摘 要
隨著全球化的程度日深,使得企業在面臨組織資源有限與必需積極趨利避險,以擴大產業競爭優勢的同時,如何在有限期程內正視存貨的控制,以減少倉儲成本不當積累,並尋求最大的成本效益為依歸,應是重要的課題。
傳統EOQ存貨模式,因著簡明易懂、便於運用,並得以訂購成本及存貨持有成本之最低累績總和,決定最佳訂購量及次數,儼然引為當代論述之要。然亦因其限制條件眾多,致時生結果與實情相悖情事。如傳統EOQ存貨模式,假設通貨膨脹處於極其穩定狀態,即未將折現的因素考量在列,顯與現況不符。因此嗣後由Trippi 和Lewin等學者,針對真實現況輔以補強因素後,陸續運用折現等方法,提出較合理的模式加以探討,以充分描述實情與現況相結合,即此立意。
本研究據此要義,依據Kim、Philippators及Chung等三位學者,藉由現金流量之動態資訊,對於整批銷售、有限均勻生產存貨系統,所提供之評鑑存貨的投資方法為研究方向。研究提出運用模擬退火法求取存貨模式之最佳週期的研究所得,並分析其優越性。
  同時並研究建立,另一以有限時距為分析縱軸的模式,期藉有限與無限時距之比較,提出本研究論述見解,並究其時距差異分析,俾利以不同面相呈現事實原貌,以增益企業組織運作時參據。
關鍵詞:存貨、最佳週期、淨現值、模擬退火法

ABSTRACT
Complying with the depth of globalization, enterprises in organizationally bounded resources, positively profit-approaching, and risk-avoiding positions to amplify sustainable competitive advantage, should be focus on inventory control in a limited period to decrease inappropriate accumulation on inventory carrying cost and the orientation of procurement of maximum cost benefit as a vital lesson.
The traditional EOQ inventory model is often used as a main method to solve the above problem’s proposed . Due to its easiness and convenience. With many bounded conditions, however, it sometimes results in contradiction between expected and actual outcome. The traditional EOQ inventory model assumes inflation is in a very stable status without taking discount into account as a factor, which obviously effect the real situation. Therefore, the specialists, like Trippi and Lewin , announced several reasonable models adding reinforcement factor in real situation in discussing so that the real situation can be fully described.
This research adopts the investment approach of evaluating inventory in batch sales and finite uniform production rate inventory system by the dynamic information of cash flow published by Kim, Philippators and Chung. We use Simulated Annealing Algorithm to find the optimal cycle time of inventory model and analyzes the superiority of the approach.
This paper establishes a model with finite time horizon as analytical axis and provides viewpoints by comparing finite time horizon and infinite time horizon. According to analysis of time horizontal gaps, this research actually presents original its with different dimensions and makes a reference for enterprises to improve the operations.
Keywords:Inventory, The Optimal Cycle Time, Net Present Value, Simulated Annealing Algorithm
