隨著LED產業蓬勃發展，未來中國可望為全球LED照明最大市場，且LED看板目前是中國最成熟的LED應用之一，由於進入門檻低，全中國約有數千家公司投入LED的領域中。但在不斷地建廠、擴廠的同時，也導致全球LED產業供過於求的現象，當地廠商不斷以降價搶單，也使中國LED商機看似前景亮麗，但廠商卻還沒吃到商機，就先殺價、倒閉。由於LED供過於求的市場並不只影響中國，連帶著台灣多家LED廠商也處於虧損狀態，因此本文將探討在當前環境如此不利的情況下，台灣廠商對供應鏈內外部之需求該如何抉擇。 模型將以高科技產業中常見的多階段、多廠區之供應鏈網路問題，並於前人所作之基礎模型加以延伸，並不局限於供應鏈內部之需求訂單(晶粒之一般性與策略性訂單)，也將對手外包之磊晶片需求訂單(磊晶片之一般性與策略性訂單)考慮進來，期望能於經濟不濟之環境中改善企業虧損之情況。而其研究模型最主要目的為，加入新的銷售路徑並產生供應鏈策略性規劃產能應用之決策準則，以供管理決策者參考。 With the rapid development of Light Emitting Diode (LED) industry, China is expected to be the world's largest LED lighting market. As the China LED industry low barriers to entry and the LED billboard is one of the most mature applications, there are thousands of companies to enter the field. But the LED industry to promote fast cause global LED industry oversupply, local manufacturers continue to reduce prices to snatch orders, which makes China's LED market prospects look bright, but the manufacturer has yet to seize business opportunities, they begin to reduce the price and collapse. LED market oversupply does not only affect China, even with many Taiwan's manufacturers suffer losses. Therefore, this research focuses on exploring the issue of Taiwanese manufacturers how to choose the internal and external orders in the current challenging supply chain environment. The research model uses the previous LED supply chain base model to be extended, and the model situation is common in high-tech industry, multi-stage, multi-plant supply chain network problem. It is not limited to the demand within the supply chain orders (chip of general and strategic customer orders), but also taken into the wafers orders of opponent's outsourcing (wafer of general and strategic customer orders).The main purpose of the research model is adding new sales paths and generating decision criteria of strategic capacity planning to apply for management decision makers.
