system-level-RUL uncertainty

System-level RUL (Remaining Useful Life) uncertainty refers to the uncertainty surrounding the estimate of the remaining useful life of a system. This uncertainty arises due to various factors such as incomplete knowledge about the system's degradation mechanisms, variability in operating conditions, measurement errors, and model inaccuracies. System-level RUL uncertainty can be quantified using probabilistic methods such as Bayesian inference and Monte Carlo simulations. Accurate estimation of system-level RUL uncertainty is crucial for effective maintenance planning and decision-making to ensure the safe and reliable operation of systems.
