Cyber-physical systems (CPSs) are characterized by many new modalities and domains. They use many different modeling paradigms, methods, and solutions, which leads to challenges known to the Modeling and Simulation (M&S) community from hybrid simulation approaches. Recent contributions often use hybrid simulation to address solutions using more than one modeling paradigm, combining agents, discrete event, and system dynamics. However, that is limited with respect to covering all the modalities in such complex systems, for example, domains like cognitive modeling are outside these identified solution approaches. Likewise, cybersecurity, is across the landscape and integrating cyber aspects is not straightforward. Co-simulation has emerged as a viable option to bring two or more simulators together. This requires explicit simulation engineering as integrating multiple simulators has its own challenges. Architecting a simulation solution requires an understanding of multiple domains, coordination among multidisciplinary Subject Matter Experts (SMEs) and aligning abstractions/assumptions inherent in the simulators, to the extent that the resulting model is a useful model, a validated model. This talk will present the state-of-the-art in CPS M&S and various research opportunities that are arising out of the existing gaps with respect to multi-(modalities, domains, paradigms, etc.).
