Hierarchical Modeling of Recipe Controllers - A Practical Approach
The paper presents an approach for modelling of structured control recipes, The recipes are modelled by means of hierarchical high-level Petri nets. Based on the capabilities of tools for high-level Petri nets, as for example Design/CPN, we are able to debug and simulate our models.
