Research of collaborative process workflow modeling based on stochastic Petri nets

Collaborative process workflow is able to implement effective control and management for process planning flow and meet the process informationization needs of manufacturing enterprises. With the application of stochastic Petri nets (SPN) to the model of collaborative process workflow, the article proposes the method of collaborative process workflow modeling. The relationship of actual process flow and the elements of SPN is studied. This model is on flow described based on SPN, and also established by use case diagram and sequence diagram of UML to compensate for the lack of SPN. Finally, a prototype system is developed based on the model built by this article combining with the actual process situation of an enterprise.
