Construction Of Knowledge Library For Assembly Simulation Resources

With the development of the aviation industrial informationization formed large amounts of original data which is need to be processed and applied. According to the theoretical and practical results of the current domestic and international knowledge management and knowledge engineering on knowledge representation, classification, use and other aspects, this paper makes a research on the theory and methods to build assembly simulation resources knowledge library, discourses its framework, content and function. The main research of this paper are as follows:First of all, it is the analysis of the urgent needs of knowledge for the development of aviation industry and the present situation in China and abroad, then the paper introduces the main contents, technological routine and innovative points.Second, the paper makes a research on the classification and management of assembly simulation resources, and codes and manages the assembly process resources according to national standards, and discusses methods and steps for creating a model library by CATIA , and builds a model library of physical resources.Then, the paper makes a research on the design of resources information model and functional model of the knowledge library system for assembly simulation resources. With the properties and characteristics of assembly simulation resources,the paper makes a research on inferring based on production rule and control strategy, then designed a star database model. At last, the paper makes a research on the overall framework and inner structure of the assembly simulation resource knowledge library system, and according to the application of knowledge library system projects, makes a research on how to design an effective inference engine to create an ideal knowledge library system.Knowledge library is the core enterprise resource management in the information age. This paper aims at the knowledge library for aircraft assembly simulation resources, and some key technologies are solved, for example, the creation of model library, system model and knowledge inference. With this knowledge library system managers can know in time the assembly process status, all kinds of assembly resource status, and the plan implemented status and so on, and can also track assembly resource information in real time, and can control the assembly process status from the overall perspective, thus the management efficiency of assembly resource is improved. It has great theoretical significance and application value to the aircraft assembly and manufacture industry.
