摘要:

装备试验鉴定发挥着严把定型关口的作用,性能鉴定是其中的一个环节。数字化技术的发展带来了数字化试验的新形式,即研发数字装备随实装交付。针对数字装备的性能鉴定,确定试验样本量是试验方案设计的基础,由于数字装备的多输出参数和多鉴定方式,现有方法不能直接确定样本量,为此首先提出基于数字装备输出参数和实装等试验数据一致性检验的数字装备鉴定框架,然后给出只考虑实装试验方式下的最小试验样本量,再根据各种试验方式的关系进行样本等效和合并,最终得到鉴定所需的试验样本量。通过算例分析,说明了所提方法的有效性。

关键词: 数字装备, 性能鉴定, 试验样本量, 样本等效, 样本合并

Abstract:

Equipment test evaluation is to strictly control the type-approval processand the performance evaluation is one of the procedures to test the performance. With the development of digital technology, a new way is digital testing to deliver digital equipment together with the physical equipment. The sample size determination is basic for test design aimming at performance evaluation of digital equipment. Due to the huge output parameters and various testing ways, the existing methods fail to determine the sample size. Aiming at this problem, firstly, a framework for digital model identification is proposed based on the consistency test of digital equipment output and test data. Then, the minimum test sample size is calculated only considering the physical test. Next, sample equivalence and merging are performed based on the relationship between various test methods. Finally, the test sample size is obtained to support the evaluation. The effectiveness of the proposed method is demonstrated through example analysis.

Key words: digital equipment, performance evaluation, sample size, sample equivalence, sample merging
