Abstract:

In view of the large manpower and financial resources required for the maintenance test of the armored equipment of the army, as well as the long acquisition period of the maintenance test data, this paper focuses on the maintenance test method based on small sample size and establishes the maintenance test verification based on the Bayes small sample theory. Assessing the model and proposing an equipment maintenance test based on this method effectively reduces the number of samples needed to validate the indicators. At the same time, it is validated with the aid of model equipment maintainability tests. The accuracy is high, and maintenance and verification are reduced. The proposed method is of great reference value for reducing the cost of equipment testing and shortening the equipment development cycle in the development of army equipment.
