Bivariate and two-phase degradation modeling and reliability analysis with random effects
Bivariate and two-phase degradation modeling and reliability analysis with random effects
The paper aims at predicting the remaining useful life of highly reliable and long-life products with multiple and multi-stage characteristics in the degradation process. Considering the unit-to-unit variability among the product units, a new bivariate and two-phase Wiener process model with random effects is established. Schwarz Information Criterion is used …
