Abstract: As the natural fault samples are insufficient in the field test and the evaluated result of the laboratory test is superior to the real testability level of the equipment, a scientific evaluation method of testability is lack for armored vehicles in final stage. For this reason, the test predictive model of testability is modified according to the definition of conditional probability, and the relationship between the test result and the test evaluation mode is studied. A comprehensive test method of testability based on the three test modes, including field test, laboratory test, and analysis and evaluation, is presented, and a calculation model of test result credibility and a comprehensive evaluation model of testability, which determines the weight of different test results according to credibility, are established. The proposed method and models are validated via applied examples. Results show that the comprehensive testability evaluation method based on the credibility of the test results solves the problem that the samples of field test are insufficient and improves the practicability of test operation and the scientificalness of evaluation conclusion.
