Research On Knowledge Integration Of Business Process Of Manufacturing Enterprise Based On Ontology

With the arrival of knowledge economy ages, the key to improve the competence for the manufacturing enterprises is to realize knowledge integration so as to organize knowledge resource and share and reuse knowledge efficiently. With the support from the item of State 863 High-Tech R&D Program of China(No.2006AA04Z157 and No.2003AA414045) and the major research project of Zhejiang manufacturing enterprise informationization engineering (No.2005C11035), based on the theories and methods of ontology, the theory and technology of knowledge integration for the business process of the manufacturing enterprises was researched.In Chapter 1, the effect of knowledge integration for improving creativity of manufacturing enterprises and the efficiency of the business process was set forth. The status of knowledge integration of current manufacturing enterprises was analyzed and the problems were pointed out. The studies on knowledge integration were summarized, the effect of ontology to knowledge integration was analyzed, the demand for knowledge integration of the business process of manufacturing enterprises was researched. Finally the purpose, content and framework of this dissertation were proposed.In Chapter 2, the problems of business collaboration of manufacturing enterprises were pointed out, the case of manufacturing enterprise business process knowledge integration based on ontology was studied. In the framework, the model of business process ontology, the model of software component ontology, and the model of knowledge ontology were separately studied for manufacturing enterprises from the three levels- business process level, software component level and knowledge level. The architecture of knowledge integration of business process of manufacturing enterprises was built and the integration framework of multiple-level ontology for business process was proposed.In Chapter 3, the hiberarchy of ontology was analyzed, and the inner structure of ontology representation was studied. Based on the construction principle of ontology, the method of modularization ontology model construction for the total life cycle of knowledge was presented. Then the case of jewelry design knowledge was used to explain the method of modularization ontology model construction for the total life cycle of knowledge.In Chapter 4, aiming at finding the relations of mappings for heterogeneous ontologies, the process of mapping finding was researched, a method of similarity calculation based on the semantics of element names was presented. Mapping transform model based on general ontology was established to realize the mapping transform of heterogeneous ontologies, the heuristic algorithm of general ontology design was proposed. In the share pattern of general ontology, a method of ontology mapping transform based on rules was presented. The mechanism of mapping transform was studied to different mapping objects such as mapping identifiers, mapping data types, mapping constraints and mapping instances. At last a case was given to illuminate the process of mapping finding and mapping transform method.In Chapter 5, the situation of the knowledge resource organization was analyzed, then the method based on knowledge map was put forward to organize multiple ontologies knowledge of the manufacturing enterprise. The concept of knowledge map is given, the function of the knowledge map to organize the multiple ontologies knowledge was analyzed, the structure of knowledge map was described. The construct approach of knowledge map was proposed, the four kinds of relations among explicit knowledge and tacit knowledge were analyzed. The method of multiple ontology knowledge retrieval based on knowledge map was presented and the method was applied to retrieve knowledge in the jewelry design.In Chapter 6, using the theories and the technology presented in the dissertation, the platform of the knowledge integration based on ontology was developed, the principle of the integration platform was researched, and the control method was studied. The function structure of the platform was introduced.In chapter 7, the research in the dissertation and the future research directions were summarized.
