摘要
鉴于用户对航电产品测试性要求的不断提高,因此在签署协议时已经规定了产品的测试性定量指标以及开展测试性建模和测试性验证试验的要求。首先收集产品测试性设计信息,梳理产品研制阶段开展测试性建模分析的流程,根据测试性建模的结论以及改进建议迭代产品设计,再开展测试性试验验证测试性建模分析的正确性,对改进后测试性设计进行验证,以实现产品的测试性设计迭代与增长,判定产品的测试性水平是否达到规定的要求。
At present, testing requirements of the user on avionics products have improved, and the testing quantitative index of the product and the requirements of the testing and testing are clear. First, collect the information of product testing design and analyze the process of the testing in the development phase of the product development phase according to the conclusion of the test model so as to improve the design of the proposed iterative product. And then carry out test to verify the correctness of the test model analysis, the improvement of the test design is verified, in order to achieve the product＇s test design iteration and growth, determine whether the product＇s test meets the requirements.
