基于第三方差别定价回收的闭环供应链协调问题

Closed-loop Supply Chain Coordination Problem Based on Third-party Differentially Priced Recycling

根据第三方回收的废旧品是否具有可再造性,将废旧品分为可再造废旧品和不可再造废旧品两类,考虑到政府对制造商的激励作用,分别建立了闭环供应链的集中决策利润模型和分散决策利润模型,并得到了集中决策下闭环供应链系统的效率优于分散决策下效率的结论。最后用收益-费用分享契约对分散决策下的闭环供应链进行了协调,并用算例证明了模型的有效性。

In this paper, depending on whether third party recycled waste products are recyclable, we divided them into two categories,namely recyclable waste products and non-recyclable waste products. Next, considering the effect of government incentive on manufacturers,we set up the closed-loop supply chain profit model respectively under centralized and distributed decision-making, and concluded that the efficiency of the closed-loop supply chain system under centralized decision-making is better than that under decentralized decisionmaking. Finally, we coordinated the closed-loop supply chain under distributed decision-making with the benefit-cost sharing contract, and proved the effectiveness of the model through a numerical example.
