Safety analysis is an essential part of the development process of complex systems. However, decisions that are based on flawed safety assessment models, or models used beyond their envelope of validity can negatively impact safety design choices, the effectiveness of certification, and operational practice. Therefore, the justification of assumptions, data sources and analytical methods is necessary...
The term Systems of Systems (SoS) has recently been introduced in the systems engineering domain to describe a new class of systems, exhibiting a number of attributes such as complexity, autonomy, and geographic dispersion. The (UK) Ministry of Defence Architectural Framework (MODAF) is a prominent framework used in the defence domain. MODAF is organised in views, each of which focuses on a single...
Analyzing accidents is a vital exercise in the development of safety-critical software systems to prevent past accidents from reoccurring in the future. Current practices such as causal event analysis are insufficient in light of a growing trend of accidents involving complex interactions between components with and without the occurrence of failures. Furthermore, the reuse of accident knowledge in...
