Szukana fraza: [Abstract = "To achieve the formulation of the reliability model, Bayesian estimation of Weibull parameters and the model\?s goodness\-of\-fit are evoked. The advantages of this modelling approach are presented in the case of systems with an unknown reliability structure, those with a common cause of failures and redundant ones. Finally, we raise the issue of the use of BNs in the fault diagnosis area."]
