Workflow model supporting the concurrency of CAD/CAPP

To manage, plan, coordinate and control the concurrent design process of computer aided design/computer aided procedure plan effectively, referring to WorkFlow Management (WFM) idea, a workflow model of the concurrent design process of computer aided design/computer aided procedure plan was established. The process model of the workflow was established by the Generalized Stochastic Petri Nets, and the abstract model was set up that was convenient for computer to deal with. This process model associated with Task/Activity model, Organization model and Data model constituted the holonomic workflow model of the concurrent design process of computer aided design/computer aided procedure plan. At last its running and controlling mode was given.
