为了完整地描述云制造资源的属性,实现云制造资源物理-虚拟资源的映射与转化,结合云制造服务体系框架、云制造资源的特点及分类,指出了云制造资源虚拟化的原则——系统性、针对性、适应性、扩展性、接口统一和动态性;然后以制造设备资源为例,描述特征模型,并通过扩展开源软件CloudSim Java类给出了制造设备资源虚拟化模板;最后以零件加工为例,利用Tuscany SCA对已虚拟化的制造设备资源进一步服务化形成云服务,并将云服务发布到服务注册中心,供云制造资源使用者查找和调用.

In order to fully describe the properties of cloud manufacturing resources and implement the mapping and transformation of physical resources to virtual ones,the service architecture of cloud manufacturing as well as the characteristics and categories of manufacturing resources is taken into consideration,and the virtualization principles of cloud manufacturing resources,such as the systematicness,the pertinence,the adaptability,the expansibility,the interface uniformity and the dynamism,are pointed out.Then,manufacturing equipment resources are exemplified to characterize the model,and a template for resource virtualization is presented by extending the Java class in open source software CloudSim.Finally,by taking a part machining service as an example,the virtualized manufacturing resources are unified as cloud services by using the open source software Tuscany SCA,and the cloud services are registered in the service registry center for the discovery and invoking of cloud manufacturing resources by users.
