摘要： 多信号模型是一种简单而有效的系统建模表示方法，已被美国QSI公司引入其TEAMS(测试性工程和维修系统)软件中，用于系统测试性分析和预计、可靠性分析以及故障诊断等。对基于多信号模型的系统测试性建模与分析方法进行深入研究，结合示例具体给出多信号模型的表示和建模，故障-测试相关矩阵以及未检测故障、模糊组、冗余测试、故障掩盖、故障检测率和故障隔离率等的具体分析过程和算法。算法分析结果与应用TEAMS软件分析结果相一致。基于多信号模型的测试性分析方法，虽然不能给出一个全面的测试性评定结论，并存在着不足之处亟待改进，但易于实现计算机辅助分析，对系统测试性设计工具的研发具有价值。

Abstract: Multi-signal modeling methodology is a simple but efficient knowledgerepresentation method which has been adopted in the application of TEAMS by ASICompany in U.S. for testability analysis, testability prediction, reliability analysis and fault diagnosis. Research on modeling and analyzing method of systemtestability based on multi-signal model is carried out. Combining illustrations, analysis process and algorithm of multi-signal modeling, fault-test dependencymatrix, undetected faults, ambiguity group, redundant tests, fault masking, FDR, FIR, etc. The result of the above algorithm is the same as the one of TEAMS. Though testability analysis based on multi-signal model can not offer a comprehensive conclusion and have defects to improve, it is easy to implement computer aid analysis, which is valuable for development of system testability tool.
Key words: multi-signal model    testability modeling    testability analysis
