Business Process Analysis Method Based on Petri Nets

To better reorganize and optimize business process, Petri nets is a good formal tool. However, the prototype Petri nets can't fully describe the related properties of the business process. In this paper, the time and cost attributes are added to the Petri nets and it is called the extended generalized stochastic Petri nets. On this basis, the performance evaluation model is proposed. Execution efficiency and cost of Business process can be got by the evaluation model. They provide a direct basis for business process reengineering and optimization. Finally, the effectiveness of the model is validated through case study.
