Workshop on Programming Theory

Actor models have been used for modeling and analyzing distributed and asynchronous systems. Moreover, actors are being increasingly used in industry, and new actor-based languages are designed and used by Google and Microsoft, for example Go, P and Orleans. In the new era of cyber-physical systems, we need methods and techniques for safety and performance assurance of timed models. Floating Time Transition System (FTTS) is introduced as an event-based semantics for the actor-based language Timed Rebeca, and it is used for efficient model checking and performance evaluation of timed actors. I will explain FTTS and the action-based weak bisimulation relation between FTTS and the standard semantics in Timed Transition System, and how this relation guarantees preserving of the event-based properties. I will also show how Timed Rebeca is used in safety assurance and performance evaluation of different systems, like Network on Chip architectures, sensor network applications, Traffic Control systems, and quadcopter.
