Abstract:

The reliability acceptance test is to check whether the product meets the reliability requirement. It is essential to choose a test plan with controllable customer's and producer's risks. However, the reliability acceptance test adopted from GJB899A oftentimes leads to either long test duration or high customer's and producer's risks, which hinds its real-world application. The primary reason lies in that, only the test data collected from the systems are taken into account, whereas the information from experts is ignored. Considering there are various types of expert information and the system life follows the Weibull distribution, the two types of risks of the product can be calculated. Then the test plan with shorter test time and controllable risks can be determined. The proposed method is applied to a numerical case study and the results verify the effectiveness of the method.

Key words: Weibull distribution, expert information, producer's risk, customer's risk, reliability acceptance test
