近年來液晶顯示器(Liquid Crystal Display)蓬勃發展，而在薄膜電晶體液晶顯示器(Thin Film Transistor-Liquid Crystal Display, TFT-LCD)產業中縮短產品設計開發時間是最重要的競爭優勢之一。其中產品設計驗證測試階段(Design Verification Testing, DVT) 是產品設計開發中費時最久的部分，對於公司決定可大量生產的時間以及給予客戶的交期有相當大的影響。為了縮短產品設計開發時間，在符合高標準的品質控管條件下快速滿足客戶端的出貨要求，本研究針對TFT-LCD新產品設計驗證測試流程之特性進行流程改善變更，使部分活動同步進行，加速新產品設計驗證測試流程進入放量生產階段，並有效縮短客戶交期，增加市場競爭力。本研究利用數學模型推導，計算使用傳統流程與同步流程時完成產品設計驗證測試階段所需的平均時間，並繪製其分配，計算存貨損失風險機率，以便公司評估使用同步流程所獲得的利益並與其所產生的風險相比較以決定是否使用同步流程。最後，本研究透過研究三種不同生產情境以推論在什麼情形下應該使用同步流程，及其前端製程最適放量決策點，做為公司決策放量之參考。

Short product development lead time is one of the most important competitive advantages in TFT-LCD industry. Design Verification Testing (DVT) process accounts for much of this lead time. In this research, we propose a new DVT process by overlapping some of the activities to shorten the product development lead time. In addition, we develop mathematical models to evaluate the expected DVT times of both original and overlapped DVT processes as well as the probability of inventory lost for the overlapped process. By comparing the expected product development lead times of these two processes against the risk of inventory loss of the overlapped process, the company can evaluate the benefit of adopting the overlapped process against its potential risks. Three product types are studied to determine the conditions under which the overlapped process is preferred. Once the overlapped process is adopted, the optimal date to release production order for front-end process is also studied.
