摘要:

为了解决长寿命、高可靠性产品在可靠性验证试验中面临的耗时长问题,本文以寿命服从指数分布的产品为研究对象,提出了一种基于相似产品先验的Bayes可靠性验证试验方案设计方法。首先,引入贝叶斯方法,将同类型产品的试验数据作为先验信息,采用拟合优度检验统计量量化产品之间的相似性,进一步利用继承因子实现先验分布的计算。随后,运用贝叶斯平均风险准则计算实际的生产方和使用方风险。最后,通过迭代方法求解最优的可靠性验证试验方案。实验结果表明,与GJB899A-2009标准中的可靠性验证试验方案相比,本文方法可显著缩短试验时间。

Abstract:

To address the prolonged duration associated with reliability demonstration tests for long-life and high-reliability products, this paper focuses on products whose lifetimes follow exponential distributions and proposes a Bayes reliability demonstration test (RDT) design method incorporating prior information obtained from similar products. Firstly, the Bayesian method is introduced into the RDT design. Concretely, the experimental data achieved from similar products is viewed as prior information. The similarity between any two products is quantified by goodness-of-fit test statistics, and prior distribution is calculated through an inheritance factor. Secondly, the Bayes average risk criterion is utilized to describe the risks for both the manufacturer and the consumer. Finally, an optimal RDT plan is obtained through a numerical iteration method. Compared with the RDT plan in the GJB899A-2009 standard, the experimental results exhibit that the devised method can significantly reduce the test time.
