[討論]抽樣計劃與管制圖的關係

RELATIONSHIP of SAMPLING to CONTROL CHARTS
抽樣計劃與管制圖的關係

Shewhart Control Charts are not Acceptance Plans
舒華特的管制圖並不是允收計劃
Shewhart Xbar and R charts analyze processes that involve a series of lots produced over time. They concern the relationship of the subgroups to each other, and not to any externally imposed specification. Use Xbar and R charts to discover the factors that contribute to process variability.
Shewhart charts cannot ensure against accepting poor or recallable lots. Even an in-control characteristic can have a substantial fraction of non-conformities. Xbar and R charts do not control the consumers risk (ß) of accepting RQL or recallable lots.
舒華特的平均值與全距管制圖分析的是包含了一系列LOT的連續性制程，它關心每個分LOT之間的連系，而不是外部的影響。它揭示了引起制程變異的因素，但不能確定是否允收一個有可能不良的批次。因為即使是一個良好控制的圖表也可能包含其實是不符合的部分(產品)，換句話說，Xbar-R圖無法管控接收RQL批的貝塔風險。
Acceptance Control Charts.
允收控制圖
Acceptance control charts are acceptance sampling plans that you convert into chart form for implementation. They control the producers point and the consumers point of the oc-curve. Acceptance charts provide a valid visible means for making acceptance sampling decisions.
允收控制圖是轉換為圖表格形式的允收抽樣計劃 ，它包含了OC曲線中的生產者指數和消費者指數，允收圖 提供了一個有效的可視化的方法來決定允收的抽樣計劃
Acceptance Sampling for Acceptance Decisions
允收的抽樣計劃
The best way to make the accept/reject decision - whether a process is out-of-control or
in-control-is to use both the producer's risk and the consumer's risk. In other words, honor both the process capability and the product specifications.
最好的允收(判退)計劃即要考慮到生產者的風險又要考慮到消費者風險(不管制程是否在管控之內)， 也就是說，同時考慮制程能力及產品規格

很簡單的教材上的，
不知翻的對不對，請各位指點呵
不過那個允收控制圖，不知所謂的說。。。。。。。。
