Influence strategies for systems of systems
… decision making has been identified as a source of managerial complexity for leaders of systems of systems (SoS). A new framework, AIR (Anticipation-Influence-Reaction), is proposed to capture the feedback relationships between the decisions made by constituents and those made by the managers of …

Multiobjective collaborative optimization of systems of systems
… However, warships generally operate as part of a larger battle or strike group. Therefore, the designs should be evaluated as part of a system of multiple ship systems since designing each ship individually may result in underutilized and excess equipment and capability; in other words an …

Modeling collaborations in adaptive systems of systems
… and flexibility, beforehand isolated systems have become interconnected to gain powerful adaptive Systems of Systems (SoS) solutions with an overall robust, flexible and emergent behavior. The adaptive SoS comprises a variety of different system types ranging from small embedded to …

Security risk assessment in systems of systems.
A System of Systems (SoS) is a set of independent systems that interoperate to achieve capabilities that none of the separate systems can achieve independently. The component systems may be independently operated or managed, and this may cause control problems. An area of particular concern is …

Investigating Army systems and Systems of Systems for value robustness
… a value robustness approach to architect defense systems and Systems of Systems (SoS). A value robust system or SoS has the ability to provide continued value to stakeholders by performing well to meet the mission intent under a variety of future contexts. The proposed approach encompasses three …

A scalable methodology for modeling cities as systems of systems
… evolve in size and complexity, their component systems become more interconnected. Comprehensive modeling and simulation is needed to capture interactions and correctly assess the impact of changes. This thesis presents a methodology for modeling cities from a systems of systems perspective. The …

Acquisition strategies for commonality across complex aerospace systems-of-systems
… used to improve affordability and reliability of families of products. However not all commonality is beneficial, and organizations must balance commonality benefits and commonality costs to pursue a successful strategy. The existing literature on commonality assumes that all commonality …

System importance measures: A new approach to resilient systems-of-systems
… While this attribute has been the focus of research in several fields, in the case of system-of-systems (SoSs), addressing resilience is particularly interesting and challenging. As infrastructure SoSs, such as power, transportation, and communication networks, grow in complexity and …

Architectural modelling and verification of open service-oriented systems of systems
Systems of Systems (SoS) have received a lot of attention recently. In this thesis we will focus on SoS that are built atop the techniques of Service-Oriented Architectures and thus combine the benefits and challenges of both paradigms. For this thesis we will understand SoS as ensembles of single …

A cost model for testing unmanned and autonomous systems of systems
The evolutionary nature of Unmanned and Autonomous Systems of Systems (UASoS) acquisition needs to be matched by equally evolutionary test capabilities in the future. There is currently no standard method to determine what is required to make programs safe for deployment, nor is there the ability …

A New Method for the Examination of Policy Systems of Systems
… policy environments as a policy system of systems (SoS). The research conducted for this dissertation establishes the need to develop a method of analysis suitable for the analysis of a policy SoS that allows for the examination of individual policy relationships while maintaining a …

A reliability-based measurement of interoperability for conceptual-level systems of systems
The increasing complexity of net-centric warfare requires assets to cooperate to achieve mission success. Such cooperation requires the integration of many heterogeneous systems into an interoperable system-of-systems (SoS). Interoperability can be considered a metric of an architecture, and must …

Identifying and Mitigating Security Risks in Multi-Level Systems-of-Systems Environments
… governments, and cities have taken advantage of the many benefits and automated processes Information and Communication Technology (ICT) offers, evolving their existing systems and infrastructures into highly connected and complex Systems-of-Systems (SoS). These infrastructures endeavour to …

Transforming the DoD test and evaluation enterprise to enable unmanned autonomous systems of systems
Many US Department of Defense (DoD) systems operate within a systems of systems construct, which present many challenges and will be ever increasing for test and evaluation of unmanned autonomous systems of systems. Challenges include emergent behaviors along with resource limitations that will …

A methodology for the robustness-based evaluation of systems-of-systems alternatives using regret analysis
After surveying the state-of-the-art in evaluation of alternatives in the defense acquisition process, a methodology for the evaluation of the robustness of systems-of-systems alternatives was proposed. In the methodology, robustness is defined as the integral of the alternative s regret over the …
