飞行器测试过程中测试项目复杂,测试数据较为稳定,测试价值较低。该文针对飞行器测试价值评估方法进行研究,提出一种基于历史数据的飞行器测试价值评估方法,为简化测试项目提供理论依据。该方法对飞行器历年来测试数据进行归一化处理,分别利用标准差法和熵权法获得各项测试参数的客观权重,采用退化模型对测试参数进行二次修正,最后依据D-S证据理论,对各参数进行融合,获得测试项目的测试价值。将该方法应用于某型号飞行器测试中,结果表明对测试价值量化评估较为准确。
Test items in the aircraft testing process are complex, the test data is more stable, and the test value is lower. In this paper, the method of aircraft testing value assessment is studied, and a method of aircraft testing value assessment based on historical data is proposed, which provides a theoretical basis for simplifying the testing project. The method normalizes the test data of the aircraft over the years, obtains the objective weight of each test parameter by using the standard deviation method and the entropy weight method respectively, and applies the degradation model to the secondary correction of the test parameter. Finally, according to DS evidence theory, The parameters of the fusion, test items to get the test value. The method is applied to a certain type of aircraft test, the results show that the quantitative evaluation of the test value is more accurate.
