Petri net based verification of a cooperative work flow model

This paper exploits the theory of Petri nets to verify reachability and soundness of a cooperative workflow model. First, we outline a cooperative workflow model, which is a modified version of Bonita workflow model. Bonita is open source cooperative workflow management software which is an ongoing project from object Web consortium. Then we describe the cooperative workflow model using a special kind of Petri net called Wf-net. Next we employ WF-net for verification of the model for reachability and soundness properties. The Petri net based verification shows that the model is reachable and sound.
