Abstract: To achieve the intelligence of manufacturing system's service process in collaborative manufacturing environment, a paradigm of manufacturing on demand based on Demand-Resources-Service-Process (DRSP) was proposed. Combined with the technologies of ontology, semantic reasoning, a reasoning framework of service process on demand based on Semantic Web Rule Language (SWRL) was for mulated. The ontology concept and relation model of manufacturing needs, resources, services and processes were constructed, and ontology knowledge base of reasoning framework was set up. Dynamic service process thought was generated based on the composition of service on demand. The semantic Web service function semantics and the dynamic service interactive feature of of before and after were described by Input-Output-Precondition-Effect (IOPE) model, and the Description Logic (DL) rules of service process trigger reasoning were extracted. Through the mapping from DL rule to ontology knowledge, SWRL rules were constructed. The application model of reasoning was achieved by Protégé and Jess reasoning engine, and validity of the method was demonstrated through the reasoning experiment.
