Let’s provide the sequence of actions necessary for creating a model in the form of the network, methods for computing a probabilistic output in BN, and give examples of using the tool to solve practical problems of operational financial risk estimation. The study results can be used by financial institutions as a tool for resolving specific practical issues of risk estimation.</p> <p><strong>The object of research:</strong> methods for constructing Bayesian Networks for modeling operational risk in financial institutions.</p> <p><strong>Investigated problem:</strong> modeling operational risk under conditions of uncertainty.</p> <p><strong>The main scientific results:</strong> overview of methods for constructing Bayesian Networks for modeling operational risk under conditions of uncertainty; the methodology in the form of sequence of actions necessary for creating the model in the form of the network; methods for computing a probabilistic output in BN; examples of applying such approaches to solve practical problems of operational financial risk estimation.</p> <p><strong>The area of practical use of the research results:</strong> The research results can be used in the following financial institutions: banking system, insurance and investment companies.</p> <p><em><strong>Innovative technological product:</strong></em><em> computer based decision support system, allowing for high quality modeling and estimation of operational risks. </em></p> <p><strong>Scope of the innovative technological product</strong>: the practice of usage the proposed models in financial organizations provides an evidence of their high efficiency in terms of formal description and estimation of operational risk</p&gt;}, number={2}, journal={ScienceRise}, author={Levenchuk, Liudmyla}, year={2022}, month={Apr.}, pages={11-20} }
