The invention belongs to the technical field of aircraft system tests, and particularly relates to a comprehensive evaluation method for testability indexes. The method comprises the following steps: S1, collecting testability index evaluation results of a plurality of specified types of tests; s2, determining whether each testability index reaches the standard or not according to the fault detection rate threshold value and the fault isolation rate threshold value of each testability index; s3, if all the testability indexes reach the standard, a given comprehensive evaluation conclusion is standard, and if the testability index evaluation result of a set type test is not collected, testability index self-evaluation based on external field data is carried out; s4, according to the testability index self-evaluation, obtaining a testability identification test index evaluation result; and S5, if the evaluation result of the testability identification test index reaches the standard, the given comprehensive evaluation conclusion is standard. The testability index comprehensive evaluation method provided by the invention can provide support for testability index evaluation and provide a basis for testability design improvement.
本申请属于飞机系统试验技术领域,特别涉及一种测试性指标综合评估方法。该方法包括步骤S1、收集指定的多个类型试验的测试性指标评估结果;步骤S2、根据各测试性指标的故障检测率阈值与故障隔离率阈值确定各测试性指标是否达标;步骤S3、若所有测试性指标均达标,则给出的综合评估结论为达标,若存在设定类型试验的测试性指标评估结果未收集到,则进行基于外场数据的测试性指标自评估;步骤S4、根据所述测试性指标自评估获得测试性鉴定试验指标评估结果;步骤S5、若测试性鉴定试验指标评估结果达标,则给出的综合评估结论为达标。本申请给出的测试性指标综合评估方法,能够为测试性指标评价提供支撑,为测试性设计提升提供依据。
