Abstract

Structures called concatenable weighted pomsets are introduced which can serve as models of processes of Petri nets, including nets with time features. Operations on such structures are defined which allow to combine them sequentially and in parallel. These operations correspond to natural operations on processes. They make the universe of concatenable weighted pomsets a partial algebra which appears to be a symmetric strict monoidal category. Sets of processes of timed and time Petri nets are characterized as subsets of this algebra.
