Until now, various acceptance reliability sampling plans have been developed based on different life tests. In most of the reliability sampling plans, the decision procedures are based on the lifetimes of the items observed on tests, or the number of failures observed during a pre-specified testing time. However, frequently, the items are subject to degradation phenomena and, in these cases, the observed degradation level of the item can be used as a decision statistic. In this paper, assuming the gamma degradation process, we develop a variables acceptance sampling plan based on the information on the degradation process of the items. It is shown that the developed sampling plan improves the reliability performance of the items conditional on the acceptance in the test and that the lifetimes of items after the reliability sampling test are stochastically larger than those before the test. A study comparing the proposed degradation-based sampling plan with the conventional sampling plan which is based on a life test is also performed.

基于退化试验的变量验收可靠性抽样方案

到目前为止，已经根据不同的寿命测试制定了各种验收可靠性抽样方案。在大多数可靠性抽样计划中，决策程序基于在测试中观察到的项目的寿命，或在预先指定的测试时间内观察到的故障数量。然而，物品经常会出现退化现象，在这些情况下，观察到的物品退化水平可以用作决策统计量。在本文中，假设伽马退化过程，我们根据物品退化过程的信息制定了一个变量验收抽样计划。结果表明，所制定的抽样方案提高了以试验验收为条件的项目的可靠性性能，可靠性抽样试验后的项目寿命随机大于试验前的寿命。还进行了一项研究，将提议的基于退化的抽样计划与基于寿命测试的传统抽样计划进行比较。
