“…Subsequently, the TSS was modified and extended to incorporate HHM [Kaplan, Haimes, and Garrick, 2001]. Chittester and Haimes [2004] present a detailed discussion of the sources of risk to a supervisory control and data acquisition (SCADA) system used by railways and identified through HHM. The vulnerabilities of SCADA CIS to terrorist attacks were explored through three major perspective categories: (i) hardware and software; (ii) human supervisory; and (iii) the system's environment.…”

Building on systems-based philosophy, theory, methodology, and practice, the challenges associated with modeling, assessing, managing, and communicating the multidimensional risk to cyberinfrastructure systems (CIS) serviced by cloud computing technology (CCT) as systems of systems (SoS) are explored. The article raises concerns about the euphoria in the literature about CCT and stresses the importance of understanding the complex process of modeling, assessing, managing, and communicating the risks associated with CIS-CCT. Several themes are highlighted: the theory of scenario structuring; the epistemology of the states of the CIS-CCT systems; the role of systems integration in CIS-CCT; the risk to CIS-CCT from malicious insiders' intrusion; the complex definition and quantification of the risk function associated with CIS-CCT systems; and modeling the multiple perspectives of CIS-CCT, focusing on hierarchical holographic modeling (HHM) and phantom system models (PSM). The paper concludes with an epilogue and list of references.

“…The influence of these events on the modeling literature is twofold. First, there is an increased awareness of the need for interdisciplinary approaches that consider a broader range of factors and systems in vulnerability modeling so that new causal mechanisms, interdependencies, and socio-technical responses are considered [Chittister and Haimes, 2004;Cutter, Richardson and Wilbanks, 2003]. Secondly, the need to implement systems approaches and systems-of-systems approaches has been suggested as a means to manage the extreme complexity inherent in the wider problem scope [Jain and McLean, 2003;Little, 2004;Rinaldi, 2004].…”

Human socio-technical systems are particularly vulnerable to natural and manmade disasters that project vast physical effects on interdependent functional infrastructure. Many disciplines are trying to understand the complex interactions between the physical world and the systems at risk within it. Systems engineering design is directly concerned with relationships between requirements, functions, and the physical architecture that implements functions. This paper explores the use and advantages of systems engineering design modeling that has been made sensitive to the spatial effects of the physical world by using a geographic information system (GIS) to represent elements of the physical architecture. The paper begins with a description of the spatial context and geographic information systems technology. We review how the spatial context is presently manifested in systems engineering and design modeling and then describe how we combined a geospatial model with a systems engineering design model and explored the unique views that the combined conceptual models introduce. We present a process approach developed for the natural hazard vulnerability domain and discuss our findings to date and the challenges that resulted from mixing models of greatly different fidelity. We conclude by suggesting future work that is needed to further investigate
