摘　　要：合理确定评价指标及分配指标权重对故障样本评价至关重要,文章在综合考虑测试性验证试验目的和考核内容的基础上,提出一种基于扩展多信号模型的故障样本可拓评价方法;方法基于扩展多信号流图构建故障样本评价的指标,结合可拓学理论,建立基于平均故障关联度的故障样本集可拓评价模型,并对某型机载数传测试性验证试验故障样本进行评价;研究结果验证了所提方法的有效性。Determining the index and allocating the index weight reasonably are important for evaluation of fault sample. Based on synthetically considering the aim and assessment content of testability demonstration test, a method of Extenics in fault sample evaluation based on extension multi--signal model is put forward. In the method index of fault sample evaluation is established based on extension multi--signal model, and a evaluation model of fault sample based on average failure correlation and extensional theory is built. The model is applied to evaluate the fault sample of for testability demonstration test. Research results show the effectiveness of the proposed method.
