Research on manufacturing resource organization model based on ontology

On the basis of analysis characteristics of some aerospace manufacturing enterprises, first, a new manufacturing resources organization model based virtual manufacturing cell (VMC) is introduced. Second, based on the ontology technology, manufacturing resource domain ontology is constructed. Then, the establish process and the formal definition of the domain ontology are given. Third, in order to solve the heterogeneous ontology integration problem, four similarity relationships and merger rules between manufacturing resources conceptions are proposed. To end this paper, an instance of manufacturing resource domain ontology is shown.
