近年來在台灣政府的支持與鼓勵下，使台灣的薄膜電晶體液晶顯示器（Thin Film Transistor Liquid Crystal Display，TFT-LCD）產業蓬勃發展。在面臨顧客需求波動難以預測、面板尺寸與解析度的技術不斷推陳出新及全球化競爭的高度壓力下，對於追求低成本、高製造彈性、高品質與服務水準的TFT-LCD製造商而言，紛紛將精實系統的概念導入生產系統中以提升生產效率與降低生產成本。
精實系統提倡持續改善、消除浪費，由於TFT-LCD末端製程的模組組裝（Module）為勞力密集的產業，若未妥善規劃標準作業，或未適當分配作業者的作業內容，容易形成人員閒置時間過長的浪費，因此本研究將針對作業面進行改善，消除生產過程中人員閒置的浪費，並以TFT-LCD模組組裝製造商為案例探討對象；在考量製程限制下，以少人化模式為基礎，發展單元工程設計邏輯，並結合混整數規劃數學模型，尋求總作業者人數的最佳化，以達到少人化效益。其中本研究是以柳生俊二（2009）提出的「少人化思考模式」為基礎，結合Rother and Harris（2001）撰寫的《Cerating Continuous Flow》一書中繪製作業者平衡圖的原則，作為本論文導入少人化模式的依據。而實驗情境設計主要為尋找績效表現最穩健的少人化模式方案，由SN比衡量實驗結果發現，導入少人化模式的績效表現較未導入佳。因此製造商可透過導入少人化模式來提升生產效率與降低生產成本，以增加其產業競爭力。

With the assistance of the Taiwan Government, the TFT-LCD industry in Taiwan is getting more flourished. Its processes are composed of array, cell and module. However, TFT-LCD industry faced the pressure of unpredictable customer’s demand, technology progressing, and competitive global market. For the TFT-LCD industry, the low cost, high manufacturing flexibility, high quality and good service are all need to be concerned. Recently, some concepts of the lean system are introduced into many companies to enhance the production efficiency of production systems and decrease production cost. Lean system emphasizes that companies should continue improving it’s capability and reducing wastes. Because the main capacity in the module process of TFT-LCD industry is manpower, we should plan standardized work and assign tasks to the operators appropriately or it may cause much idle time of operators.
To deal with the problem, this paper considers the thinking of labor linearity to developing the logic of cellular design under the limitations of process and industry characteristics at first. The basic concept of the thinking of labor linearity in this paper comes from Yagyu (2009), and we progress it by adding the concepts of operator balance chart from Rother and Harris (2001). Then, we construct the mixed integer programming formulation to solve the optimal number of total operators. In this way, we can obtain the benefit of labor linearity by reducing the idle time of operators. The experiments are composed to verify the benefit of introducing the model of labor linearity in the TFT-LCD module industry. By comparing Signal-to-Noise ration, the result shows that using the model of labor linearity make the performances to be better. Hence, the manufacturer can improve the production efficiency of production systems and decrease production cost by introducing the model of labor linearity to enhance the competitiveness.
