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...
The research presented the supply chain operation model based on networked manufacturing. It employs the Object-oriented Petri Net(OPN) to analyze the process of supply chain. The model of each object who takes part in supply chain operation was designed and the synthetical model was presented. Then, some properties such as deadlock, overflow and conflict can be analyzed. In such supply chain operation,...
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...
