Virtual Manufacturing System is a computer model that represents the precise and whole structure of manufacturing systems and simulates their physical and logical behavior in operation, as well as interacting with the real manufacturing system. Its concept is specified as the model of present or future manufacturing systems with all products, processes, and control data. Before information and control data are used in the real system, their verification is performed within virtual manufacturing environment. In addition, its status and information is fed back to the virtual system from the real system.
Virtual environments will provide visualization technology for virtual manufacturing. The virtual prototype is an essential component in the virtual product life cycle, while the virtual factory caters for operations needed for fabricating products. Therefore, the developments in the area of virtual prototyping and virtual factory will enhance the capabilities of virtual manufacturing.
The major benefit of a virtual manufacturing is that physical system components (such as equipment and materials) as well as conceptual system comp vonents (e.g., process plans and equipment schedules) can be easily represented through the creation of virtual manufacturing entities that emulate their structure and function. These entities can be added to or removed from the virtual plant as necessary with minimal impact on other system data. The software entities of the virtual factory have a high correspondence with real system components, thereby lending validity to simulations carried out in the virtual system meant to aid decision-makers in the real system.
For virtual manufacturing, three major paradigms have been proposed, such as Design- centered VM, Production-centered VM, and Control- centered VM. The design-centered VM provides an environment for designers to design products and to evaluate the manufacturability and affordability of products. The results of design-centered VM include the product model, cost estimate, and so forth. Thus, potential problems with the design can be identified and its merit can be estimated. In order to maintain the manufacturing proficiency without actual building products, production-centered VM provides an environment for generating process plans and production plans, for planning resource requirements (new equipment purchase, etc.), and for evaluating these plans. This can provide more accurate cost information and schedules for product delivery. By providing the capability to simulate actual production, control-centered VM offers the environment for engineers to evaluate new or revised product designs with respect to shop floor related activities. Control-centered VM provides information for optimizing manufacturing processes and improving manufacturing systems.

虚拟生产系统是一种计算机模型,精确展现了生产系统的整个结构,模拟了其在运转过程中的物理和逻辑行为,同时也结合了现实生产系统.虚拟生产系统的概念是所有目前和将来生产系统的产品、过程以及控制数据模型.在未采用信息和控制数据之前,现实生产系统的验证是在虚拟生产环境下进行的.另外,现实生产系统会将其状态和信息反馈到虚拟系统.
虚拟环境为虚拟生产提供虚拟技术. 虚拟原型在虚拟产品生命周期中是一个主要部分,虚拟工厂需要迎合这些产品制作的操作.因此,虚拟原型与虚拟工厂领域的发展能够提高虚拟生产的能力.
虚拟生产的一个主要益处就是,通过模仿其结构和功能的虚拟生产实体的创作,虚拟系统组件(比如设备和物料)和概念系统组件(如果成计划和设备时间表) 能够被简单的表现出来.这些实体可以依据需要在虚拟工厂中添加或移除,而不对其它系统数据产生很大影响.虚拟工厂的软件实体与现实系统组件有着很大的联系,因此,在虚拟系统中执行的有效模拟对现实系统中的决策者帮助很大、
对于虚拟生产来说有三个典型范例,如以设计为中心的VM,以生产为中心的VM以及控制为中心的VM. 以设计为中心的VM为设计者提供了一个环境来设计产品并对产品的工艺性及其可购性进行评估.以设计为中心的VM的结果包括产品模型、成本预估等.因此便可以发现设计的潜在问题,其优势也可得到预测.为了在没有实体产品的情况下维持生产高效性, 以生产为中心的VM 提供一种环境,能够生成生产计划、过程计划及资源要求计划(新设备采购等),并对这些计划进行评估.这样能够提供更准确的成本信息以及产品发货时间信息.通过模拟实际生产过程, 以控制为中心的VM为工程师提供了一个环境,可以评估新产品或新修改的产品设计以及制造现场相关活动.以控制为中心的VM 为优化生产过程和改进生产系统提供有效信息.
