TFT-LCD(Thin Film Transistor Liquid Crystal Display；薄膜電晶體液晶顯示器)之直接材料佔總成本約60%~70%的比重，台灣面板廠在面對日、韓的激烈競爭下，皆致力於降低成本增加競爭優勢，因此，台灣面板廠(如友達光電、奇美電子以及群創光電)紛紛要求其協力廠商實施供應商管理庫存(Vendor Managed Inventory, VMI)政策，也就是由供應商在適時補充面板廠所需要的數量，面板廠再根據實際使用數量，支付供應商的貨款。
然而，在所有TFT-LCD零組件中，驅動IC補貨之前置時間最長，且由於液晶面板近年來出貨量增加，以及消費者追求高畫質，高解析液晶電視逐漸成為市場主流，刺激了驅動IC之需求，因此本研究以某大面板廠及其驅動IC供應商為研究對象，以Yao et al.(2007)所建構之供應鏈管理模式及VMI模式，並增加成本模型，探討各項重要參數(平均需求強度、需求的變異性、前後期需求相關係數、補貨頻率以及供應商補貨之前置時間)的變動在實施VMI後，分別個案面板廠及驅動IC供應商存貨成本的影響，並說明其管理意涵，最後，以田口方法分析尋找出最適參數組合及重要因子，期望能提供業界制定VMI相關決策與制度時之參考。

The components of the Thin Film Transistor Liquid Crystal Display (TFT-LCD) account for 60%~70% of its total cost. Facing the fierce competition of panel plants in Japan and Korea, panel plants in Taiwan make great efforts to reduce the cost in order to improve their competition. Therefore, panel plants in Taiwan, such as AUO, CMO and Innolux all request their vendors or suppliers to implement the Vendor Managed Inventory (VMI) policy. To be more precise, suppliers should replenish the demand for the components to panel plants in time, and the payment is made according to the actual demand.
The lead time of the replenishment for Driver IC is the longest among the other components of TFT-LCD. Moreover, the demand of Driver IC is boosted due to the increase in the shipping quantity of the TFT-LCD panels in recent years and the customer’s preference for high-resolution screens leading to TFT-LCD Televisions with high resolution, the mainstream product in the market. Accordingly, one of panel plants and Driver IC suppliers is set as the subject of the research, and the research paper will discuss the variance of each important parameter including the mean demand, the residual demand variance, the autocorrelation in demand, replenishments per period, and the lead time based on the supply chain management model, the VMI model developed by Yao et al. (2007), and also added the cost model in analysis. After VMI is implemented, how it influences the inventory cost for the panel plant and the Driver IC supplier is analyzed and the significance of VMI is explained. The study provides a good approach to find out the most suitable parameter compound and other noticeable factors through Taguchi Method, which can be applied while the industry is making VMI-related decisions and policies.
