报告摘要：Degradation analysis has been an attractive approach to reliability assessment for highly reliable products. This presentation will discuss some case studies on degradation modeling and analysis. In the first case study, products exhibited multi-phase degradation patterns, and a change-point regression model was used to model the nonlinear degradation phenomenon. In the second case study, units came from a nonhomogeneous population, and a Gaussian mixture model was used to model the excessive unit-to-unit variability in degradation paths. Finally, a degradation-based burn-in optimization problem will be discussed.
