Systems of Systems (SoS) are a current focus of many organizations interested in integrating assets and utilizing new technology to create multi-component systems that deliver value over time. The dynamic composition of SoS along with the managerial independence of their component systems necessitates systems engineering considerations and methods beyond those of traditional systems engineering...

As organizations strive to expand system capabilities through the development of system-ofsystems (SoS) architectures, they want to know “how much effort” and “how long.” In order to answer these questions, it is important to first understand the types of activities performed in SoS architecture development and integration and how these vary across different SoS implementations. This paper prov...

Acquisition of a system of systems can be an all new acquisition of multiple systems that are intended to operate together as a system-of-systems. Much more common in the DoD is acquisition of one or more new systems that are intended to interoperate with existing systems as a system of systems with new capabilities. In either case, successful acquisition of systems-of-systems (SoS) necessarily...

System of Systems (SoS) development is a complex process that depends on the cooperation of various independent Systems [1]. SoS acquisition and development differs from that typical for a single System; it has been shown to follow a wave paradigm known as the Wave Model [2]. Agent based models (ABMs) consist of a set of abstracted entities referred to as agents, and a framework using simplifie...

When you create a System of Systems (SoS), you are doing wilful design. It follows that you need a safety case: a justification of why that system will be safe. All safety cases must have certain common properties: they must focus on risk, they must provide appropriate confidence in their claims, and they must have a clear relationship to a causal model of the system's safety behaviour. None of...

Many qualitative descriptions of Systems of Systems (SoS) exist in the literature, but only heuristics and guiding principles have been suggested with regard to SoS design methods. To assist SoS designers in decision making during conceptual design, prescriptive design methods are required for SoS. To develop a SoS design method, we propose to build on an existing system tradespace exploration ...

The modern personal computer is capable of executing many millions of instructions per second. Some of these instructions may cause the computer to slow down, expose security vulnerabilities to the outside world, or cause other undesirable behavior. It is impractical and unwieldy to regularly probe the operating system’s kernel and analyze enormous text files for detecting anomalous behavior. Y...

To support safe self-movement of the disabled and the aged, we developed an electric wheelchair that realizes the functions of detecting both the potential hazards in a moving environment and the postures and gestures of a user by equipping an electric wheelchair with the stereo omnidirectional system (SOS), which is capable of acquiring omnidirectional color image sequences and range data simu...

The cutting edge in systems development today is in the area of systems of systems, (SoS) large networks of inter-related systems that are developed and managed separately, but that also perform collective activities. Such large systems typically involve constituent systems operating with different life cycles, often with uncoordinated evolution. The result is an ever-changing SoS in which adap...

System of Systems (SoS) is a new class of complex software systems resulting from the integration of several independent systems working together. Within a SoS, many participant systems may be integrated and deleted operationally over the time. Each system has an Architecture Model modeled at design time. Thus, the SoS’ software architecture description is represented by an aggregated Architect...
