Dynamic safety analysis of process systems by mapping bow-tie into Bayesian network
TL;DR: This paper introduces the application of probability adapting in dynamic safety analysis rather than probability updating, and illustrates how Bayesian network (BN) helps to overcome limitations in BT.

Quantitative risk analysis of offshore drilling operations: A Bayesian approach
TL;DR: The Bayesian network method provides greater value than the bow-tie model since it can consider common cause failures and conditional dependencies along with performing probability updating and sequential learning using accident precursors.
Journal ArticleDOI
Dynamic risk analysis using bow-tie approach
TL;DR: This work is focused on using bow-tie model approach in a dynamic environment in which the occurrence probability of accident consequences changes, and uses Bayes’ theorem to estimate the posterior probability of the consequences which results in an updated risk profile.

Fuzzy logic for process safety analysis
TL;DR: This paper explores the application of fuzzy sets theory for basic tools used in process safety analysis such as fault and event tree methods which can be further used in the “bow-tie” approach for accident scenario risk assessment.

Radyban: A tool for reliability analysis of dynamic fault trees through conversion into dynamic Bayesian networks
TL;DR: Radyban (Reliability Analysis with DYnamic BAyesian Networks), a software tool which allows to analyze a dynamic fault tree relying on its conversion into a dynamic Bayesian network, and compares the unreliability results it generates with those returned by other methodologies, to verify the correctness and the consistency of the results obtained.
