2023年2月7日 · 五种最常见的测量方法是 每单位缺陷（dpu） 、 每百万次机会中的缺陷（dpmo） 、 每个机会中的缺陷数（dpo） 、 每百万个中的不良个数（dppm） ，以及 rty（直通率） 。

Defects per million opportunity (DPMO) is a measure of occurrence of defects per million opportunity. It is calculated by the formula shown in the picture below. Here D is the No of defects observed, S is the sample size and O is the no of opportunities for defects per unit.

2019年7月24日 · I'm trying to calculate a DPMO rate however when I introduce my formula the result is completly different that what I expect. The math of the DPMO es easy, just (Total defects*1000000)/samples taken . so, anyone of you could help me on this? thanks in advance

2018年2月24日 · σ是一个希腊字母，读作“西格玛”，在数理统计中表示“标准差”，是用来表征任意一组数据或过程输出结果的离散程度的指标，是一种评估产品和生产过程特性波动大小的参数。 西格玛质量水平则是将过程输出的平均值、标准差与质量要求的目标值、规格限联系起来进行比较，是对过程满足质量要求能力的一种度量。 西格玛水平越高，过程满足质量要求能力就越强；反之，西格玛水平越低，过程满足质量要求的能力就越低。 六西格玛质量水平意味着百万出错机 …
