【摘要】 产品信息模型的建立是企业应用产品数据管理(PDM)系统的关键。提出一种PDM系统中全局产品信息模型构建方法——面向企业的全局产品结构模型(EOGPSM)。根据产品开发的特点和要求,提出从资源模型、功能模型、原理模型、结构模型、制造模型等5个方面对EOGPSM的信息需求框架进行描述。在此基础上,给出EOGPSM相应的信息集成框架,并对其信息集成原理与相关算法进行了研究。结果表明,该模型的构建方法可用于企业PDM系统。更多还原

【Abstract】 Product information modeling is highly valued as the key field in product data management (PDM) systems. A method was developed to construct the global product information model in PDM systems, the enterprise-oriented global product structure model (EOGPSM). The internal traits and the universal demands of the product development process were used to design the information demand frame of the EOGPSM with resource models, function models, principle models, structure models and manufacturing models. An information integration frame was developed using information integration theory. The result shows that the EOGPSM method can be applied to enterprise PDM systems.更多还原
