Kapur與Wang[2]於1987年已呈現一種短期線上品管系統之檢驗方法來設法降低運送給客戶產品的變異數，然而該模式並未考慮存在有檢驗誤差的問題。本研究將進一步提出考量具有檢驗誤差的修正的Kapur與Wang[2]模式來設定經濟規格界限，最後，並探討模式參數的敏感度分析。

Kapur and Wang [2] have presented that the inspection in an on-line quality control system conducts as a short term approach to reduce variance of the items shipped to the customers. However, they have neglected to consider the inspection error in the model. In this article, we further propose the modified Kapur and Wang's [2] model with inspection error for determining the economic specification limits. Finally, the sensitivity analysis of the parameters is provided.
