摘要
在可靠性定型试验的基础上,利用多层贝叶斯方法确定批产品可靠性指标的先验分布,从而制定出成败型产品可靠性验收试验的一种贝叶斯方案.给出利用定型试验信息确定产品可靠性指标先验分布的方法.这种验收方法充分利用了产品定型试验中的先验信息,在确保有较好验收效果的前提下,与传统的验收试验相比,可以大大减少试验量,从而得到可观的经济效益.
Based on the test for reliability appraisal, the hierarchical Bayesian method is used to decide the prior distribution of the reliability indices, so that a new Beyesian sampling scheme is got for success or failure mould product in the acceptance test. Thereby, the prior information in the product type test is utilized more sufficiently, and the volume of test work is reduced considerably in comparison with the traditional acceptance test under presupposition of quality assurance. Furthermore, the economical effect is gained.
