摘　　要：随着数字孪生技术应用领域的扩展,为满足数字孪生体可信度要求和推动数字孪生体可信度评估工作,对数字孪生体可信度评估过程和指标进行了研究。分析了数字孪生体的开发过程,给出了基于IDEF0(integrated computer aided manufacturing-definition method)的柔性多层级数字孪生体可信度评估过程模型构建方法。提出了过程—阶段—活动层(P-S-A)和活动—元素—特性层(A-E-F)两类指标体系,分别辅助解决缺陷回溯问题和复杂对象评估问题,并给出了指标体系范例。With the application field expansion of digital twin technology, in order to meet the requirement of digital twin credibility and promote the digital twin credibility assessment, the credibility assessment process and indicators of digital twin are researched. The development process of digital twin is analyzed and the construction method of flexible multi-layer digital twin credibility assessment process model based on IDEF0 is proposed. Two index systems, process-stage-activity layers(P-S-A) and activityelement-feature layers(A-E-F), are proposed to solve the problems of defect backtracking and evaluation of complex objects. Several examples of index system are given.
