在多階段生產系統的檢驗策略研究中，對於在檢驗後發現有缺陷的半成品，如果後續作業流程為缺陷修補，通常假設修補率為固定值。在研究中比較少探討如何有效提升修補率的方法。本研究主要在探討如何在有限的修補資源條件下，取得最大的缺陷修補成功率。研究中會考慮工廠修補機台的數目為固定，且有修補產能需求的條件下，探討如何決策各修補站的單顆缺陷修補上限時間之最佳化組合，取得總體缺陷最大的修補成功率。期望研究結果能發揮修補機台的最大效率，滿足修補產能需求，並提供最佳的出貨品質。
本研究以彩色濾光片(Color Filter)工廠為例，彩色濾光片的製造系統屬於多階段生產系統，且有多個的缺陷修補站。因工廠有最少產能滿足的需求，以現有的缺陷修補機台數量無法對生產中所有的缺陷進行修補，因此有些半成品的缺陷未修補就進行下一道製程，造成良率損失。因此本研究此問題探討如何提升修補機台效率，增加總體缺陷修補成功率。在現實中彩色濾光片中的缺陷修補完成所需的時間是不固定的，因此修補機台可能會花過多的修補時間在不易修補的缺陷上，造成總體缺陷修補效率不佳。所以研究中提出以設定單顆缺陷的修補上限時間方式，增加總體缺陷修補成功率。研究中以修補上限時間為決策變數，另外案例中會有多個修補站，所以會有多個決策變數的組合，這增加求解的困難性，此外在研究中還到考慮實際缺陷發生為隨機性及修補時間的不固定性，增加了問題的複雜度，這使問題不易用傳統的數學方式求解。根據文獻探討，當系統有隨機性且複雜時可利用系統模擬最佳化會減少求解的時間，且有不錯的求解品質。因此本研究方法會以系統模擬軟體Arena 建模，並以OptQuest最佳化來求解。使模擬結果能依實際狀況，調整參數，模擬演練並實際應用。

TFT-LCD is an important technology industry in Taiwan. Because the strategy of continuous expansion of panel manufacturers, the panel market demand is gradually saturated. Therefore, the panel makers are now paying more attention to the development of high-standard and high-quality products, rather than capacity competitions. The thesis is to study the method of improving defect repair rate of TFT-LCD semi-finished products, color filters (CF). Under the current configuration of the existing repair machine, this paper studies how to increase the repair rate of the total defect by limiting the upper limit of defect repair time. CF is a multi-stage manufacturing system. There will be a repair station after each major processing station. The number of defects and the difficulty of defect repair in each process station are different, and the defects are generated as random. According to literature, when the problem is complex and the data is random, simulation methods can be used to find the optimal solution effectively. This study uses simulation methods as a tool, by OptQuest software gain optimization solution. It is expected to find the upper limit of repair time for each repair station and increase the repair rate of total defects. This study can provide managers with reference to repair decisions.
