考量運輸折扣下針對單品項配銷系統及存貨配置問題之連續性模型 摘 要 在物流系統中，運輸成本佔了總成本三分之ㄧ至三分之二，也因此若要確實地降低物流活動成本，著手於降低運輸成本會是一個好的選擇。在現實世界中設計一個有效率的配銷系統往往是個難題。運用傳統的離散性數學模型處理配銷系統問題是學術上常見的手法，然而為追求真實性高的離散模型，所需要的資料量及計算步驟是相當龐大的。使用連續性模型不需要複雜的資料及大量的運算，且同樣能經由分析結果來提供決策者關於系統行為的重要訊息。本研究將運用連續性模型處理整合性的單品項配銷系統及存貨問題，且在模型中考量到運輸數量折扣對於整個系統之影響。研究者將會分析模型所得之結果並提供有意義的管理觀點作為結論。 A continuous model for single-item distribution system and inventory allocation problem under transportation cost discounts ABSTRACT Transportation creates the value of place in distribution; however the delivery of goods will not take place if an efficient transportation does not exist. Transportation cost accounts for 1/3 to 2/3 of logistics cost, and therefore make it a good candidate for logistics cost reduction. Designing an efficient distribution system is then an important task in practice. Traditional discrete models are popular in academics while dealing with a distribution system, but data and computational requirements increase tremendously as models become more realistic. Without complex data and computational processes, using continuous approximation technique to model the logistic system and analysis the result can provide the decision-maker useful information about system behavior. This research utilized a continuous model to represent an integrated facility location and inventory allocation problem for a single-item distribution system, and considering the effect of transportation quantity discounts in the model. The researcher will analysis the result of the model and provides meaningful insights as a conclusion.
