A Petri net-based View on the Business Process Life-Cycle.

During the last 30 years Petri nets have shown a continuous popularity and durability as process modelling language. While some process modelling languages were crossed with others or even disappeared, Petri nets are continuously used as modelling language addressing various purposes in the context of business processes. In this paper, we refer to the success of Petri nets and describe business process modelling extensions as well as approaches for process modelling, simulation, execution and evaluation relying on Petri nets. The variety of Petri net-based extensions shows that Petri nets can be adapted to changing requirements for which these extensions, modifications or variants have been proposed.
