碩士 === 國立交通大學 === 管理科學研究所 === 84 === The classical Economic Order Quantity model assumes the parameters of the model to be constant. But in the real world situations, many parameters such as the demand rate, the purchasing price, and other cost elements may vary from time to time. In this study, we develop two ordering policies to control the inventory system where one or all of the parameters will change at some time in the future.　　When only the change of purchasing price is expected, our numerical examples show that Policy 2 is the best ordering policy. When charges of more than one parameter are expected, Policy 1 becomes the best choice in several cases. The difference of average total inventory cost between the two policies is, however, very insignificant and can be neglected. Therefore, we suggest that Policy 2 should be implemented in the real world application and can provide the inventory system with satisfactory results.
