“…These information can be evaluated using the RUL probability distribution. However, in literature, this distribution is obtained primarily based on the assumption about the degradation modeling [31][32][33][34]. In reality, especially in the case of complex systems with multiple sensor sources, it is not easy to derive the underlying degradation model.…”

“…Even if theoretical models can be built, for some stochastic deterioration processes, the RUL distribution cannot be directly obtained with the analytical approaches. The RUL estimation in these cases has to be based on the simulation techniques that could be difficult to be used in real time applications [31,32]. To overcome this situation, we present in this section a new data-driven prognostic method that directly provides the probability of the system failure without prior knowledge of the failure mechanism.…”

“…Although various kinds of model-selection criteria have been proposed, such as minimum description length [15], Akaike information criterion [16], Bayesian information criterion [12], and empirical average log-likelihood, current model-selection criteria are not comprehensive. Usually, they primarily consider the sampling errors in parameter estimation [17]. Indeed, owing to indistinct degradation characteristics and insufficient selection criteria, a fixed degradation model may be unscientific, especially for real-time RUL prediction with incomplete degradation trajectory.…”

“…Many scholars [ 2 , 3 , 4 , 5 , 6 , 7 ] have conducted extensive research on health status prediction. For example, Nguyen et al studied the selection of different degradation models using a large number of health monitoring data [ 8 ]. Most of the systems for health status prediction have been modeled based on one of several approaches: the gamma process [ 9 , 10 , 11 ], Wiener process [ 12 , 13 ], Markov process [ 14 ], general generation function [ 15 ], Monte Carlo Simulation [ 16 , 17 , 18 ].…”
