基于通用充分性准则的测试性试验方案研究

建立了故障模式与被测单元(UUT)特性之间的关系模型,根据关系模型建立了样本集的通用充分性准则。在通用充分性准则的基础上,研究了确定试验方案的新方法,包括确定样本量和建立样本集的方法,以及相应的合格判断方法。通过实例应用说明了方法的可行性。与现有方法相比,新方法更适用于现有的指标要求情况和多参数综合试验的需求,而且建立的样本集可以覆盖UUT的重要特性。

Study on the Plan of Testability Demonstration Based on the General Adequacy Criterion

The relation model of failure modes and characters of the unit under test(UUT) is created.The general adequacy criterion for the sample set is proposed according to the relation model.Based on the general adequacy criterion,the new method for determining the demonstration's plan is studied,which includes the methods for determining sample size and creating sample set and the pass judgement.A case shows the feasibility of the new method.Comparing with the exist methods,the new method is more suitable for the exist state of the testability requirements and the integrative demonstration of multiple testability requirements,and the created sample set can coverage the important character of UUT.
