摘要

由於傳統供應鏈管理多僅探討正向物流營運相關議題，對於產品清理、回收等諸多議題較少探討，再加上近年來環保意識的逐漸抬頭，使得逆向物流逐漸成為研究重心。只往關於逆物流中再製造議題的研究，多在製造商需擔負再製造的責任的前提下，進行新製與再製決策的研究，對於政府環保費率機制如何影響製造商決策之研究則較為缺乏。因此本研究希望在納入費率制資源回收機制的前提下，檢視相關參數對於製造商新製與再製決策之影響，並引伸其管理意涵。
首先本研究將參考學者對於再製造流程研究與相關文獻，結合台灣現行之資源回收制度，建構以費率制為主的資源回收體系情境，並以製造商成本極小化觀點，設計隨機線性規劃多期模型，並設計隨機情境，用以分析製造商在面對產品需求、可再製物料回收及其市場價格等變異、及向產品收取資源回收處理費率的訂定公式等諸多因素下，其總成本、新製量和再製量的變動。
由分析結果得到製造商所面對的產品需求量變異、可再製物料回收量變異及費率結構的訂定，皆會對製造商總成本帶來衝擊，但可再製物料價格的變異程度卻沒有顯著影響，其中費率結構中用以調節製造商各期費率的調整因子尤其有重要地位，資源回收管理基金在訂定費率結構時，需將會影響製造商各期費率的因子納入考量，以確保該費率結構可同時保障逆向物流中相關業者和製造商的合理利潤。

As environment sustainability became an issue of growing interest, reverse logistics has attracted more researchers to work on this field. Unfortunately, the researchers in the past more focused on making manufacturing and remanufacturing decisions assuming that manufacturer has to take the fully responsibility of remanufacturing without considering the government’s environmental protection mechanism. Thus, in this research, we bring the issue of environment protection fee and subsidy mechanism into consideration, and examine how the related parameters affect firm’s manufacturing and remanufacturing decisions.

At first, a multi-period stochastic linear programming model is constructed on past researches of remanufacturing process and current fee and subsidy practice in Taiwan. Next, experimental design associated with scenario planning is used to analyze how total manufacturing cost, manufacturing quantity and remanufacturing quantity are affected when manufacturer faces different variations from product demand, availability of remanufacturable materials, the spot market price of remanufacturable materials, and fee and subsidy structure.

From the results of analysis, we find that product demand, availability of remanufacturable materials, and fee and subsidy structure have the greatest impact on total manufacturing cost, while the spot market price of remanufacturable materials has less impact. We could also observe that the parameter in fee and subsidy structure plays an important role in determining the fee expense for each period. Recycle Management Fund must take all factors into consideration so as to make sure that the fee and subsidy structure could assure the reasonable benefit of recycle firms and manufacturer.
