中止规则的平均延迟时间及其应用

The Average Delayed Time of Stopping Rules and Its Applications

本文以平均延迟时间为度量，对适用于连续抽样方案的四种中止规则，即规则［Ｓ］，［Ｒ］，［Ｎ，ｃ］及［Ｒ，ｄ］的中止“速度”进行了比较。结果表明：［Ｒ］优于［Ｓ］，而［Ｎ，ｃ］与［Ｒ，ｄ］均优于［Ｒ］。这些结论及方法可被用来适当地选择中止规则。

By introducing the measure of average delayed time, the stopping‘velocity’ are compared among four kinds of differental stopping rules, including rule,,and,each of them can be adopted as a part of operating program in continuous sampling plans. It is indicated that rulevastly excels rulein stopping characteristics while both ruleand excels. These conclusions and measure may be conductive to select the appropriate stopping rule for quality control in continuous production.
