A Stochastic Methodology for Prognostics Under Time-Varying Environmental Future Profiles

• Most failures of engineering systems result from the gradual and irreversible accumulation of damage: – A process known as Degradation • We examine degradation processes that can be monitored using sensor technology and that result in – Degradation Signals • We focus on – Modeling degradation signals under time-varying environmental conditions. – Computing the distribution of residual life under deterministic time-varying future environments.
