| Abstract: | In the process of workflow engine scheduling,the state information of the the activity instance and process instance is analyzed in this paper,and an algorithm which maps the workflow model to Petri nets based on the Petri Net modeling theory is introduced.The workflow executive engine is realized with the relational database and . NET,the process E-R and the associated data models are introduced,and the core scheduling algorithm of the workflow engine is described. Application practices show that the desig... |
