Model-Based Interoperability Engineering in Systems-of-Systems and Civil Aviation

Abstract

Interoperability is the capability of multiple parties and systems to collaborate and exchange information and matter to obtain their objectives. Interoperability challenges call for a model-based systems engineering approach. This paper describes a conceptual modeling framework for model-based interoperability engineering (MoBIE) for systems of systems, which integrates multilayered interoperability specification, modeling, architecting, design, and testing. Treating interoperability infrastructure as a system in its own right, MoBIE facilitates interoperability among agents, processes, systems, services, and interfaces. MoBIE is founded on ISO 19450 standard—object-process methodology, a holistic paradigm for modeling and architecting complex, dynamic, and multidisciplinary systems—and allows for synergistic integration of the interoperability model with system-centric models. We also discuss the implementation of MoBIE with the unified modeling language. We discuss the importance of interoperability in the civil aviation domain, and apply MoBIE to analyze the passenger departure process in an airport terminal as a case-in-point. The resulting model enables architectural and operational decision making and analysis at the system-of-systems level and adds significant value at the interoperability engineering program level.
