摘　　要：本文主要提出了一个立足于当前实际的系统级诊断模型．在这模型下，系统级诊断变得很容易．模型基于下列假定：将系统划分成既具有自测试又具有测试其它单位能力的一种单位；其测试能力和测试结果用模糊数学来描述；自测试时在各种情况下均能给出正确的结果；测试其它单位时，除测试者本身具有严重故障外，也均能给出正确结果．In this paper, a diagnostic model of system-level based on practice is especially presented. Under the model, system-level diagnosis becomes very easy.This model is based upon the following assumptions: a system can be partitioned into units, and a single unit can individually test another unit and itself ; test capabilities and outcomes of units are described by fuzzy mathematics ; the test outcomes are always accurate during selftesting; the test outcomes are always accurate but the testing units have severe faults during a unit tests another unit.

关 键 词：系统级诊断 诊断模型 模糊数学 数字式
