“…Compared with the ontology-based method for the breakdown of SoS missions [18], which uses the UAF at the model level before reasoning based on ontology, this study develops ontology at the metamodel level, thus providing more flexibility for the SoS modeling based on AFs. Ontologies can help to avoid ambiguities, facilitate information exchange between modules and external software, and provide a shared understanding of the design process [59]. In contrast to an ontology-based common conceptual reference used as a foundation for aircraft design processes [59], we employ the UAF metamodel to develop an ontology with greater detail on the SoS architecture.…”

System-of-systems (SoS) architecture is crucial in managing complex and interconnected systems. However, the description and modeling of SoS architecture pose significant challenges and require a structured and organized approach. In this study, a metamodel for SoS architecture that considers both structural and behavioral perspectives is defined. The metamodel is then mapped to ontologies that are enhanced with a flow-based extension to characterize architecture views. On this basis, an SoS capability ontology (SoSCO) and an SoS operational ontology (SoSOO) are built with factors, relationships, and flows. A four-step architecture process for developing capabilities and a five-step architecture process for operational modeling are provided based on the ontologies. The proposed approach is applied in a search and rescue case study, demonstrating its ability to improve operability in the early design stage. The process is implemented using the Unified Architecture Framework (UAF) so that various stakeholders and engineers can better understand and develop an SoS.
