Knowledge service modeling approach for group enterprise cloud manufacturing

To resolve problems of knowledge resources sharing and utilization in Cloud Manufacturing(CMfg), the application pattern of knowledge service for group enterprise CMfg were introduced based on requirements analysis of knowledge service. Users could easily get knowledge service from CMfg service platform and provide the knowledge service within or outside the group enterprise. The knowledge service system architecture was constructed in CMfg environment. Knowledge service methods and modeling methods of static and dynamic were put forward. Static knowledge service model was established through multi-domain ontology, distributed index and knowledge service demand. Dynamic knowledge service model was established by analyzing the business processes knowledge, and encapsulating the methods and software tools as services. The service processes of two kinds of knowledge services were demonstrated by an application example.
