Research Of Manufacturing Grid Resource Information Sharing Technology

Manufacturing Grid has connected and shared all kinds of manufacturing resources which dispersed all over the world, and it has composed a huge resources lib. If someone wants to use the resources of the Manufacturing Grid resource lib conveniently just like local's, it's the fundamental to effectively find the needed resources information. Since different users adopted different ways to construct modules, there are kinds of isomers. All of these block the exchange information among users. In order to avoid these limitations, we have this paper to explore the Manufacturing Grid resource information sharing methods, achieving getting info from isomers and info exchange among them, eventually make info-sharing realized. Manufacturing Grid resource information sharing technology based on the semantic description of resource info, using grid computing, Ontology technology and web service technology, encapsulating the resource info as service, matching these services base on ontology concept similarity, adopting querying and analysing algorithm to discover the related info. It is a fast, exact information sharing technology.Based on the web service architecture, combining the Ontology technology and web service technology, we constructed frame module of the manufacturing grid resources information sharing, further more, we designed the functional component and researched the work flow of information sharing.In order to adding the semantic information to description manufacturing grid resources info, we used the Ontology constructing technology which from bottom to top, designed the conceive ontology formula from structure or semi-structure, established the manufacturing resources examination ontology. So we could make the description consistent from different making-area source, realizing the semantic description to service. Through importing the classification mechanism which is provided by ontology and OWL-S to service register center, we optimized storage methods of service, resolved the semantic info's not supporting of service register center. To discover the manufacturing resources fleetly, effectively and accurately, we studied the manufacturing resources discover method. We analyzed the resource info querying and dealing engine architecture. Then, we designed the querying and analysing algorithm which is used in manufacturing resources info querying and dealing engine. Analysing the query, according to the concept similarity, the algorithm changes it to the query of different info sources.At last, under the project of 'manufacturing grid resource-sharing service platform"s support, we have developed the manufacturing grid resource information sharing demon system, and assured the feasibility of the research.
