An efficient real-time method of analysis for non-coherent fault trees (2009)
Journal Article
Remenyte-Prescott, R., & Andrews, J. (2009). An efficient real-time method of analysis for non-coherent fault trees. Quality and Reliability Engineering International, 25(2), https://doi.org/10.1002/qre.955

Fault tree analysis is commonly used to assess the reliability of potentially hazardous industrial systems. The type of logic is usually restricted to AND and OR gates which makes the fault tree structure coherent. In non-coherent structures not only...

Analysis of non-coherent fault trees using ternary decision diagrams (2008)
Journal Article
Remenyte-Prescott, R., & Andrews, J. (2008). Analysis of non-coherent fault trees using ternary decision diagrams. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 222(2), https://doi.org/10.1243/1748006XJRR154

Risk and safety assessments performed on potentially hazardous industrial systems commonly utilise Fault Tree Analysis (FTA) to forecast the probability of system failure. The type of logic for the top event is usually limited to AND and OR gates whi... Read More about Analysis of non-coherent fault trees using ternary decision diagrams.

An enhanced component connection method for conversion of fault trees to binary decision diagrams (2008)
Journal Article
Remenyte-Prescott, R., & Andrews, J. (2008). An enhanced component connection method for conversion of fault trees to binary decision diagrams. Reliability Engineering and System Safety, 93(10), https://doi.org/10.1016/j.ress.2007.09.001

Fault Tree Analysis (FTA) is widely applied to assess the failure probability of industrial systems. Many computer packages are available which are based on conventional Kinetic Tree Theory methods. When dealing with large (possibly non-coherent) fau... Read More about An enhanced component connection method for conversion of fault trees to binary decision diagrams.

Prime implicants for modularised non-coherent fault trees using binary decision diagrams (2007)
Journal Article
Remenyte-Prescott, R., & Andrews, J. (2007). Prime implicants for modularised non-coherent fault trees using binary decision diagrams. International Journal of Reliability and Safety, 1(4), https://doi.org/10.1504/IJRS.2007.016259

This paper presents an extended strategy for the analysis of complex fault trees. The method utilises simplification rules, which are applied to the fault tree to reduce it to a series of smaller subtrees, whose solution is equivalent to the original...

Qualitative analysis of complex modularized fault trees using binary decision diagrams (2006)
Journal Article
Remenyte-Prescott, R., & Andrews, J. (2006). Qualitative analysis of complex modularized fault trees using binary decision diagrams. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 220(1), https://doi.org/10.1243/1748006XJRR10

Fault tree analysis is commonly used in the reliability assessment of industrial systems. When complex systems are studied conventional methods can become computationally intensive and require the use of approximations. This leads to inaccuracies in...
