Abstract

This paper presents two related algebras which can be used to specify and analyse concurrent systems with explicit timing information. The first algebra is based on process expressions, called t-expressions, and a system of SOS rules providing their operational semantics. The second algebra is based on a class of time Petri nets, called ct-boxes, and their transition firing rule. The two algebras are related through a mapping which, for a t-expression, returns a corresponding ct-box with behaviourally equivalent transition system. The resulting model, called the Time Petri Box Calculus (tPBC), extends the existing approach of the Petri Box Calculus (PBC).
