隨著產品生命週期的縮短，大量的廢棄物對人類生存環境開始造成威脅，各國開始正視廢棄物管理的議題，紛紛立法來規範廢棄物的回收管理。企業為了成本、企業形象、法律規定等因素開始將逆物流(reverse logistic)納入其營運規劃。但在逆物流資訊難以取得以及具備大量的不確定因素下，許多企業選擇將逆物流外包給專業的逆物流業者，以專注在其核心能力之上。
在單純的外包模式下，企業時常面臨回收商無法穩定供給再生物料之問題，若再生物料使用比率無法達到法規要求，則需繳納高額的回收規費，部分企業甚至以新產品分解為新再生物料來補足再生物料短缺以迴避高額的回收規費；回收商則會面臨企業再生物料需求數量不穩定或是數量不足，單次運輸成本大幅提高，使其表現出只願回收退回商品取得回收補貼，但不分解販售再生物料，而是堆放退回商品於集散處的傾向。
本研究提出一綜合回收商及製造商之緊密營運模式，考量連續時期、利潤共享的條件下，建立一數量決策模型，以整體利潤最大化為目標，探討不穩定因素下之每期穩健再生物料分配決策。因應大環境之不穩定因素，將以建構情境為基礎之穩健最佳化模式求得穩健解。 / In recent year, enterprises consider reverse logistic in their processing because of cost, corporate image and government policy. But there are lots of uncertainty factors in the reverse logistic, in order to focus on enterprise’s professional skills, more and more enterprises outsource their reverse logistics.
Both enterprise and professional reverse logistic processor have to spend more costs to keep their cooperation in recent outsourcing model. Thus, this thesis builds a model which combine enterprise's business model and professional reverse logistic processor's business model. In this model, assumes that profit should be share between both of them, and apply Robust optimization methods to solve uncertainty factors in reverse logistic. The thesis finds out the best distribution ratio of regeneration materials in each period.
