Petri net-based modelling of workflow systems: An overview

Despite their wide range of applications, workflow systems still suffer from lack of an agreed and standard modelling technique. It is a motivating research area and some researchers have proposed different modelling techniques. Petri nets. among the other techniques, are one of the mainly used modelling techniques for both qualitative and quantitative analysis of workflow and workflow systems. We have briefly presented a way of mapping workflow into Petri nets, which can be used as a basis for such systems. A lot of available papers on Petri net-based modelling of workflow have been reviewed and classified. (C) 2001 Elsevier Science B.V. All rights reserved.
