摘要

隨著新世代科技日新月異和產品的高標準化以及顧客需求多變，導致產品生命週期縮短，企業間的關係密不可分，所以一旦供應鏈出現斷鏈問題，就必須盡快地在第一時間內解決，否則將影響整個企業組織，在本研究當中，將探討發生斷鏈危機後的最佳訂購量Q*及總成本Tc，故本研究的目的為了使受到斷鏈影響的供應鏈能盡快恢復正常運作，且讓利潤最大化，研究當中會求出在斷鏈機制下的最佳訂購量Q*及總成本Tc，並探討斷鏈程度與Q*及Tc有何種關聯。
研究當中會假設需求D是固定的情況下，且斷鏈程度由0.01~0.09的模擬下，在單一資源理論及雙重資源理論下，利用excel進行模擬，發現斷鏈程度的高低與Q*及Tc是有關聯的，斷鏈程度越高，Q*的數量就會越低。
對單一資源理論及雙重資源理論在不同得斷鏈程度下進行模擬後，得知雙重資源理論優於單一資源理論的地方在於，多了一家供應商，在補給貨品方面，不幸發生斷鏈時，有較充足的資源，以利潤為優先考量的情況下，求出最佳訂購量Q*及Tc後，便能從兩家供應商中進行取捨。

In the new era, the ever-changing technology and the high standardization of products as well as the customer needs diversification, the product life cycle has been shortened. Also the relationship between supply chain among enterprises has become inseparable. Therefore, once the supply chain has a disruption problem, it must be solved within the first time. Otherwise, the organization of enterprise will be affected. In this study, we will discuss the optimal order quantity Q * and the total cost Tc after a disruption risks. Therefore, the purpose of this case study is to make the supply chain return to the normal when the disruption risks is come, as well as to maximize profits. This study will find out that the best ordering quantity Q * and total cost Tc under the disruption mechanism and explore the relationship between the degree of disruption and Q * and Tc.
Under the assumption that demand D is constant and the chain breaking degree is from 0.01 to 0.09, under the single resource theory and dual resource theory, by using excel to simulate that find out the relationship between the degree of disruption and Q * and Tc is related, the higher degree of disruption, the lower number of Q *.
After simulating under different degrees of broken chain by single resource theory and dual resource theory, figure out that dual resource theory is superior to single resource theory. because when the chain is unfortunate, with sufficient resources, in the supply of goods, with profit as a priority, we can choose the best suppliers Q * and Tc, when there is more than one supplier.
