- •
A generalized multivariate hybrid degradation process model is introduced.
- •
Various types of dependent degradation processes can be modeled coherently.

The effects of environmental conditions and operating profiles are investigated.
- •
Unit-specific RUL assessment is implemented through a two-step Bayesian method.
