Extending the Concept of Domain Specific Systems Engineering to System-of-Systems

With the ongoing evolution of cyber-physical systems (CPS) new methods are required to deal with complexity. The concept of Model Based Systems Engineering (MBSE) appears to be a promising approach, even though the common paradigm of object modelling poses a challenge for stakeholders from different domains. To better enable stakeholder integration, in recent past the concept of Domain Specific Systems Engineering (DSSE) has been proposed. This concept aims at establishing a modelling approach around domain specific viewpoints and model kinds. The DSSE approach could have been validated in different domains so far. To enable the integration of systems from different domains into System-of-Systems (SoS), this paper contributes conceptual thoughts on how to extend the DSSE approach for application in System-of-Systems Engineering (SoSE). For this purpose, the paper first gives a brief summary on the core concepts of DSSE. Further, a case study is realized to learn about the needs and limitations when it comes to extending DSSE for System-of-Systems Engineering. Finally, identified research items are discussed in more detail and an outlook to our future work is presented.
