Pattern based workflow design using reference nets

Abstract

The development of workflow applications requires satisfactory concepts and tools. Workflow patterns cover the conceptual part. To base the patterns on high-level Petri nets allows for the tight integration of the modelling editor with the actual execution engine. The development process of workflow applications gains from this. We propose to use Reference nets as the modelling technique, Renew as the basic execution engine, and our workflow modelling tool for the design of workflows. The latter is a plug-in for the Renew editor, which is based on the use of workflow patterns. The development process is based on prototyping. © Springer-Verlag Berlin Heidelberg 2003.
