Petri Net Technology (PNT)

sponsored by the Deutsche Forschungsgemeinschaft (DFG)

Results of the First Phase

The DFG-Forschergruppe Petri Net Technology has been established by the German Research Council in April 1996 and is a common research project between H. Weber (Coordinator), H. Ehrig (both from the Technical University Berlin) and W. Reisig (Humboldt University Berlin), supported by the Deutsche Forschungsgemeinschaft (DFG).

The main objective of the research group Petri Net Technology is to:

The first major steps towards this goal has been the conception and initial realization of the >>Petri Net Baukasten<<. Conceptually, the >>Petri Net Baukasten<< is divided into three different views: the Application Developer View, the Tool Developer View, nd the Expert View. These views are related via the Common Base, a classification of Petri net techniques. This classification is presented semi-formally by class diagrams in the Unified Modeling Language. The subject of the classification are Petri net types. The Application Developer View supports the access of an application developer to the Petri net techniques described in the Common Base. The Tool Developer View and the Expert View serve the corresponding users of the >>Petri Net Baukasten<<.

The conception of the >>Petri Net Baukasten<< is grounded on the main research areas and results of the three subgroups of the research group Petri Net Technology.

The three subgroups of the project are:

Net based software development (NSE):
Prof. Dr. H. Weber, TU Berlin

Universal approach to net based system description (UBS):
Prof. Dr. H. Ehrig, TU Berlin

Theory based Petri net applications (TheoPAn):
Prof. Dr. W. Reisig, HU Berlin
