How to Generate Fault Trees from Causal In uen e Diagrams

Development and Validation of a Comprehensive Hybrid Causal Model for Safety Assessment and Management of Aviation Systems

The United States Federal Aviation Administration (FAA) has initiated the development of a causal risk model of commercial air transport in support of the System Approach for Safety Oversight (SASO) program. The model uses the so-called Hybrid Causal Logic (HCL) methodology which combines Event Sequence Diagrams (ESD), fault trees (FT) and Bayesian Belief Networks (BBN). The model is hierarchic...

Sequence Algebra, Sequence Decision Diagrams and Dynamic Fault Trees

Dynamic Fault Trees have focused a large attention in the past few years. By adding new gates to static (regular) Fault Trees, Dynamic Fault Trees aim to take into account the order in which events occur. Lesage & al. proposed recently an algebraic framework to give a formal interpretation to these gates. In this article, we extend Lesage’s work by adopting a slightly different perspective. We ...

Incorporating human and organizational factors in risk analysis for offshore installations

This paper presents a methodology for quantitative risk analysis on oil and gas production platforms that incorporates both technical and operational conditions. The basic building blocks of the methodology are barrier block diagrams, event trees, fault trees, and influence diagrams. Barrier block diagrams are used to illustrate the event scenarios and the effect of barrier systems on the scena...
