A Study on the Reliability Evaluation of One-shot Systems according to Changes in Design Factors of Two Types

This study is for the design reliability sensitivity analysis of a one-shot system according to changes in two design factors.The study expands on the conventional logistic distribution-based regression analysis method, and proposes a new reliability evaluation method.Through applying the expanded method and the proposed method to the detonation test results of explosive bolts, the estimation accuracy was compared.Compared to the expanded method, the proposed method reduced the sum of squared errors by 30 percent, improving the accuracy in reliability estimation.Using the proposed method, the operation reliability estimation of the explosion bolt was predicted at a 99% confidence level.The proposed method could be widely used in optimizing design factors for reliability of one-shot systems. 2 . . . , 30% . 99% . .
