英语翻译
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.

本文中的虚拟制造方法接近于虚拟制造中的控制中心.图1（译文略）说明了在虚拟柔性制造单元的功能模型的观点.由于活动执行制造系统描绘了一个真实的真正的工厂模式,它可能会取代真正的工厂.在所有的制造过程中,除了物质要素的虚拟制造,如设计,工艺规划,调度,是在虚拟工厂经营活动范围内.虚拟工厂活动的模拟执行是一种独立的虚拟制造系统的仿真模型.有了这个虚拟工厂,与柔性制造单元操作相关的参数（如使用,操作时间等）得益模拟.而这些结果可以为生产过程的控制和预测潜在的实际生产问题的可能性做出准备.
