Abstract

This paper deals with a common problem in the reliability testing of aviation products—reliability assessment with zero failure data. Because the conventional method is excessively conservative, a reliability estimation method that introduces the lifetime dispersion of expert judgments is proposed in this paper. It is defined as the ratio of the maximum lifetime with a probability of 99.73% to the minimum lifetime. The performance of the proposed method is analyzed and compared with the conventional method through a Monte Carlo simulation study. The results show that the proposed method is superior in accuracy and robustness. In particular, the method performs better in the reliability assessment of aviation products. Finally, an application case study is conducted to illustrate the application of the proposed method.
