摘　　要：复杂故障需要多诊断资源基于信息共享来进行协同诊断,但其中的一个问题是诊断协作过程复杂,表现为诊断过程中的角色和任务多种多样且动态变化。从诊断任务的角度,引入了DTBAC模型来细化协作过程,DTBAC模型以任务为动态活动的最小单位。具体介绍了该模型中的角色和任务两个元素,诊断资源是最重要的角色,而诊断任务具有授权期限。给出了一个从服务角度出发的诊断角色和诊断任务匹配算法并进行了验证。结论进行了总结并指出了进一步研究点。Complex fault needs cooperative diagnosis which involved multi-diagnosis resources based on information sharing,but one problem is that the diagnosis cooperative process is too complicated which expresses as role and task of RCFD are dynamic and various.In the foundation of diagnosis task,DTBAC（Dynamic Task-based Access Control） model was introduced to refine collaboration process,this model takes diagnosis task as minimum dynamic action unit,and the roles and tasks elements of this model was described concretely,diagno-sis resource is the most important role and diagnosis task has permission time limit.Moreover,the coupling of diagnosis roles with diagnosis tasks was primary content in above process,a coupling algorithm was presented from the point of service.The conclusion indicates further studying points.
