【摘要】 总结了PDM权限管理特点,重点讨论了PDM中权限的集合定义和用户权限判定的函数表示,在分析产品数据分类、企业用户组织模式和权限分类的基础上,提出了基于产品数据分类的权限管理模型,并给出了该模型的应用实例。该模型较好地协调了产品数据共享和保护两方面的需求,并且权限控制逻辑条理清楚,易于实现。更多还原

【Abstract】 In the paper,the characteristics of PDM authority management are summarized;set definitions of the authority and function expressions of decision upon user authority in PDM are discussed specially.Based on the analysis of product data classification,user organization patterns of an enterprise and authority classification,a model of authority management based on product data classification is presented.Also,an engineering application example of the model is given at the end of the article.The model is satisfied with the requirements of both product data share and product data protection,and it has simple control logic of the authority managements and easy implementation in engineering.更多还原
