“…50 Furthermore, additional support from appropriate technical and programmatically inclined system engineers from within the DoD can be of value here as well. Several key efforts organizations have developed tools for early lifecycle architectural assessments for this purpose, 45,46 In this example problem, we adopt a tool called the Fractionated Satellite Design Space Exploration Toolbox (FSDSET). 47 This tool allows the user to specify the ''component ecosystem,'' which is a library of components, their interface specifications, and design rules for connecting these components.…”

The US Department of Defense’s acquisition strategy incorporates directives to encourage the use of open architectures and modular solutions through the Modular Open Systems Approach (MOSA). The ways in which open standards are currently implemented, and programmatic guidance regarding the adoption of modular approaches, are inadequate, however, because of limitations on how modularity is objectively viewed to achieve its perceived benefits. Furthermore, current examples of implementations of modular concepts largely do not consider interdependencies at the enterprise level. This paper reviews ongoing research on modularity and openness, to synthesize best practices, community driven knowledge, and technical and programmatic catalysts that can better shape the appropriate adoption of MOSA. These items will be part of a comprehensive decision-making framework that can provide guidance to program managers in defense acquisition.

“…Motivated by considerations on the nature of SoS, in previous research we have developed an SoS Analytic Work Bench, a suite of methods and tools that can be used to achieve the needed top-level systemic assessment touching different aspects of SoS engineering. 10 The suite includes tools that can deal with the operational aspects of complex architectures. Some of these methodologies have already been applied to the modeling and analysis of demonstration problems.…”

Dynamic and real-time adaptive configuration of Cyber-Physical Systems (CPSs) results in increased complexity due to a variety of heterogeneous and interdependent variables and creates unique challenges. For example, 1) Emergent Behavior: How do we ensure that system constituents dynamically and adaptively collaborate to produce a consistent repeatable functionality while supporting the capability to upgrade the individual entities through technology infusion; 2) Scale: How do we ensure scalability of these systems by managing complexity; 3) Risk Management: How do we evaluate and manage the risks associated with the connection and interdependencies of heterogenous systems.Design and development of this new generation of CPSs can be viewed through the lens of System-of-Systems (SoS) methodology which is designed to analyze and assess the evolving topologies created by interactions within a large complex system operating in dynamic and uncertain environment. In this paper, we propose the use of several SoS tools and techniques for the analysis and design of nextgeneration CPSs. Our SoS methodologies address features such as diversity of component systems, complex hierarchical structures, dynamic and emergent behavior, and interactions between components. Therefore, they are suitable to treat some of the challenging features of cyber-physical systems. However, it is necessary to modify these methodologies to address specific aspects of CPSs. Constraints and metrics from SoS methodology, applied to the design space, will support decision on component systems and the topology of their connections, and provide a set of -good designs‖, with desired characteristics.

“…Davendralingam et al argued that the process of evolving SoS architectures “requires tools that provide the SoS practitioner with meaningful analytical quantifications of the SoS trade space.” In the defense context, existing tools that can be used for such trades have been guided by policies (such as published by the Department of Defense), yet are lacking an “analytic perspective towards more informed decision‐making.” Their work was “motivated by the idea that SoS practitioners possess relevant information and archetypal questions that reflect desired outcomes at the SoS level. These archetypal, technically‐driven queries are mapped to relevant methods that can provide analytical outputs to directly support SoS acquisition and architectural decisions.” 18 …”

Increasingly complex systems of systems (SoS) have to be developed in ever shorter times-tomarket at reduced costs and with high reliability. In addition, as the life cycle of such SoS frequently spans across several decades, customer expectations and market conditions will evolve. Systems engineering (SE)/model-based systems engineering (MBSE) and configuration management (CM) need to be ever more closely integrated to appropriately address this situation. CM as a discipline is essential for establishing traceability and controlling baseline evolutions between all the relevant pieces of information resulting from the related system life cycle processes of all constituent systems of such SoS; but for this to work, the scope of CM must be extended both throughout the entire life cycle and across all participating monolithic systems. New frameworks are needed to effectively and efficiently apply CM across SoS arrangements. This paper proposes an ontologybased, federative approach to managing the inherent complexity of CM in the context of SoS, with particular focus on a change management framework for SoS. Examples from a conceptual system that is concerned with the submarine exploration of Enceladus as part of the "Saturn exploration system" are used to demonstrate typical SE/MBSE artifacts and how CM needs to address them across the involved operational and enabling systems.
