摘要
Tukey管制圖包含了數種特性：容易設置、使用個別值觀測監控製程、適合監控破壞性檢驗製程。在運用Tukey管制圖監控製程之前，管制界限寬度、抽樣間隔必須要決定。在這研究中，Duncan的成本函數被應用來建構Tukey管制圖的經濟性設計模式，以獲得最佳管制圖設計，此外，本研究在常態條件假設之下，建構Tukey管制圖的誤差機率計算方法，並將此誤差機率的計算應用到Tukey管制圖的經濟性設計模式中。最後，應用一個IC封裝的真實案例說明Tukey管制圖的經濟性設計模式的使用，從這案例的敏感度分析結果發現到，當管制內時間太短，或者的製程變異成本太大，都會明顯增加製程管制成本。

The significant features of Tukey's control chart include characteristics such as: easy setup, use of single observation to monitor process, and suitability to monitor destructive testing processes. The control limit width and sampling interval should be determined before Tukey's control chart can be used. In this study, Duncan's cost function is modified to construct an economic design model of Tukey's chart and to attain optimal design. Furthermore, methods of calculating error probabilities of Tukey's chart under normal conditions are constructed and applied in the economic design model. A real-world example of IC packaging illustrates the application of Tukey's chart to economics. The results of sensitivity analyses demonstrate that shorter in-control time or larger process variation cost incurs higher control cost.
