| 摘 要： | 指出产品数据管理(PDM)系统的权限管理不仅要面向用户,而且要面向流程和面向数据对象(即实体)。分析了PDM系统中权限管理的基本要求和权限的动态特性,把PDM系统的权限归纳为状态-实体性权限、实体性权限、功能性权限。综合运用这3种权限,可以进行多层次的动态的管理。建立了相应的PDM权限管理模型,提出了相应的数据结构与算法。

| Abstract: | The paper points out that privilege management in product data management(PDM) system should be not only user-oriented but also workflow-oriented and object-oriented.The basic problems of privilege management in PDM system and the dynamic characteristics of the privileges are analyzed.The privileges in PDM system are summarized to state-object privilege,object privilege and functional privilege.Using these three privileges the dynamic management of different levels can be achieved.The PDM privilege management model is set up and the date structure and the algorithm are given. |
