Abstract

Fehling's hierarchical Petri nets are a net modelling framework based on refinement and abstraction of nets. Object Petri nets are a Petri net-based method of encapsulation. We bring these two domains together in the new concept of hierarchical object Petri nets. Defining hierarchical object Petri nets forces us to consider what it means to preserve synchronisation when abstracting or refining an object Petri net. The goal is to provide a sound theoretical basis for building computer tools to develop high-level Petri net models following the nets-within-nets paradigm.
