隨著近年來大環境的改變，許多企業為了提高營收獲取更多的訂單，持續不斷的藉由併購與擴廠等方式來增加產能，而隨著企業產能規模的擴增，提升了企業整體的競爭力，企業也希望藉此獲得更高利潤，因此企業都希望能藉由跨廠區之間的產能規劃及調配以達到利潤最大化及產能最大化的目標，因此如何利用跨廠區之間的產能規劃及調度來提升企業獲利成為一個重要的策略，但目前大多數的企業還是以過去的經驗在進行這些活動。因此如何將多廠區的產能作最適的規劃，達到最有效的利用率與最低的成本，同時要能滿足顧客的需求，正是本研究的目的。
本研究將以線性規劃模型為基礎求解 TFT-LCD 產業在產品需求與產能限制下多廠區的最佳生產計畫，過去相關求解 TFT-LCD 產業的多廠區規劃之問題，大多僅探討如何將成本壓在最低或是將獲利達到最大，本研究將加入另一限制，即公司於策略性的考量，公司策略性的考量有可能會造成成本提高或獲利降低，但這會是更貼近讓整個 TFT-LCD 產業在多廠區的規劃的實際狀況。

This study investigates multi-site operations of TFT-LCD manufacturing. In recent years, TFT-LCD manufacturers receive more orders within a short period than before. Merging and expanding is an effective ways to enhance their competitive advantages and increase their revenues. Manufacturers who expand their business for multi-site operation would consider important factors, such as site balancing, resource sharing, and allocation planning. Most TFT-LCD manufacturers currently use the rule of thumb to deal with multi-site operation issues, such as how to achieve high utilization with aims to minimize the cost and obtain the optimal allocation plan under multi-site operations. This study uses linear programming to solve the problem of multi-site operations in the TFT-LCD industry, and proposes a strategy, in which cost and profit would have the same impact on the firm, to be realistically performed in the TFT-LCD industry.
