The level of complexity in Systems of Systems is increasing as more complex functionality emerges from the interaction of individual components. As networks become more complex it becomes more difficult for an individual to identify potential safety risks. We know, from previous accidents, that poor understanding of networks can be dangerous. In this paper, we demonstrate the potential value of incorporating...
Impact of globalization, technological and environmental changes, has radically influenced supply chain risks and mitigating strategies. Since uncertainty is an intrinsic element of the aerospace supply chain system, this paper analyses the uncertain variables (risks) in aerospace supply chain using a `systems of systems' approach. Complexity and interdependent nature of the aerospace supply chain...
As one can only reason about the safety of software within the system context in which the software is executing, traditional independent validation and verification approaches which focus on the assurance of satisfaction of requirements by the delivered software are not sufficient in the assurance of software safety requirements. This paper presents an extension to an approach to assurance that relies...
Systems Engineering is used to develop systems to provide capability. Due to its heritage of being used to deal with large, complex and often unprecedented systems, there is perhaps a tendency for what might be called `traditional' approaches to involve long and costly development programmes. However, there are many challenges that would benefit from the rigour of Systems Engineering that require...
The Through Life Capability Management (TLCM) construct, currently being embraced by defense departments across the globe, is a commercial and social endeavor that requires a multitude of socio-technical systems to work together effectively in a system of systems. TLCM demands changes in the organization and culture of the defense supply chain in ways that fly in the face of traditional commercial...
