Modal Logic and Bisimulation for Generalized Synchronization Trees

This poster surveys results obtained by the project team in the area of logical characterizations for bisimulation over a general mathematical model for cyber-physical systems (CPSs) called Generalized Synchronization Trees (GSTs). GSTs extend traditional models for discrete-event systems with capabilities for modeling non-discrete behavior, and are intended to serve as a vehicle for giving mathematically well-defined notions of compositions for CPSs. Bisimulation represents a notion of equivalence over GSTs that captures when two GSTs are indistinguishable to an outside observer.
