摘要

中文摘要
過多的存貨會將企業暴露在高風險的環境底下且會影響管理的績效，存貨成本的控制就變得很重要，過往學者針對存貨成本的控制發展出一套成本模型來找出經濟生產量 (Economic Production Quantity; EPQ)。
最早在Hartley (1976) 提出兩個倉庫的庫存模型，解決倉庫有限值的問題。許多零售商的信用交易模式為顧客都能擁有固定一段時間，最早以 Teng and Goyal (2007) 的二階信用交易政策提出這項論點，這與以往存貨模型較常引用的Huang (2003) 的二階信用交易概念不同，因此根據以上兩點，本研究將發展出另一套成本模型來綜合探討在二階信用交易與有限倉儲條件下零售商考慮不同還款期限之EPQ。
研究過程首先找出總相關成本模型架構，探討成本模型的連續性，並將成本函數進行一階微分處理，探討遞增或遞減，再探討成本函數斜率的連續性，進行二階微分處理，探討極值，加入引理證明成本函數有其最小值，探討所有情況的最小值以找出EPQ，並進行敏感度分析得出相對影響幅度較大的關鍵變數，最後提出結論及建議，在政策建議上將以影響幅度較大的變數優先處理之。

Abstract
Inventory control is important for business. Previous scholars develop a cost model to identify the Economic Production Quantity.
Hartley (1976) proposed the inventory model of two warehouses first. It solved problems of finite value of the warehouse. Retailer’s trading model of credit let customer have a fixed period of time to pay money. It is proposed by Teng and Goyal (2007). It is different with trading model of two levels trade credit that is proposed by Huang (2003). Based on the above two points. This study will develop a new cost model to discuss.
