A Modeling Method for Model-based Analysis and Design of a System-of-Systems

In recent years, a domain of Systems-of-Systems (SoS) has emerged due to the needs of utilizing collective and collaborative system capabilities. As interest in SoS engineering has grown, this study focuses on the model-based analysis and design of an SoS, and we propose a general-purpose modeling method for the model-based SoS engineering (MBSoSE). Based on requirements that modeling methods of MBSoSE approaches should fulfill, required model types are identified (19 model types) and they are classified on their different modeling purposes and concerns (6 model categories). Model types are meta-modeled using the ADOxx Metamodeling Platform and they are implemented as modeling languages in a tool, called SIMVA-SoS Modeler. Using the modeling tool developed, we designed two different SoS cases and their scenarios that can be utilized as inputs of simulation and verification tools. Through the case studies, overall applicability of our modeling method for MBSoSE is evaluated and specific modeling results are provided as base reference models.
