本发明公开了一种装备数字孪生组合模型可信度评估方法及系统，涉及装备评估技术领域。将系统根据各子系统之间相互影响关系进行模型结构划分，然后分析可信度评估任务，利用分析结果将单元模型按照学科领域进行划分，最后计算各子模型的演化可信度和各子系统的基础可信度，并对所述演化可信度和所述基础可信度进行单学科内的聚合和多学科间的聚合得到组合模型可信度。设计了一套针对装备数字孪生组合模型可信度评估的流程；充分考虑可实施性、科学性、合理性，提出了组合模型可信度计算所需的两项关键指标，即演化可信度和动态模型可信度。提出了一套针对装备数字孪生组合模型的多学科，多粒度，动态可信度值聚合方法。 The invention discloses an equipment digital twin combination model credibility evaluation method and system, and relates to the technical field of equipment evaluation. The method comprises the following steps: carrying out model structure division on a system according to a mutual influence relationship among subsystems, then analyzing a credibility evaluation task, dividing a unit model according to a subject field by utilizing an analysis result, and finally calculating evolution credibility of each sub-model and basic credibility of each subsystem. And carrying out aggregation in a single subject and aggregation among multiple subjects on the evolution credibility and the basic credibility to obtain the credibility of the
