Abstract: To solve the problems of manufacturing resources'flexible allocation and manufacturing ability's reasonable matching under Clouds Manufacturing(CMfg)environment, Virtual Manufacturing Unit in CMfg(VMU-CM)and Virtual Manufacturing Center in CMfg(VMC-CM)were put forward, and manufacturing process of products was given based on VMC-CM. The characteristics of manufacturing resources and manufacturing ability in CMfg were analyzed. Through classification on manufacturing resources and manufacturing ability, the structure and constructing processes of VMU-CM were given. According to information of manufacturing task, a new VMU-CM for manufacturing activities was constructed. Through production process, organization structure and external service information, various VMU-CMs were integrated to construct VMC-CM. Manufacturing ability of VMC-CM was encapsulated as manufacturing service, and the manufacturing resources virtualization process of “manufacturing resources-manufacturing abilities-manufacturing services” was achieved. Part of theories of VMU-CM and VMC-CM were applied in manufacturing ability standards and manufacturing service center of group-oriented cloud manufacturing platform, and the feasibility was verified.
