Study of Workflow Modeling Based on Petri Net

The workflow plays an important role in improving the enterprise production efficiency of management, the information automation and the competitiveness. Simultaneously the workflow as an efficient integrated method can be applied in many kinds of domain. The related concepts of Petri nets and workflow modeling standards are introduced in the paper, including four kinds of basic structure: sequence, parallel, choice and loop. Furthermore we model a complex enterprise production and management of business processes from the real situation. The workflow model technology of Petri nets is applied in the process of produce network model and its sub-model.
