摘要

學者Billington (2003)在最近的研究中提出新的概念：企業可藉由投資活動(如增添或改善儲存設備)縮減存貨之單位持有成本，藉此達到降低存貨總成本的目的。然而，他的研究是以傳統經濟訂購量(EOQ)模式為基礎，考慮單一企業的存貨問題。隨著供應鏈管理理念的出現，企業管理者在發展有效的存貨管理模式時，應考慮整合供需體系的供應鏈成員，共同制定存貨策略，以便降低成本並提升企業之競爭優勢。本研究旨在探討供應鏈體系下的企業如何透過增加投資支出，以期使存貨之單位持有成本降低，進而達到降低整合存貨系統總成本的目標。
本論文以Yang and Wee (2002)所提出之單一買方、單一賣方整合存貨模式為基礎，分別考慮買方與賣方之單位持有成本可藉由投資方式而加以縮減，據此建構包含投資策略的整合存貨決策模式。文中先以計量方法進行模式的分析，而後發展求解演算法，並以數值範例說明此一投資策略對整合存貨系統的影響，探討成本縮減效益與買賣雙方如何協商補償以達到雙贏的目標。

From the work of Billington (2003), we know that enterprises could try to reduce the cost of holding items by extra capital expenditures, and then achieve the goal of reducing total costs associated with inventory system. However, his study is based on the classical economic order quantity (EOQ) model, which is suitable for the single enterprise. With the development of Supply Chain Management (SCM), integrated inventory systems that determine the inventory policy for the members of supply chain jointly have received a lot of attentions. The aim of this study is to examine the effects of investing in holding cost reduction on one of the existing integrated inventory systems.
In this study, the single-vendor single-buyer integrated inventory system contributed by Yang and Wee (2002) is extended to include investing options of holding cost reduction. Two models are proposed and analyzed. The first one considers that the buyer’s per unit holding cost is controllable, the second one considers the same situation for the vendor. The objective is to simultaneously optimize the order quantity, number of deliveries and capital expense on reducing holding cost. Through the mathematical analysis, an algorithm of finding the optimal solution is developed. Then, numerical examples are provided to illustrate the solution procedure and the results of proposed models. Also, sensitivity analyses are performed to examine the effects of problem parameters on the optimal solutions.
