摘要


近年來環保綠色意識的抬頭,使得原先變化激烈的社會環境不能單單只以創造為主要的衡量指標,必須考慮產品的屬性是否能符合環境法規的規定,且在產品壽命的最終階段是否能有效的處置。同時,企業決策的方針由傳統的局部最佳化,轉而將上下供應商整合為一追求整體最佳化的完整供應鏈體系。因此在考慮這樣的雙重課題之下,藉由整合上述議題的方式將可提升企業的競爭能力,以達到雙贏的局面優勢。 本論文研究的對象主要是針對單一週期存貨、無銷售季節限制的模組化商品為主。研究的目的是將傳統報童模式加以擴充,在模組化商品具隨機退貨的情況下,加入商品在出廠前不具品質檢驗的條件、退貨商品轉賣和期末退貨政策的考量下,探討單期決策模式對於期望總利潤在考慮單一零售商或是考慮零售商和製造商整合的情況兩種模式下之最佳訂購量。本研究所建立之數學模式,以存貨理論和相關機率統計為基礎,追求問題利潤最大化,並以數學軟體Maple輔助求取最佳訂購量,並透過數值範例和敏感度分析來了解影響模式的重要參數。由本研究的模式建構、數值範例與敏感度分析中,將可驗證出在通路整合情況下的利潤會比考慮單一零售商來的更高,故可得知,整個供應體系為考量的情況將可獲得更高的利潤,達到通路整合的期望效益。

In recent years, emphasis on green issue is increasingly. Enterprises must consider products life cycle, and include product characteristics in their innovation and environmental laws. Moreover, in order to maximum the profit, collaboration decision strategy must be considered. In this research, we present a single-period inventory of modular products without considering the sale season limitation. Our study extends the basic newsboy problem with modular products to consider resale, defective items and stochastic returns. The optimum quantity is derived for a case when the expected profit with or without collaboration situation is considered. The research methodology and model development are based on the inventory theory, the probability and statistic theory. Software is used to obtain the optimum order quantity which maximizes the total profit. Numerical examples and sensitivity analysis are carried out to illustrate the influence of certain parameters. From the numerical examples and sensitivity analysis, it is shown that the optimal order quantity increases the channel profit when collaboration is implemented in the systems.
