碩士 === 東吳大學 === 會計學系 === 97 === In the past years, since the consciousness of inventory management that the enterprise concerns was formed step by step, the researchers focused on the issues of inventory management. Although the Economic Order Quantity Model make a great contribution in inventory management, the model still exist many unrealistic assumptions. Hartely(1976) was the first researcher to assume that when EOQ exceeds the capacity of owned-warehouse, the enterprise can rent additional space to store the quantity and achieve a lower total system cost. In addition, currently the products produced by enterprise are almost consumables, so they usually will come up the phenomenon of “inventory decaying” showing that custody of inventory is an important issue. However, the services provided by space supplier actually didn’t differ from the behavior which is selling the product done by general enterprise while the enterprise has decided to rent a warehouse from outside. The better the level of quality of products is, the higher the price is. Similarly, the superior the storage environment is, the higher is the rent. In other words, the rent of the rented warehouse depends on whether the storage environment is good or not. Therefore, this paper considers the deterioration of inventory during holding period, establishes an EOQ model simultaneous considering deteriorating items and ordering quantity, and finds an optimum solution. Finally, this paper will conduct sensitivity analysis and make a summary about how optimum solution varies with each parameter which changes at a ratio.
