The virtual manufacturing approach in this paper is close to Control-centered YM.Fig.1 illustrates the viewpoint of the functional model of the virtual flexible manufacturing cell.Since the activity Execute real manufacturing systems depicts a model of real factory,it possibly replaces real factory.All manufacturing processes except physical elements of virtual manufacturing,such as design,process planning,scheduling,are included in the activity Operation of Virtual factory.The activity Execute simulation for virtual factory is a separate simulation model of VM system.With this virtual factory,parameters (e.g.utilization,operation time,etc.,) associated with operating a flexible manufacturing cell are simulated.And these results can provide the possibility of controlling manufacturing processes and predicting potential problems in the real manufacturing.
