應用精實六標準差提昇面板模組廠製程效能
Application of Lean Six Sigma Process to enhance the Performance of TFT-LCD Module Factory
摘要
台灣產業面對全球化競爭、產品生命週期縮短、多樣少量、快速交貨等各式的壓力下，許多企業莫不希望藉由精實六標準差的實施或導入，發掘和改善傳統生產的盲點。藉由消除流程中的浪費，減少不必要的投入，以強化供應鏈的整體能力，達到縮短在製時間、減少搬運、節省人力、降低產品成本，並且改善品質、縮短交期、提升客戶滿意度等目標，協助企業增強競爭力。 本文探討精實六標準差導入實施的程序與步驟，並以面板模組廠為案例，以驗證精實思想體系的效用。運用精實六標準差之改善手法進行製程專案改善，首先運用價值溪流圖找出無價值之改善點，再進行縮短作業時間以提升產能。本研究詳細說明所使用的各種工具與手法，經由「現狀價值溪流」到「未來價值溪流」的程序與步驟，說明改善現狀價值溪流所引進的管理技術與方法。此案例結果驗證精實六標準的改善方法，在工廠持續簡化生產流程與提升生產效能，降低生產成本及浪費上，具有實質效果。

Industries in Taiwan had to face so many challenges such as global competition, product life cycle shortening, various small orders, and less production lead time. Lean six sigma (LSS) method was utilized by many manufacturers as an effective management solution, many companies thought the implementation of lean manufacturing might discover and improve blind spots of the existing production system. Eliminating waste in the workflow and reducing unnecessary efforts will enforce the capability of the overall supply chain. In such a case, the cycle time and material handling time may be shortened, the labor cost may be reduced, and the production cost may be decreased. Therefore, the goal of quality improvement, shorter deliver time, and higher customer satisfaction can be reached and enterprises will enhance their competitiveness. This research discussed the implementation processes and procedures of the LSS, and the case study of a TFT-LCD module factory was illustrated to verify the effectiveness of LSS method. The DMAIC process was applied to improve manufacturing processes, and the value stream map (VSM) was used to find out non-value points in the processes, operation times were decreased to improve productivity. This research described applied methods and tools in detail, and also discussed the process and technique of transforming the current value stream to the future value stream in depth. The project results showed that the throughput of the module factory was increased with the same quality level; therefore, the production cost of the plant was decreased, and the effectiveness of the LSS method was verified.
