摘要: 以定时截尾验证试验方法为例,利用Beta分布函数的概率特性,将抽样函数所表示的接收概率转化为F分布的下侧分位数。建立了验证试验中产品可靠性进一步推断的估计方法,并利用验证试验数据中所包含的产品可靠性信息,求出了验证指标在给定置信度下的单侧置信区间估计值。最后通过数值模拟计算验证所提出的产品可靠性,进一步推断方法的正确性。

Abstract: For demonstration testing of type-I censoring, using the probability properties of β distribution function, transfer the acceptable probability expressed by sampling function into the lower fractile of F distribution, set up a formula which can be used to further estimate the product’s reliability characteristic parameter. Using reliability information of test data in demonstration testing, obtain estimation value of one-side confidence limit for reliability characteristic parameters at the given confidence. The validity of the above method is verified by numerical simulation computation.
