[Abstract]:As the concept of service economy has been widely disseminated and deepened in the world, the development of manufacturing industry has changed dramatically so far. In the face of the complex competitive environment, the manufacturing industry is facing more and more challenges. The role of knowledge in the enterprise is becoming more and more obvious. Under the condition of shorter product design cycle and shorter delivery time, with the explosive growth of knowledge, the variety of knowledge types and the lack of effective knowledge sharing mechanism, the search time of knowledge is too long. Therefore, manufacturing enterprises need to build a complete set of knowledge service methods and technologies, timely and quickly respond to the rapidly changing market environment, and develop personalized products to meet the diverse needs of customers. The main contents of this thesis are as follows: (1) the general framework of knowledge management service in product design. This paper constructs the architecture of product design knowledge management service, defines the concepts and terms of knowledge management and service, and discusses the relevant stakeholders of product design knowledge management service. The overall process of implementing product design knowledge management service is established. (2) Product design knowledge representation and sharing method. The classification method of product design knowledge is defined, the definition and characteristics of all kinds of knowledge are given, the knowledge representation framework based on XTM topic map is proposed, and the development process ontology model is constructed respectively. The object ontology model and the knowledge object ontology model are developed, four kinds of knowledge ontology are constructed, and the expression structure model based on XTM is constructed. The general framework of knowledge organization and sharing and the framework of knowledge integration based on ontology are proposed. The knowledge integration ontology and the mapping adapter between knowledge integration ontology and knowledge representation ontology are defined. Then, the knowledge requirement of product design is summarized and analyzed. The knowledge requirement is divided into three dimensions and discussed separately. On this basis, knowledge retrieval technology and algorithm are constructed. (3) knowledge push method in product design process. Based on the knowledge needs of product design users, three kinds of knowledge requirements in the process of product design are established, that is, knowledge needs based on design tasks, knowledge requirements based on interest and domain experts' knowledge requirements. According to different knowledge requirements, the corresponding push strategies are formulated, and the process of knowledge push is constructed. On this basis, a task-based knowledge push method is proposed. Knowledge push method based on interest and expert knowledge push method. (4) Product design knowledge management service mechanism and evaluation method. This paper analyzes the relevant stakeholders of knowledge service, constructs the process of knowledge service on the demand side and the provider side, analyzes the characteristic attribute of the knowledge service demand and the characteristic attribute of the knowledge service resource, and constructs the mapping and matching process of knowledge service. On this basis, a knowledge service matching algorithm is designed and developed. This paper analyzes the characteristics of product design knowledge management service evaluation, and constructs the evaluation index system of product design knowledge management service platform based on the requirement characteristics of knowledge service and service resource characteristics. Aiming at the evaluation of knowledge management service, this paper constructs the evaluation method of knowledge management service, and puts forward some suggestions to improve it according to the different evaluation results. On this basis, the prototype demonstration system is developed, and the above research results are verified by application examples. The framework, methods, models and algorithms provided in this paper solve to some extent the key problems faced by enterprises in the implementation of knowledge management services in product design, and help enterprises to improve the efficiency of product design.
