摘要: 针对成败型产品生产定型阶段的可靠性验收问题,为了合理综合利用产品定型阶段以前的先验信息,利用竞争失效方法建立了产品定型阶段和批生产阶段的可靠性信息转换模型,进而确定了批产品生产可靠度的先验分布。在此基础上,给出了其后验分布、风险的计算方法以及Bayes验收方案的制定方法。实例分析表明,该方法能够大大减少验收试验量,且方法稳健。

Abstract: For the acceptance test of binominal products in the production definition phase, an information transition model for type approval phase and batch production phase is established using competition-failure method in order to properly use the prior information of the type approval phase. The prior distribution of batch products’ reliability is presented. On this basis, the calculation method of posterior distribution and risk is given, and a Bayesian acceptance test scheme is proposed. The experimental results show that the proposed method can be used to enormously reduce the acceptance test, and has preferable stability.

Key words: mathematical statistics, reliability, acceptance test, Bayesian method, binominal product, batch production
