【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。更多还原

【Abstract】 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.更多还原
