Evidential Networks for Evaluating Predictive Reliability of Mechatronics Systems under Epistemic Uncertainties
2019
Journal of KONBiN
Preserved Fulltext
complex systems with high-reliability precision such as mechatronic systems, uncertainties are inevitable and must be considered in order to predict with a degree of confidence the evaluated reliability ...
The key point in this study is to use an Evidential Network "EN" based on belief functions and the dynamic Bayesian network. ...
Later on, Duy [16] used belief functions in the form of p-boxes along with Monte-Carlo simulations to model propagation of uncertainty. ...
