摘要

在當前激烈的市場競爭環境中，靈活地運用各種存貨管理機制，方能獲得更大的競爭優勢，從而謀取企業生存競爭的必要條件。因此，買賣雙方如何在合作下訂定適當的存貨策略使得存貨總成本最佳化，將成為企業競爭優勢的關鍵所在。
在實務上，供應商通常會提出誘因來鼓勵觸控面板廠商增加訂購量，最常見的方式為現金折扣與延遲付款的信用交易，本研究亦是考量允許延遲付款及原物料儲存成本下之最佳補充存貨策略。
此外，Chung & Huang(2003)僅考量允許延遲付款下來建立最佳補充存貨策略，實際上，在沒有考量原物料儲存成本的情況下，觸控面板廠商則會明顯低估企業庫存成本對最小單位時間平均成本和最佳訂購週期的影響。隨著原物料單位庫存成本的增加，最佳訂購週期的長度會減小，而最小單位時間平均成本會增加。基於此，本研究以Chung & Huang(2003)的模型為基礎，將原物料儲存成本導入模型中加以比較討論。最後，綜合上述條件，本研究建立不同狀況下的存貨模式，並針對模式的建構與求解過程，最終獲得觸控面板廠商的最佳訂購策略，使得存貨模型更能符合實際現況。

Due to the increasing competition in the market, using flexibly various inventory management mechanisms, then can promote the competition ability of the enterprise, and achieve the essential conditions of struggle for existence of enterprises now. So the buyer and the vendor subscribe under the cooperation decides the suitable goods in stock strategy to let the goods in stock total cost optimization, for enterprise competitive advantage key.
In practice, suppliers would usually offer incentives to touch-panel enterprises in order to prompt orders volume. Among the most prevalent methods used is the credit transaction, with two forms of case discount and postpone payment. This research is intended for the optimum inventory strategies for enterprises in terms of postpone of payment and inventory cost of raw materials.
Moreover, Chung and Huang only consider the permissible delay in payment to build the optimal cycle time for EPQ inventory model. In fact, Without considering the inventory cost of raw materials, the touch-panel manufacturers will underestimate the effects of the inventory cost on the minimum cost and the optimal cycle time. With the increase of the unit inventory cost of raw materials, the length of the optimal cycle time will be decreased, but the unit minimum cost will be increased. Base on this, the research wound take Chung and Huang’s model as foundation, in which the inventory cost of raw materials is considered as one of the factor to be discussed. In conclusion, with summery of the conditions mentioned above, this research would establish different inventory models. Through analysis and differentiation to the structures of those models, the principle could be worked out to shape the best purchasing strategies that could conform to the actual inventory status.
