近年來,由於環保議題受到產業及學術界高度重視,許多國家開始訂定嚴苛法規來規範企業之責任,企業面臨這些外在經營環境的改變也紛紛開始尋找對應策略。因此本研究以資源回收再利用並結合循環經濟為概念,進行探討賣方除了利用購置的新品來滿足買方的需求外,也可搭配利用回收使用過之產品作為再製生產的原料來源,經過再製生產後以新品方式售出來滿足買方的需求。藉此不僅可降低生產成本,亦能降低碳排放產生,達到循環經濟之回收再利用成效。故本研究結合碳稅及產品回收再製兩個重要課題,進行最佳訂購與再製造生產策略訂定之研究。並提出演算法進行求解,進行數值範例說明,針對重要參數進行敏感度分析。,研究中將提出可求得最佳品質水準、最佳再製次數、批量以及最佳新品訂購次數與批量。最後本研究撰寫簡易介面系統,提供使用者操作後,可立即得到最佳決策及方向,藉以提供參考。
Owing to the increasing environmental awareness, firms are pursuing means in compliance with emerging related regulations. This study aims at resource recycling regarding to circular economy between sellers and buyers in case of deciding new products and recycled products as a part of raw material for remanufacturing. The decision of recycled products may reduce production costs and carbon emissions, and achieve the goal of recycling economy as well. Regarding to the factors of carbon taxation and product recycling, two optimal ordering and remanufacturing production strategies with algorithms for solving the problem are formulated and numerical examples are also given followed by sensitivity analysis for critical parameters. Conveniently, a simple interface system is designed to real-time make decisions for users.
