摘　　要：在复杂航空电子装备的故障诊断中,经常存在某项测试信息丢失或不确定的情况。针对该问题,建立了复杂航空电子装备的测试信息不完备故障诊断信息系统,利用最大分布约简集获得不完备测试信息的最优选择;针对最优选择的不唯一性,提出一种改进的不完备测试信息最优选取方法。以某型雷达系统的不完备测试信息系统的诊断规则提取为例,验证了该方法的有效性,表明使用该方法可提高在测试信息不完备条件下对复杂电子装备实施故障诊断的效率。When diagnosing the fault of complicated avionics, there is always the condition lacking of test information or existing uncertainty. To solve this problem, the fault diagnosis information system lacking of test information was found, and the most excellent choice of incomplete test information was got with the help of the largest distributing reduction concourse. To eliminate the non-uniqueness of the most excellent choosing, a ameliorate method of the most excellent choice lacking of test information was put forward. Taking the diagnosis rule distilling of imperfection test information system of a radar system for example, the validity of this method was validated. Finally the experimental results show that this method can improve the efficiency of diagnosing the fault of complicated avionics in lacking of test information condition.
