摘要

Chen於2006年提出一考量產品在規格界限內具品質損失的修正Pulak與Al-Sultan模式以獲取最佳製程參數，然而，其模式並未考慮檢驗誤差存在的問題，本研究將提出具檢驗誤差的修正Chen模式來求解最佳製程平均數與經濟規格界限，最後並比較兩模式間解的差異。

並列摘要

In 2006, Chen presented a modified Pulak and Al-Sultan's model with quadratic quality loss function of product within the specification limits for determining the optimum process parameters. However, he did not consider the problem of inspection error. In this paper, the authors propose an integrated model for obtaining the optimum process mean and economic specification limits based on the modified Chen's model with inspection error. Finally, the numerical results and sensitivity analyses of the modified Chen's model with inspection error and those of Chen's model without inspection error are further provided for illustration.
