Developing fuzzy logic strength of evidence index and application in Bayesian networks for system risk management
作者:
Highlights:
• A fuzzy SoE (strength of evidence) index is developed based on fuzzy logic theory.
• The ambiguity issue of SoE raised in the literature in risk analysis is tackled.
• Full digitalization of all elements in risk RC,P,SoEBK) is enabled.
• The integration of fuzzy SoE index to BNs (Bayesian networks) is demonstrated.
• Their integrated features showcase an improved system risk management approach.
