Abstract

The diagnostic performance of modern avionic systems is widely characterized using anecdotal descriptors. 'Forty percent of all failures are due to switch/connector problems' and 'fifty percent of all equipment removed retests okay' are examples. While they are numerous and bear undeniable elements of truth, it is argued that their imprecision and fragmentary nature impede ready absorption of the information they convey into the diagnostic design process. The author asserts that these descriptors, taken in total, constitute a valuable, timely diagnostic requirements analysis input. He identifies a methodology for exploiting them, provides examples of the anecdotal inputs, presents interim and final analytical results, and proposes an approach to embedding the results into a diagnostic concept.<>
来自母猪的耳朵——来自轶事参考的定量诊断设计要求
现代航空电子系统的诊断性能广泛使用轶事描述符来表征。“40%的故障是由于开关/连接器问题”和“50%的移除设备重新测试正常”就是例子。虽然它们数量众多,并且具有不可否认的真理要素,但有人认为,它们的不精确和碎片性阻碍了它们传达给诊断设计过程的信息的及时吸收。作者断言,这些描述符,总的来说,构成了一个有价值的,及时的诊断需求分析输入。他确定了一种利用它们的方法,提供了轶事输入的例子,提出了中期和最终分析结果,并提出了一种将结果嵌入诊断概念的方法。
