本文提出不完全生產系統中基於考量完全重做過程的修正Chen and Chung模式，文中採望大特性的二次品質損失函數來量測產品的品質，修正模式係藉由獲取最大的平均總利潤方式來設定最佳的生產時間長度與製程平均數。研究結果顯示，需求數量與產品價格對每單位時間平均總利潤有重大影響。

In this paper, we proposed a modified Chen and Chung's model based on considering the perfect rework process in the imperfect production system. The quadratic quality loss function for larger-the-better characteristic will be used for evaluating the product quality. The optimum production run length and process mean will be jointly determined for obtaining the maximum expected total profit. From numerical results, the conclusion is obtained as follows: the demand quantity and the selling price have the major effect on the expected total profit per unit time.
