近年，全球化環保意識提升，進而對於‘回收’更加重視。建置一有效率的產品回收流程是有其必需性的。基於此原因，本研究提出一成本最小化模型用於多種類型廢棄產品之逆物流系統。此回收系統由四個處理階層所建構，分別為收集場、折解場、分離(淬取)場及最終處置點(包括次要市場及廢棄物處理場)。不同處理階層皆有其主要的特殊功能。本研究所提出之系統希望能將回收流程之總成本最小化，其成本包括了運輸成本、操作成本，廢棄物處理成本以及重新利用再生物料之利潤。此回收系統為一混整數規劃模式，本研究利用AMPL(一線性規劃處理軟體)求解最佳回收物流處理模式。

Recently, the growth of environmental concerns has given increasing attention to the concept of ‘recycle’. An efficient product recycling process is required. For this reason, this research establishes a minimum cost recycling network configuration model for multiple products. This general model is based on the logistic transportation model, while being applied in a reverse fashion. The recycling system network is constructed with four process layers, including a: collection site, disassembly site, extraction site, and termination site (for reuse, resell, or disposal). Each process layer (or site) has a unique and distinct function. The proposed model attempts to minimize the total cost, which consists of transportation cost, operating cost, and final disposal cost, as well as the sale revenue of reclaimed materials. The mixed integer programming model is solved by AMPL. The optimal material flow will be shown.
