TY - JOUR PY - 2017// TI - A flexible hierarchical Bayesian modeling technique for risk analysis of major accidents JO - Risk analysis A1 - Yu, Hongyang A1 - Khan, Faisal A1 - Veitch, Brian SP - 1668 EP - 1682 VL - 37 IS - 9 N2 - Safety analysis of rare events with potentially catastrophic consequences is challenged by data scarcity and uncertainty. Traditional causation-based approaches, such as fault tree and event tree (used to model rare event), suffer from a number of weaknesses. These include the static structure of the event causation, lack of event occurrence data, and need for reliable prior information. In this study, a new hierarchical Bayesian modeling based technique is proposed to overcome these drawbacks. The proposed technique can be used as a flexible technique for risk analysis of major accidents. It enables both forward and backward analysis in quantitative reasoning and the treatment of interdependence among the model parameters. Source-to-source variability in data sources is also taken into account through a robust probabilistic safety analysis. The applicability of the proposed technique has been demonstrated through a case study in marine and offshore industry.
