Georgios Bakirtzis, Tim Sherburne, Stephen Adams, Barry M. Horowitz, Peter A. Beling, and Cody H. Fleming "An Ontological Metamodel for Cyber-Physical System Safety, Security, and Resilience Coengineering", Software & Systems Modeling (2021)
A representation of critical systems engineering concepts and their interrelationships spanning requirements, behavior, architecture, and test. This integrated model presents a high-level view of not only the ultimate specification of a system, but also the journey to that specification – concerns opened and closed, risks identified and managed.
