| 摘 要： | 通过对产品数据管理系统的分析，本文探讨了产品数据管理系统中数据、工作流程、活动、操作和角色之间的关系，提出了基于数据、工作流程、活动、操作和角色的用户权限管理的建模方法。通过在某航空企业PDM系统中建立用户权限管理模型的应用，证明了这种方法具有简单、规范、有效等特点，井可广泛应用于其它类型的复杂信息系统中。

| Abstract: | User access control is an essential function in production data management (PDM) systems. It deals with the security, integrity and consistence of the product data in the life cycle of product. It is difficult for user access control modeling to successfully implement PDM systems. This paper proposes a relation between data, workflow, activities, operations and roles in PDM. A method for the user access control modeling is presented based on the relation. As an example, the PDM system is applied to aircraft enterprises. The application processes of the method show that the method is easy, normal and efficient for PDM, and it has be applied to other complicated management information systems. |
