Conference Proceeding
Andrews, J., & Tolo, S. (2022). Dynamic and Dependent Tree Theory (D 2 T 2 ): A Fault Tree Analysis Framework. In M. Chiara Leva, E. Patelli, L. Podofillini, & S. Wilson (Eds.), Book of Extended Abstracts for the 32nd European Safety and Reliability Conference (139-140)

A modelling framework, known as Dynamic and Dependent Tree Theory, is provided which overcomes restrictions in the Kinetic Tree Theory developed in the 1970s for the analysis of fault trees. Kinetic Tree Theory assumes basic events to be independent... Read More about Dynamic and Dependent Tree Theory (D 2 T 2 ): A Fault Tree Analysis Framework.

An Integrated Modelling Framework for Complex Systems Safety Analysis: Case-Studies (2022)
Conference Proceeding

The ever-increasing complexity of engineering systems has fuelled the need for novel and efficient computational tools able to enhance the accuracy of current modelling strategies for industrial systems. Indeed, traditional Fault and Event Tree techn... Read More about An Integrated Modelling Framework for Complex Systems Safety Analysis: Case-Studies.

A Petri Net approach to the Risk Analysis of Jet Engines (2022)
Conference Proceeding
Tolo, S., Andrews, J., Thatcher, I., & Stamp, D. (2022). A Petri Net approach to the Risk Analysis of Jet Engines. In M. Chiara Leva, E. Patelli, L. Podofillini, & S. Wilson (Eds.), Book of Extended Abstracts for the 32nd European Safety and Reliability Conference (137-138)

Traditional risk analysis techniques such as Fault Trees and Event Trees fail to model complex aspects of systems behaviour such as components dependencies, degradation, limiting their capability of representing modern engineering systems. This is al... Read More about A Petri Net approach to the Risk Analysis of Jet Engines.

Fault Tree analysis including component dependencies (2022)
Conference Proceeding
Tolo, S., & Andrews, J. (2022). Fault Tree analysis including component dependencies. In M. C. Leva, E. Patelli, L. Podofillini, & S. Wilson (Eds.), Book of Extended Abstracts for the 32nd European Safety and Reliability Conference (133-134). https://doi.org/10.1109/TR.2023.3264943

The inability of commonly used risk assessment methodologies to model component dependency is often recognised to be a barrier towards more realistic modelling of systems complexity. This is a significant limitation associated with widely adopted tec... Read More about Fault Tree analysis including component dependencies.
