Model-Based Systems Engineering Colloquium
Model Integration Challenge in the Design of Cyber Physical Systems

Recent attention to Cyber Physical Systems (CPS) is driven by the need for deeper integration of design disciplines that dominate physical and computational domains. Consequently, heterogeneity is the norm as well as the main challenge in CPS design: components and systems are modeled using multiple physical, logical, functional and non-functional modeling aspects. The scope of relevant design domains includes (1) physical domains, such as structure, mechanical dynamics, thermal, propulsion, fluid, electrical, acoustics/vibration and (2) computational/networking domains, such as system control, sensors, health management, mission management, communication. However, the practice of multi-modeling using established domain-specific modeling languages and tools independently in the design process is insufficient. Modeling and analyzing cross-domain interactions among physical and computational/networking domains and understanding the effects of heterogeneous abstraction layers in the design flow are fundamental part of CPS design theories. The talk will cast this challenge as a model integration problem and discuss solutions for capturing interdependencies across the modeling domains using constructs for meta-model composition and integration.
Dr. Janos Sztipanovits is currently the E. Bronson Ingram Distinguished Professor of Engineering at Vanderbilt University. He is founding director of the Institute for Software Integrated Systems (ISIS). His current research interest includes the foundation and applications of Model-Integrated Computing for the design of Cyber Physical Systems. His other research contributions include structurally adaptive systems, autonomous systems, design space exploration and systems-security co-design technology. He served as program manager and acting deputy director of DARPA/ITO between 1999 and 2002. He was founding chair of the ACM Special Interest Group on Embedded Software (SIGBED). Dr. Sztipanovits was elected Fellow of the IEEE in 2000 and external member of the Hungarian Academy of Sciences in 2010. He graduated (Summa Cum Laude) from the Technical University of Budapest in 1970 and received his doctorate from the Hungarian Academy of Sciences in 1980.
