第三方回收企业对闭环供应链的回收与定价策略研究
Research on Recycling and Pricing Strategies of Closed-Loop Supply Chain by Third-Party Recycling Enterprises
文章以废旧汽车回收为例, 研究第三方回收企业对闭环供应链利润的影响. 为了将加入第三方回收企业的闭环供应链和传统无回收的正向供应链进行比较, 首先, 建立了以下四种模型: 传统决策模型、加入第三方回收企业的分散决策模型、集中决策模型和收益共享契约的决策模型. 其次, 基于无偿情形下的回收量和有效回收固定成本系数对四种决策模型求解比较, 得 出如下结论: 供应链和制造商的利润与无偿情形下的回收量呈正相关, 与有效回 收固定成本系数呈负相关; 对制造商和整个供应链来说, 契约协调后供应链的利 润最大, 分散决策次之, 传统决策最小; 对零售商来说, 契约协调的利润大于传 统模式和分散决策时的利润. 再次, 数值验证了结论的正确性. 最后, 给出国家应该给予第三方技术支持和相应的补贴政策, 大力宣传资源重复利用的环保意识的建议.
This article uses waste car recycling as an example to study the impact of third-party recycling companies on closed-loop supply chain profits. In order to compare the closed-loop supply chain joining third-party recycling companies with the traditional non-recycling forward supply chain, first, the following four models were established: Traditional decision models, decentralized decision models joining third-party recycling companies, centralized decision models, and Decision model of revenue sharing contract. Secondly, the four decision models are solved and compared based on the recovery amount under the free situation and the effective recovery fixed cost coefficient, and the following conclusions are drawn: The profit of the supply chain and the manufacturer is positively related to the recovery amount under the free situation, and is effective to recover the fixed cost. The coefficient is negatively correlated; for manufacturers and the entire supply chain, the supply chain profits are the largest after contract coordination, followed by decentralized decision-making, and the traditional decision-making is the smallest; for retailers, the contract-coordinated profits are greater than traditional models and decentralized decision-making. Profit. Again, the numerical results verify the correctness of the conclusion. Finally, it gives suggestions that the country should give third-party technical support and corresponding subsidy policies, and vigorously promote environmental protection awareness of resource reuse.
