Flow Management of Process Planning Based on Workflow

In order to implement flow management of process planning and meet the process informatization needs in manufacturing enterprises, application of workflow technology in process planning was discussed in this paper. The theory and modeling method of process planning based on workflow was studied, and the time model based on fuzzy timed Petri nets was set up, which analyzed time information of tasks in the workflow. The data model was established according to data information in the workflow, which reflected data composition and logic structure in the flow of process planning workflow execution. The mechanism of run control based on state transfer in the flow of process planning was studied. A workflow system of process planning was developed, which greatly improved the flow management capability and the efficiency of process planning.
