Abstract:

Aeronautic equipment should take a series of tests in its development phase, and its reliability is continuously improved. Therefore, The use of all these test data to evaluate the system reliability growth could effectively improve the evaluating accuracy. But first of all it should solve the varied environment problem, that is, in the test, various environments produce various data. This paper brings forward a kind of integrated reliability growth evaluation model. By using environment conversion factors the model can convert the test data from various environments into those from the same environment and afterwards analyze the system reliability improvement to make a correct evaluation. In the end, an example presents the model's engineering practicability.

Key words: development phase, reliability data, reliability growth, reliability evaluating
