Research on service planning of distributed heterogeneous design resources

The composition and reuse of distributed design resources is the key issue in collaborative operation of complicated products. In the first place, a collaborative service framework aiding design resources reuse is established to help encapsulate reusable resources. Meanwhile, to realize interoperability between function and data of heterogeneous resources, shared ontology and private ontology are separately built for different design disciplines and tool resources within the disciplines. Then, collaborative service planning is divided into different stages. And generating algorithm serving planning program is proposed to obtain feasible program collection of service composition. Finally, taking design of aero engine compressor as an example, the effectiveness of collaborative service planning algorithm is verified by providing an atomic service ontology instance.
