Towards Smart Systems of Systems

Abstract

Abstract. Systems of Systems (SoS) have started to emerge as a consequence of the general trend toward the integration of beforehand isolated systems. To unleash the full potential, the contained systems must be able to operate as elements in open, dynamic, and deviating SoS architectures and to adapt to open and dynamic contexts while being developed, operated, evolved, and governed independently. We name the resulting advanced SoS to be smart as they must be self-adaptive at the level of the individual systems and self-organizing at the SoS level to cope with the emergent behavior at that level. In this paper we analyze the open challenges for the envisioned smart SoS. In addition, we discuss our ideas for tackling this vision with our SMARTSOS approach that employs open and adaptive collaborations and models at runtime. In particular, we focus on preliminary ideas for the construction and assurance of smart SoS.

Modeling Collaborations in Adaptive Systems of Systems

“…On the other hand, available domain specific software tools such as 4. 4 In general, a concrete realization of the Deurema models introduces additional refinements of the modeled behavior. For example, in a real physical system, virtual components must be deployed to existing execution capabilities.…”

“…Subsequently, the core, runtime model and domain concepts are used to describe the architecture of an adaptive SoS in Section 5. 4. The comprehensively capabilities of collaboration specifications between independent systems inside the SoS are introduced in Section 5.…”

“…Thus, runtime models define the amount of available knowledge within the system template specification as sketched in Figure 5. 4. Thereby, the Deurema approach supports the definition of local views for each behavioral entity placed on the layered system template specification.…”

“…In contrast, the adaptive light control module (ALC module instance) follows the component-based development paradigm as discussed in Section 5.3. 4. It has a timing trigger with a period of one second and runs independently from the other modules in the smart car architecture.…”

“…There are two lanes that specify the behavior of the follower and leader role of the platoon collaboration. 4 Each role behaves independently from the other roles with the exception of a message exchange. In the example, the follower role sends an Alive message directly after starting the interaction.…”
