dc.description.abstract | 由於所處環境不同,或者存貨類別有所差異,導致企業間可能產生不 同的存貨政策。過去經濟訂購量(EOQ) 模式均假設其影響成本的參數為固 定值,但是在現實生活中,任何影響成本之參數均可能隨時改變,或者是 可預知未來這些參數即將改變。例如,已預知原物料價格即將上漲則導致 目前需求量之變動;也可能因為未來倉儲租金及費用的上漲導致持有成本 上揚而改變目前的訂購量等。因此本研究假設已知未來某一時點影響存貨 成本之參數即將改變,這些變動的參數包括需求率、訂購成本、持有成本 以及採購成本,以探討並選擇最適之存貨政策,並發展出兩個訂購策略( 甲、乙兩案)。另外,本研究的結果並與 Lev & Weiss [18] 之模式比較 ,進而探討是否存在著另一種較佳的存貨模式。 本研究結果如下: 1.在假設只有採購價格變動的條件下,由實證得知乙案乃最佳訂購策略 ,但甲案的結果大都優於 Lev & Weiss 中之另一訂購策略。 2.當允 許所有參數改變時,經由實證得知,甲案訂購策略在某些參數條件下較優 。但是,甲乙兩種存貨政策之單位時間成本差並未超過 0.6%。因此本研 究建議,在實務運用上,因乙案可提供令人滿意之結果,決策者只須考慮 採用乙案即可。 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. | zh_TW |
