Exposing and Controlling Emergent Behaviors in a System of Systems (SoS) Model

Presenter: Dr. Kristin Giammarco

Abstract: This presentation shows how to segment and extend a SysML activity model for emergent behavior analysis using Monterey Phoenix (MP). MP generates sets of behavior scenarios that are exhaustive up to a user-defined scope (number of iterations). After summarizing relevant definitions, we present, discuss and analyze examples of emergent behaviors found in the extended model, some of which contradict stakeholder intent and inspire consideration of SoS-wide consequences if they were to occur in reality. We also show how emergent behaviors may be classified as weak, strong, positive or negative. We conclude with some key takeaways and lessons learned for repeating these types of discoveries in other SoS models.

Bio: Dr. Kristin Giammarco is an Associate Professor in the Department of Systems Engineering at the Naval Postgraduate School (NPS), where she teaches courses in system architecture and design, system integration, systems software engineering, and model-based systems engineering. She conducts research in the use and development of formal methods for systems architecture modeling as well as system and software behavioral modeling and architectural patterns with students and colleagues within and outside of NPS.  Dr. Giammarco is a member of INCOSE, the Lifecycle Modeling Language Steering Committee, and the International Society for Systems Pathology.  She holds a Ph.D. in Software Engineering, an M.S. in Systems Engineering Management, and a Certificate in Advanced Systems Engineering from NPS and a B.E. in Electrical Engineering from Stevens Institute of Technology.
