The development of aeroengine needs the collaboration of many enterprises. In order to realize the share and optimization configuration of different enterprises' design and manufacturing resources, a method of realizing product collaborative development based on grid service is proposed. In the method, the collaboration among enterprises is realized by grid service cell. The grid service cell is an encapsulated service agent which can provide certain design and manufacturing abilities through the network. Enterprises can release their grid service information in the portal and create their grid service cells, and then they become the grid service supplier. The customers use the grid service matching engine to search the suited grid services in the portal and use these services to accomplish the product development. Accordingly the method can realize the optimization configuration of different enterprises' design and manufacturing resources. Therefore, a prototype system of networked collaborative development of aeroengine based on grid service is developed. In the system, an ontology of aeroengine networked collaborative development is proposed, and the models of grid service cell and grid service requirement are built. Aiming at the matching of the grid service, a matching method based on semantic is proposed; a mathematic model for grid service matching is created and the corresponding matching algorithm is presented. Finally, we validated the prototype system with the example of the collaborative development of an aeroengine part.
