A Service-Oriented System of System (or SoS) considers system as a service and constructs a value-added SoS by outsourcing external systems through service composition. To cope with the dynamic and uncertain running environment and assure the overall Quality of Service (or QoS), online reliability prediction for SoS arises as a grand challenge in SoS research. Online reliability prediction is e...

The US aircraft carrier formation is a complex system-of -systems (SoS). Taking the logistics support organization system of U.S. as an example, scientific management SoS discussed in this paper. Through detailed discussion and analysis command relationship organization, well responsibility its various agencies, mode are discussed. characteristics summarized detail.

The Constructive System-of-Systems (SoS) Integration Cost Model (COSOSIMO) is designed to estimate the effort associated with the Lead System Integrator (LSI) activities to define the SoS architecture, identify sources to either supply or develop the required SoS component systems, and eventually integrate and test these high level component systems. For the purposes of this cost model, an SoS ...

System-of-systems (SoS) architectures based on common software platforms have been commercially successful. Common platforms are a goal of several DoD initiatives (US Army Common Operating Environment, US Navy Open Architecture, multi-service Future Avionics Capability Environment), but progress on creating and adopting such platforms has been slow. We conducted a study to understand the techni...

This paper builds on and extends U.S. Department of Defense published guidance on systems engineering (SE) of systems of systems (SoS) by developing and presenting a view of SoS SE that translates the SoS SE core elements, their interrelationships, and SoS decision-making artifacts and information from a “trapeze” model to a more familiar and intuitive time-sequenced “wave” model representation...

The Customs and Border Protection (CBP) organization must secure the homeland by preventing illegal entry into the United States. In order to successfully accomplish this task, a System of Systems (SoS) of airborne, ground, fixed, mobile, manned, and unmanned capabilities must act together in order to successfully accomplish the objective. However, it may be difficult to identify a specific SoS...

This paper considers the rigorous design of Systems of Systems (SoS), i.e. systems composed of a set of heterogeneous components whose number evolves with time. Such components cooperate to accomplish functions that they could not achieve in isolation. Examples of SoS include smart cities or airport management system. The dynamical evolution of SoS behavior and architecture makes it impossible ...

One of the key issues facing architects of systems of systems (SOS) is the emergent nature of the context of the SOS. In the spirit of Herbert Simon, context here means all the stakeholders, objects, processes and other external effects that create the environment for goal attainment of a system. As SOS are systems, they too have contexts. Understanding the relationship between the contexts of ...

System-of-Systems (SoS) have been considered the new trend of software systems for several reasons, such as the advancement of computer technology and the increasing complexity and size of the systems. The concept of SoS has the central idea of a set of operationally independent software systems that collaborate together to compose a larger and more complex system. For SoS, several quality attr...

For any safety-critical system, thorough and complete hazard analysis must be performed if the system is to be acceptably safe to operate. For the emerging class of systems known as Systems of Systems (SoS), however, performing hazard analysis is extremely difficult because of the complexity of SoS and the environments they inhabit. Traditional exploratory hazard analysis techniques commonly re...
