摘要

目前在逆向物流存貨系統的相關文獻上，大多數都是在探討僅包括單一回收再製商與單一零售商的一階存貨系統，但卻鮮少討論到考慮包含多零售商的二階回收產品存貨系統，且由於需求與供給往往難以進行預測，因此包含多零售商的二階存貨系統不確定性相當大。本研究參考了回收產品存貨系統的相關研究，探討當不同的製造與再製批量策略運用在包含多零售商的二階存貨系統的情況下，藉由模式的推導去求取最佳的新品訂購與回收再製批量，並考慮在加入回收產品丟棄的處理方法之情況下，對於整個存貨系統的總成本是否有影響。最後藉由模式的分析與驗證來檢定模式在各個情況之間的最小單位時間總成本是否存在顯著差異。結果顯示，除了在模式一不考慮回收產品丟棄機制、單一零售商之回收產品存貨模式中，在修復速率大於需求速率與修復速率等於需求速率的情況之間的最小單位時間總成本沒有顯著差異之外，有顯著差異存在於本模式其餘各個不同情況之間。

In the relevant literatures of reverse logistics inventory system, most of them only explored single-echelon inventory system including single remanufacturer and single retailer, but few discussed two-echelon inventory system including multi-retailers. And due to demand and supply are difficult to forecast, the uncertainty of two-echelon inventory system including multi-retailers is very considerable. This research refers to the related literatures about recovered inventory system to explore different inventory lot-size policies of new ordered and remanufactured products applying in two-echelon inventory system including multi-retailers, then considers whether aggregate disposal option of return products will affect the total cost of inventory system or not. Finally, to test whether the minimal unit total costs exist significant difference or not among different cases of proposed model. The result shows except model 1 that not considers disposal option and including single retailer, there’re no significant difference of minimal unit total costs among Case 1 that repair rate is greater than demand rate and Case 3 that repair rate is equal to demand rate, there’re significant differences among these cases.
