摘要

國際社會期待企業在環境保護議題上扮演更積極的角色，廠商必須負起收集、回收並妥善處理產品的責任，因此封閉迴圈供應鏈(Closed-loop supply chain)近幾年來一直是熱門的研究領域，除了如何將產品由生產者交送到消費者手中外，它還強調產品的退回收，針對不同的回收內容都有一個相對應的逆向供應鏈 (reverse supply chain)架構。此外許多正向供應鏈（Forward Supply Chain）的研究中都強調產品設計在供應鏈管理中的重要性，因此本研究特別將類似的觀念應用在封閉迴圈供應鏈上，研究產品設計參數，尤其是共用零組件的使用對封閉迴圈供應鏈的影響。
本研究比較兩種主要的封閉迴圈供應鏈架構，一是平行 (Parallel) 架構，在此種結構中有兩條不同的產線，一條專為組裝產品，另一條專為拆解產品，兩條產線互相獨立。另外一個則是混合 (Mix) 架構，與平行架構最大的差異在於組裝與拆解兩種工作都在同一條生產線進行，混合結構的處理機台不但可以執行組裝的任務也可以執行拆解的任務。本研究探討是否使用共用零組件、共用零組件擺放位置、與延遲差異化程度對供應鏈正向流程時間(Cycle Time)的平均與變異有何影響。
我們根據共用元件及封閉迴圈供應鏈的特性，提出許多管理洞見的假說，幫助管理者瞭解如何在封閉迴圈供應鍊中妥善使用共用元件。

Due to the rising awareness of environmental protection and stringent regulations, companies are expected to take more responsibility to protect the environment including collecting and recycling their product. Hence, closed-loop supply chain which not only dealing with the distribution of new products but also collection and recycle of the used products becomes a very important research topic. In addition, many literatures in forward supply chain point out the importance of product design. In this research, we follow the same concept and apply it to closed-loop supply chain, especially how component commonality impact the closed-loop supply chain.
We consider two closed-loop supply chain structures, Parallel and Mix. In the Parallel structure, the assembly and disassembly lines are separated while in Mix structure they are performed by the same production line. We study how the usage and the location of common component as well as the degree of delayed differentiation enabled by common component impact the cycle time of forward supply chain under these two structures.
We base on the character of component commonality and closed-loop supply chain to address some hypotheses of managerial insights to help managers design their product better using common component in the closed-loop supply chain
