Abstract—Real time systems have a natural executing policy of urgency. However, real time process algebras of nowadays cannot specify this basic executing policy which limits their expressiveness. There is only one default policy called “maximal progress” in process algebras which is not enough to specify the behaviors of real time systems. Based on this, we propose a real time process algebra with urgency executing policy which can specify the behaviors of real time systems.

Index Terms—process algebra, executing policy, real time, urgency.
