Analysing the impact of local factors on the life cycle of metallic bridge girders (2023)
Conference Proceeding
Calvert, G., Hamer, M., Neves, L., & Andrews, J. (2023). Analysing the impact of local factors on the life cycle of metallic bridge girders. In F. Biondini, & D. M. Frangopol (Eds.), Life-Cycle of Structures and Infrastructure Systems: PROCEEDINGS OF THE EIGHTH INTERNATIONAL SYMPOSIUM ON LIFE-CYCLE CIVIL ENGINEERING (IALCCE 2023), 2-6 JULY, 2023, POLITECNICO DI MILANO, MILAN, ITALY

A fundamental component of a life cycle analysis of a bridge is the modelling of asset condition post-construction. To enhance the accuracy of bridge deterioration models, several studies have calibrated models based on cohorts that incorporate struc...

Fault Tree analysis is not only the most common technique used in engineering practice for the estimation of system reliability, but is also a key tool shared between designers, analysts and regulators for safe operation and licensing purposes. In sp... Read More about Fault Tree Analysis Including Component Dependencies.

Dependent and Dynamic Tree Theory (D2T2 ) for Event Tree Applications (2023)
Presentation / Conference
Tolo, S., & Andrews, J. (2023, April). Dependent and Dynamic Tree Theory (D2T2 ) for Event Tree Applications. Presented at 62nd ESReDA Seminar, University of Twente, the Netherlands

The demand for innovative and effective computational tools able to improve the accuracy of present modelling methodologies has been fuelled by the ever-increasing complexity of engineering systems. In spite of their shortcomings, such as their inabi... Read More about Dependent and Dynamic Tree Theory (D2T2 ) for Event Tree Applications.

Extension of Common Measures of Importance for Dynamic and Dependent Tree Theory (D2T2 ) (2023)
Presentation / Conference
Lunt, S., & Andrews, J. (2023, April). Extension of Common Measures of Importance for Dynamic and Dependent Tree Theory (D2T2 ). Presented at 62nd ESReDA Seminar, University of Twente, the Netherlands

Traditional Fault Tree Analysis (FTA), known as Kinetic Tree Theory (KTT), was derived by Vesely [1] to model and analyse engineering systems. The tree structure provides a clear visual representation of the causes of system failure in terms of compo...

Dynamic safety and degradation analysis of an aircraft internal air system (2023)
Presentation / Conference
Tolo, S., Andrews, J., Thatcher, I., & Stamp, D. (2023, April). Dynamic safety and degradation analysis of an aircraft internal air system. Presented at 62nd ESReDA Seminar, University of Twente, the Netherlands

The modelling of the dynamic behaviour of engineering systems offers an invaluable insight in the evolution of degradation and response of systems to failure and represents an essential step to lay the basis for resilience analysis. While traditional... Read More about Dynamic safety and degradation analysis of an aircraft internal air system.

The Dynamic and Dependent Tree Theory (D2T2 ) methodology Developed for Fault Tree Analysis (2023)
Presentation / Conference
Andrews, J., & Tolo, S. (2023, April). The Dynamic and Dependent Tree Theory (D2T2 ) methodology Developed for Fault Tree Analysis. Presented at 62nd ESReDA Seminar, University of Twente, the Netherlands

Fault Tree Analysis (FTA) has its origins back in the 1960’s with the mathematical framework, known as Kinetic Tree Theory (KTT) added at the end of the decade by Vesely. In KTT the analysis of the fault tree is performed in two stages. The first sta... Read More about The Dynamic and Dependent Tree Theory (D2T2 ) methodology Developed for Fault Tree Analysis.
