摘要

伴隨著近年來產業型態與結構的多變，電子產業的市場競爭日趨激烈，工廠的製造環境亦受到相當程度的影響。在市場日漸擴大的同時，企業為求持續成長，無不競相擴充產能以滿足市場現有以是潛在可能發生之需求，在目標市場不侷限於一地及成本、原料取得…等因素考量下，工廠生產型態亦由單一廠區逐漸演變為多廠區生產型態，生產規劃之複雜性相對提高。故在多廠區生產型態下，如何做好資源規劃，期使企業之營運及製造成本最小化，以獲致最大利潤乃成為重要課題。以本研究所探討之TFT-LCD個案公司為例，其模組作業廠區共有三座， 分別位於台灣及中國兩地，在每月月底或每年年底時產銷單位會依據業務單位所提供之銷售計劃分配各模組廠區未來所需生產數量，但分配各廠區生產數量進行時多以人為經驗為原則，無法使決策者得知何種分配結果對企業最為有利。為解決此問題，本研究將以系統化方法為思考點，考量研究範圍內各項生產與成本相關要素，以模組廠區總成本最小為目標建構線性規劃數學模型，使用LINGO軟體進行運算與求解，並將求解結果與個案公司實際分配資料代入目標函數運算所得成本做比較以驗證模式可行性。最後將進一步歸納模式驗證結果，並提出結論予個案公司做為實務運用之參考。

To get along with industrial structure is changeable and Electronic Industry market competition is getting furiously, the environment of factory is also affected through certain degree. When the present market is getting better, the enterprise will expand capacity to satisfied the needs of current and potential market for making progress continually. As the target market is not placed on one location and cost, material obtained must be considered carefully, the factory type has developed from one-site to multi-site, and the production planning is also getting complex. Therefore, how to implement resource planning to minimize the logistic and production cost and maximize the profit will be an important management topic. For example, the TFT-LCD industry case study of this research has three module operation plants, the location were either Taiwan or China. When sales department provide sales plan on the end of the month or year, the manager of module plants have to make decision to distribute the future production quantity for each module plant. But the decision maker is difficult to realize what distribution result is the best for company, because the decision also be made by personal experience. In order to solve the problem, this research will use systematized method to establish mathematic model, and solved by LINGO. To make sure the feasibility of this model, the results must be compared with the actual data of case study company be put in objective function. Finally, the comments will be summed up for the manager of module plants to make distribution decision.
