“…Any CI is an instance of a system of systems (SoS) (Jamshidi, 2010;Sousa-Poza et al, 2008;Gorod et al, 2008). While regular complex IT systems still got boundaries and defined architecture, a SoS is blurrier in boundaries and may evolve in time (Giannopoulos et al, 2012).…”

This paper applies research in dependency modelling to a process-based risk assessment methodology suitable for critical infrastructures. The proposed methodology dynamically assesses the evolution of cascading failures over time between assets involved in a business process of an infrastructure. This approach can be applied by a CI operator/owner to explore how a failure in a single component (asset) affects the other assets and relevant business processes. It could also be applied in an analysis that includes multiple CI operators in the same supply chain to explore the dependencies between their assets and explore how these affect the provision of key societal services. The paper presents a proof-of-concept tool, based on business-process risk assessment and graph modelling, and a realistic case example of a rail scheduling process. The approach allows risk assessors and decision makers to analyse and identify critical dependency chains and it can reveal underestimated risks due to dependencies.Keywords: risk assessment; business process; asset; dependency; cascading failures; risk chains; likelihood; impact; critical infrastructure.

“…The internal complex system of systems (SOS) is a collection of collaborative systems bonded together under defined rules and regulations with the goal of exhibiting the complex properties of living systems (Boardman et al, 2006;Gorod et al, 2008;Di Mario et al, 2009). In this context, each individual, has a component structure of a "1" or "0" decision nodes which lead to action/inaction which in turn exerts its resultant influence on the overall SOS.…”

It is postulated in this research that the paradox of "advances in technology and management not keeping pace with the ever-increasing urban problems" is due to the poor understanding of person-focused governance of societal, environmental and economic entities. Therefore, the objective of this paper is to present an adaptive institutional model of person-driven effectiveness and ineffectiveness. The model proposes that human, ecologic and economic outcomes are heavily influenced by a complex system of systems, spanning from individually unique "non-physical influencers" to a broader set of social and environmental influencers that have a common impact on the larger society-environmenteconomy (SEE) system. At the heart of the model is an analytic formulation that explains the phenomena of non-physical blocker, enhancer and indifferent that are responsible for the adaptation and maladaptation of social agents, and accordingly for the sustainability and unsustainability of SEE systems. Examples are provided to illustrate the model applications: (a) the non-physical and maladaptive syndromes as antecedents of multimorbidity and (b) the broadened and narrowed minds as sources of sustainability and unsustainability at the SEE system level within the context of emerging technologies such as engineered nanomaterials.

“…The concept of system-of-systems (SoS) was first brought up in Boulding's work [1] in 1956, but it was not until 1989, with the Strategic Defense Initiative, that SoS was introduced to engineering application [2,3]. Although this field has been growing significantly in recent years [4], it is still in the primary stage without a common definition [5][6][7].…”

Design space exploration has been much neglected in aircraft conceptual design phase, which often leads to a waste of time and cost in design, manufacture and operation process. It is necessary to explore design space based on operational systemof-systems (SoS) simulation during the early phase for a competitive design. This paper proposes a methodology to analyze aircraft performance parameters in four steps: combination of parameters, object analysis, operational simulation, and keyparameters analysis. Meanwhile, the design space of an unmanned aerial vehicle applied in earthquake search and rescue SoS is explored based on this methodology. The results show that applying SoS simulation into design phase has important reference value for designers on aircraft conceptual design.
