摘　　要：为解决协同装配设计中敏感信息的保护问题,提出了面向协同装配设计的基于角色显示的技术。在该显示技术中,结合角色的访问控制与强制的访问控制,建立访问矩阵对用户进行访问控制。依据角色的访问权限与特征的安全等级,提出了基于特征的种类删减连续多分辨率模型,定义记录度量α控制不同角色得到的不同分辨率的装配模型。最后,通过建立基于角色显示的协同设计原型系统验证了该技术的有效性。To resolve sensitive information protection in collaborative assembly design, a role-based viewing technique oriented to collaborative assembly design was proposed. In this technique, to control the users＇ accesses, the Role-Based Access Control （RBAC） and the Mandatory Access Control （MAC） were integrated to construct access matrix. According to the access privilege of roles and the security level of features, the feature-based genus reduction and continuous multi-resolution model was put forward, and record metric α was defined to control assembly models with different resolutions achieved by different roles. The prototype system of Role-based Viewing in Computer Supported Collaborative Design （RVCSCD） was given to reveal the effectiveness of the role-based viewing technique.
