摘　　要：针对目前缺乏科学有效可诊断性评价指标体系的问题,从故障诊断性能、响应时间、测试资源3个角度构建3维可诊断性评价模型。选择10个代表性指标作为评价模型的组成元素,保证可诊断性评价模型的完备性;提出基于组合权重和灰色关联分析(grey relation analysis,GRA)的可诊断性综合评价方法,利用层次分析法(analytic hierarchy process,AHP)和熵值法计算评价指标的主观权重和客观权重,利用数学规划方法将主观权重和客观权重进行融合并利用GRA对系统的可诊断性水平进行评价。结果表明,该方法能保证可诊断性评价结果的合理性和科学性。In view of the lack of scientific and effective diagnosability evaluation index system,a three-dimensional diagnosability evaluation model is constructed from three aspects of fault diagnosis performance,response time and test resources.Ten representative indexes are selected as the elements of the evaluation model to ensure the completeness of the diagnosability evaluation model;A comprehensive evaluation method of diagnosability based on combination weight and grey relation analysis(GRA)is proposed,in which analytic hierarchy process(AHP)and entropy method are used to calculate the subjective weight and objective weight of evaluation indexes.The mathematical programming method is used to integrate the subjective weight and objective weight,and the GRA is used to evaluate the diagnosability of the system.The results show that the method ensures the rationality and scientificity of the diagnosability evaluation results.
