Probabilistic evaluating the reliability of the control system of the unmanned aviation complex

The article proposes a method for estimating the reliability of the control system of an unmanned aerial system (UAS) with the help of Bayesian networks of trust (BNT). A method for constructing a BNT based on the unified modeling language (UML) diagrams used in the early stages of designing the UAS and its control system is described. It is shown that the construction of adequate BNT requires a detailed elaboration of the UAS UML-model for removing design uncertainties.
