Reliability Demonstration Testing Procedure for Weibull Distribution

讨论了Weibull型产品的可靠性验证问题 ,首先分析了Weibull型产品分布参数的无信息验前分布问题 ,利用验前信息可以得到分布参数的验前概率密度函数 ,进而分析了产品的可靠性验证问题 ,顾及了使用方利益和生产方利益。仿真算例表明 ,使用方利益和生产方利益是相互折衷的。

The reliability demonstration testing procedure for Weibull distribution is discussed. First, the noninformative prior distribution of the parameters of the life distribution is derived. Then the prior PDF(Probability Density Function) of these parameters are given combining with prior information according to Bayesian theorem. Finally, the reliability demonstration testing procedure is analyzed taking into consideration the consumer's profit and producer's profit. The simulation results show that the consumer's profit and producer's profit can be compromised.
