Cloud manufacturing is a new service-oriented networked manufacturing model in which manufacturing resources can be shared in the cloud for customers to utilize as needed. Traditional resource servitization methods are mostly based on SPOA (Service Protocol-Oriented Architecture), which lacks the flexibility to cope with the dynamic nature of the network and the manufacturing resources. In this paper, based on the characteristics of manufacturing resources and the network, the SOOA (Service Object-Oriented Architecture) is adopted as the underling service architecture for resource servitization, and an SOOA-based resource servitization method is proposed, in which three stages are involved – service interface definition, manufacturing resource encapsulation and dynamic provisioning of manufacturing services. Through the three stages, different kinds of manufacturing resources from different perspectives, including software and hardware resources, static and dynamic resources, or unique and replaceable resources, can all be provisioned and accessed as manufacturing services on the dynamic network with standardized interfaces and SOOA characteristics. This approach can provide support for connect-in of manufacturing resources from resource providers and can adapt to the dynamic nature of manufacturing resources and the network very well.
