiener and Gamma Processes
TL;DR: The Bayesian Markov chain Monte Carlo (MCMC) method is applied for multiple-steps step-stress accelerated degradation models based on Wiener and gamma processes to obtain the maximum likelihood estimates (MLEs) efficiently and some computational results obtained from the implementation are presented.
Journal ArticleDOI
