摘要为了节省更多的试验费用,研究了保证试验及其等效截尾序贯试验。在一种常用的情况下,以简洁的方式推导出了保证试验的工作特性(OC)函数和期望试验时间(ETT)函数。定义了等效检验及相关概念。建立了保证试验近似等效截尾序贯试验的构造方法。计算结果表明,本文提出的近似等效截尾序贯试验与保证试验的OC曲线基本一致。然而,它们可以大大节省ETT。结果表明,近似等效截尾序贯试验比保证试验分别节省约50%的ETT。
Abstract In order to save more test cost, assurance test and its equivalent truncated sequential test are studied. In a commonly used case, the operating characteristic (OC) function and expected test time (ETT) function of an assurance test are derived in a concise way. Equivalent test and relative concepts are defined. The procedures to construct a near equivalent truncated sequential test of an assurance test are established. Computation studies show that the near equivalent truncated sequential tests proposed in this paper keep almost the same OC curves with the assurance tests respectively. However, they can save the ETTs dramatically. In fact, the results show that the near equivalent truncated sequential tests can save around 50% of ETTs than the assurance tests respectively.
