摘　　要：针对当前故障模式与影响分析(FMEA)工作存在的主观性强、改进措施操作性差、风险排序准确度不够等共性问题,提出了一种基于粗糙集理论的过程故障模式与影响分析(PFMEA)方法。应用该方法进行了太阳翼装配过程的故障模式与影响分析,并由多位专家对不同故障模式的严酷度、发生度、检测度进行共同评分,从而计算出太阳翼装配过程故障模式的粗糙域矩阵。通过质量损失函数对太阳翼装配的风险项目进行排序,风险排序结果与工程实际相吻合,最终制定出了太阳翼装配故障预防的工艺措施与关键工序控制表。太阳翼装配PFMEA的实施对其他航天产品装配生产也具有借鉴意义。Aiming at the common problems of current FMEA work such as strong subjectivity,poor operability of improvement measures,and insufficient risk ranking accuracy,this paper proposes a PFMEA method based on rough set theory.This method is used to analyze the failure mode and impact of the solar wing assembly process,and multiple experts are used to jointly score the severity,occurrence and detection degree of different failure modes,so as to calculate the rough domain matrix of the failure mode of the solar wing assembly process.According to the quality loss function,the risk items of solar wing assembly are sorted.The result of risk sorting is consistent with the actual project.Finally,the process measures and key process control tables for solar wing assembly failure prevention are formulated.The implementation of the solar wing assembly PFMEA has a reference significance for the assembly and production of other aerospace products.
