摘要: | 為刺激廢棄產品的回收處理作業循環,現今許多國政府已提供補助予逆向供應鏈上的角色。本研究討論政府補助對於四階層分權式逆向供應鏈中電子廢棄品回收作業的影響。本研究建構出具電子廢棄產品來源、回收作業商、處理作業商與需求市場之四階層分權式逆向供應鏈模型,假變分不等式之均衡條件整合四個階層角色各自的最佳化模型,以修正投影法求得均衡解。本研究將四階層分權式逆向供應鏈模型套用至真實案例,比較不同的政府補助方案。整體而言,政府僅提供處理作業商補助的方案能使整體逆向分權式供應鏈之電子廢棄品回收處理作業績效達至最高。 Government subsidies to reverse supply chains can play important roles in driving or curtailing the flows of recycled items. We examine the impacts of exogenous subsidies on recycled material flows in a decentralized reverse supply chain where each participant acts according to its own interests. We outline a multitiered model of the supply network from sources of scrap electronics, collectors, processors and demand markets. The individual behavior of each player is governed by participants’ optimality conditions, which are mathematically transformed into a variational inequality formulation. The modified projection method is utilized for solving the equilibrium quantities and prices of each participant. We investigate the impact of alternate schemes of government subsidies on decisions of the equilibrium quantities, prices and the total amount collected. For the case studied in this study, the best tier selection between collectors and processors for government subsidies in terms of the overall recycling performance is located in processors in laptop computer reverse supply chains. |
