Based On Petri Net Theory Pdm Workflow Management Systems Research And Development

As business environment changes, enterprises urgently needs to combine PDM technology with workflow management technology, especially to integrate workflow management into a PDM system to improve the performance of the PDM workflow management function. And the key to implementing the workflow management system in a PDM system is workflow-modeling technology.In this paper, several methods of workflow management are analyzed. An expanded Petri net-function Petri net and the workflow management model based on it are presented. And the correctness analyses, performance appraisement and optimization methods of such a model are discussed. The flow classes, activity classes and relation classes of such a model are also built through the OOA technology.And then, based on the analysis for the information intercommunion between workflow management system and PDM system, the system implementation technology is discussed. And the integration framework and the system architecture are brought forward, and applied to the 650PDM system. In this system, a workflow management system is successfully integrated.
