管理存貨是企業的一大挑戰，必須有效的管理存貨與降低成本來提升整體盈利性與競爭性，而經濟訂購量(Economic Order Quantity，EOQ)是被普遍所熟知，並且不斷發展與應用的一種存貨管理工具。近年來許多研究學者持續的探討且改進此模型使得模型更加貼合實際情況，它是利用數據的方式來更佳準確的掌控生產線與庫存，以此提供給企業做為管理存貨的有效工具。
本篇研究論文是在經濟訂購量模型下考慮了指數型態的需求函數，並且商品為延遲性退化產品；延遲退化商品與退化商品不同的地方在於商品退化的時間點不一樣，延遲退化商品會在某個時間點後才開始退化，並進而產生了損壞，因此庫存除了掌控完好的商品外還要扣除惡化且損壞的商品。而後還加入了商品的價格折扣因素，考慮綜上因素而進行成本與利潤分析。

The Economic Order Quantity (EOQ) is a commonly known, continuously developed and widely applied inventory management tool. In recent years, many researchers have continued to explore and improve this model to make it more realistic and hope it can provide the companies with an effective tool to manage the inventory and use data to control the production lines better.
This paper considers the demand as some exponential function and the commodities as the delayed deteriorating items in the Economic Ordering model. The difference between delayed deteriorating items and deteriorating items is that the time point of degradation is different. Delayed deteriorating items will start deterioration after a certain point of time and become damaged.
Therefore, in addition to the goods in the good condition, the inventory must also manage the deteriorated and damaged goods. Beside above, it also needs to take the price factor into account and then analyze the cost and profit.
