A Compositional Semantics for Timed Petri Nets1

Abstract

Timed Petri nets and their behaviours are considered. A concept of a seminet is introduced. which generalizes the concept of a net, and suitable operations on seminets are defined, which allow constructing seminets from atoms corresponding to places and transitions. The behaviours of seminets are given in the form of so called configuration systems, a notion close to labelled event structures. Such behaviours can be combined with the aid of operations corresponding to those on seminets. In particular, the behaviour of a compound seminet can be obtained by combining the behaviours of components.
