摘要

隨著市場競爭與產品多元性的需求，流行性商品的生命週期日益縮短。加上具有時效性與難以估計市場需求等因素，製造商與零售商往往面臨在生命週期期末存貨過多或期初缺貨的問題，造成買賣雙方的損失。此外，在競爭的全球化經濟發展中，產業為了拓展市場佔有率已逐漸重視供應鏈整合，並取代敵對的上下游企業夥伴關係，以求快速回應市場需求並增加供應鏈整體的利潤。
故流行性商品、產品生命週期的特性、供應鏈整合的觀念及缺貨、退貨與回收的存貨模式已逐漸受到重視，但卻少有人將它們做整合性地討論。因此本研究考慮一個製造商與一個零售商的供應鏈，藉由製造商提供的退貨與回收補償價與零售商的多次折扣策略，建構出風險共擔的流行性短生命週期產品的退貨與回收模式。減少生命週期中，流行性商品的不確定性因素，並加入考量缺貨狀況與退貨後商品轉賣的機制，達到供應鏈整體利益最大化的多贏局面。
在此狀況下，本研究以總期望利潤最大化為目標，探討製造商及零售商於整合與未整合的情況。並利用Maple 8.0 與Excel為運算工具，推導出零售商最佳訂購量、最適期初定價及期望利潤間的差異狀況，最後運用數值範例與敏感度分析驗證模式的合理性。

Due to the globally competitive environment and the diversified product demand, the product life cycle (PLC) of fashion goods is getting shorter and shorter. Because of the life time-limit and the difficulty to estimate the market demand, the manufacturer and the retailer will have excess or shortage of stocks at the end or start of the PLC. Furthermore, in order to raise the market share, it is critical for companies to collaborate with other players in the supply chain. The adversarial relationship must be replaced by a cordial relationship so as to respond quickly to demand and increase supply chain profits.
Inventory model for fashion goods, PLC, supply chain with coordination, backorders, return and reuse policy have been developed in many papers, but very few of the researches incorporate these effects simultaneously. In this research, we consider a supply chain problem with a manufacturer and a retailer. The manufacturer compensates the retailer with return and reuse goods, while the retailer encourages large orders by providing multiple price discounts to the customers. We also consider the uncertainty of backorders and resale value of the fashion goods.
Finally, we compare the expected optimal profit with and without coordination. Maple 8 and Excel software are used to implement the symbolic and the numerical analysis. A numerical example and sensitivity analysis are given to illustrate the theory.
