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.
