New extended workflow net for formalizing workflow patterns

  • Received Date: 06 Jan 2006

  • To satisfy the enterprise process modeling requirements in the ability of powerf ul expression and analysis, a new extended workflow net(EWF_net) was proposed fo r formalizing workflow patterns. EWF_net extended workflow net(WF_net) by adding some mechanisms, and improved the power of describing dynamic workflow mode l of WF_net. EWF_net was designed for directly describing various comp lex process, especially multiple instances, cancel activity, advanced parallel a nd synchronization which were not supported by most Petri-net models. Control v ariable was introduced in EWF_net for describing the relevant data of workflow m odel. In EWF_net, a special transition,transfer transition was introduced for s upporting dynamic routing of the model. A formal correctness analysis method of EWF_net was given based on the analysis techniques of Petri-net. The correctness analy s is of EWF_net consisted of the analysis of consistent and the analysis of soundne ss of corresponding WF_net. Finally, an application example was described and an alyzed in EWF_net which showed its power of description and analysis.
