Executable architecture modeling and analysis for system-of-systems

To address the challenges such as dynamic issues of system-of-systems(SoS) components and requirements,executable architecture modeling and analysis is proposed to enable overarching design that facilitate the acquisition of key information on SoS development as early as possible.Firstly,the semantic conceptual model was presented to depict the semantic relationships of constituent architecture data elements,and architecture static models were built by the architecture description of core entities and their associations.Secondly,the creation of executable models from static models with a bi-directional traceable way was also studied.Then,architecture analyses using static and executable models were discussed,including static analysis,dynamic analysis,and experimental analysis.Finally,a fictitious key area air defense SoS was used to illustrate the feasibility of the approach.
