Research On The Key Technologies Of Enterprise-Oriented Product Structure And Configuration Management

Because of the internationalization of the competition and cooperation, enterprises have to expand their markets and form their compact cooperation with using the advantage of resource and sharing the information. Served as a technology to manage the relative information and process during the making of the product of manufacturing enterprises, PDM can help enterprises to share their product data timely and support the concurrent development of the product strongly. To raise the ability of the product structure and configuration management becomes one of the hotspots for current study on the PDM. Against the present status of research and problems of the product structure and configuration management, the author has conducted relevant researches as follows:After analyzing the architecture of current PDM and the problems in its application popularization, the author advances a new thinking of PDM, which is EOPSCM (Enterprise-Oriented Product Structure and Configuration Management), and presents the construction method of EOGPSM (Enterprise-Oriented Global Product Structure Model), which support the realization of EOPSCM. Based on these, the requirements framework, the integration framework, the integration principle and the realization arithmetic of EOGPSM's information are presented, which can make the enterprises adopt the unified product information model and share the product information on each stage of product life cycle. By using the theory and algorithm of rough set, the author advances the data mining model satisfied by customer requirements, the rule extraction model of individuation configurator and the decision support model of design scheme estimation, which supports the establishment of EOGPSM.By applying the object-oriented method to analyze EOGPSM, the author advances a product structure model based on assembly topological tree and component topological tree, and then researches on product prototype structure model class. Homologous resource coding system and a relevant algorithm of product structure definition are advanced, which can help people study the product structure management in EOPSCM. The author also utilizes such constraint rule libraries as view constraint, version constraint, variable optional constraint and validity constraint to realize fundamental functions of product configuration management, thereby accomplishes the homologous representation of product configuration management and analyzes the work process of product configuration management. Finally, the study of EOPSCM based on CORBA is put forward from product structure definition model and product configuration management model.
