摘要


全球化的市場,現今強調從供應商、製造商、配銷商到最終顧客的資訊和物料管理供與需的商業行為中,賣方提供他的貨品給買方時,尋求最小成本而達到企業存貨策略,預測存貨的目的在於控制存貨成本的適當性,追求利潤極大化則是企業的最終目標,也是永續經營的使命。當存貨管理未能妥善應用日後將造成需求剩餘或短缺的問題,為防止缺貨造成損失或管理不當等因素所造成的影響,存貨滿足率又能維持在一定水準的前提下,進而研究最佳的存貨最佳模式。 本論文以Soni & Shah(2008)提出需求率非固定常數且隨存貨變動。內文中嘗試建立需求為非固定常數且隨存貨變動的模式為研究方向,以單位時間現值觀點分析求解最佳獲利模式。用不同的數理推導方式,討論一個中間商所持有的商品是具有耗損特性,在需求與存貨水準相依下,利用分析的方法來證明單位時間最小成本函數的存在,並求得最佳訂購週期時間與訂購批量。另針對以探討影響利潤的結果亦考慮購進商品之後耗損產生會影響銷售率及獲利能力,因文中強調其利潤之最佳化之充分條件為需求函數作為數學模式之架構,依本研究假設在週期時間的總銷售利潤之淨現值=(週期時間之收入現值-週期時間之總成本現值),利用分析方程式來驗證最佳利潤模式是否為真。經由分析證明利潤函數有最的大利潤存在。

The globalized market, in now a days, emphasizes that the ultimate goal and sustainable mission of the enterprise are to seek the maximum profit by the business model consisted of suppliers, manufacturers, distributors and inventory management on end- customer side; in this model, the sellers always seek the minimum cost by properly controlling the inventory with a inventory management strategy and forecasting of inventory. Failure to apply inventory management properly will result in surplus or shortage of demand and the impact of loss or mismanagement. In order to prevent the shortage of inventory and mismanagement and maintain the certain level of inventory to satisfy the fill rate, this study will focus on the optimum methodology of inventory management. In this paper, Soni & Shah (2008) propose a non-fixed constant demand rate and with the inventory change. This paper tries to establish a pattern in the non-fixed constant demand and with the inventory change direction for research in time to solve the present value analysis unit view the best revenue model. With a different way of mathematical derivation, held to discuss a commodity broker is a loss characteristics dependent on the demand and inventory levels, the use of methods analyze the smallest unit of time to prove the existence of the cost function, and get the optimal order cycle time and order quantities. After the result against another in order to explore the impact profits also considering the purchase of goods produced will affect the sales rate of depletion and profitability, because paper stressed that the full optimization of the conditions for the needs of its profits as a function of mathematical models of architecture, under this hypothesis in net present value of total sales profit of cycle time = (current income of the cycle time - the total cost of the present value of the cycle time), use the analysis equation to verify the best profit model is true. Numerical analysis through profit function by the second differential proved less than zero, confirmed that the maximum profit is there.
