Fault Tree Analysis has been a cornerstone of safety-critical systems for many years. It has seen various extensions to enable it to analyse dynamic behaviours exhibited by modern systems with redundant components. However, none of these extended FTA...

Automatic optimisation of system architectures using EAST-ADL (2013)
Journal Article
Walker, M., Reiser, M., Tucci-Piergiovanni, S., Papadopoulos, Y., Lönn, H., Mraidha, C., …Servat, D. (2013). Automatic optimisation of system architectures using EAST-ADL. Journal of Systems and Software, 86(10), 2467-2487. https://doi.org/10.1016/j.jss.2013.04.001

There are many challenges which face designers of complex system architectures, particularly safety-critical or real-time systems. The introduction of Architecture Description Languages (ADLs) has helped to meet these challenges by consolidating info...

Assisted assignment of automotive safety requirements (2013)
Journal Article
Azevedo, L. D. S., Parker, D., Walker, M., Papadopoulos, Y., & Araújo, R. E. (2014). Assisted assignment of automotive safety requirements. IEEE Software, 31(1), 62-68. https://doi.org/10.1109/ms.2013.118

ISO 26262, a functional-safety standard, uses Automotive Safety Integrity Levels (ASILs) to assign safety requirements to automotive-system elements. System designers initially assign ASILs to system-level hazards and then allocate them to elements o... Read More about Assisted assignment of automotive safety requirements.
