Key Technologies Research Of Part Process Information System Of Virtual Enterprise-oriented

With the more competitive market and the more rapid process of economy globalization, virtual enterprises slowly show their great advantages due to the features. However, information sharing and integration of different place and heterogeneous becomes one of the problems that need to rapidly be solved and the basic communication framework of all kinds of information.which includes process information acquirement, transmission and management. They are the basis of virtual enterprise, and the main facts different from the conventional enterprise. The methods of key problem directly decide the success or failure of the implementation of virtual enterprises not only commercial enterprises but also military enterprises. Therefore, it is theory meaning and practical value for the research of information acquirement, transmission and management of virtual enterprise- oriented.Present conditions of domestic and foreign research of part information acquirement, transmission and management in the virtual enterprise are analyzed. According to the information features of virtual enterprise, the concrete contexts of part process information virtual enterprise-oriented are difined, and functional requirement of part process information system are analyzed. The structure of part process information system is proposed on these bases. The crucial and difficult problems of information communication are farther analyzed, which is the basis for the research in depth of information acquirement, transmission and management.On the basis of analysis and research of present condition of domestic and foreign of part information model, the different methods of erecting model are compared. The concept model of part process information is erected by the method of features-based. The cooperation and communication model among the features of part process information is erected by combining with multi-agent technology, and the related mathematic express is given. These are the basic work for erecting the process information database of part.The method of acquiring part process information in different place and heterogeneous is proposed by using the combination algorithm and fuzzy theory. Part process information recognition module is developed, which can recognize the features of part and features form, geometry attribute. The information database of part process is erected for satisfying the information requirement of different sub-enterprises.The information transmission of part process in the pattern of virtual enterprise is settled. The method is that the information in the table of information database being...
