考虑政府多政策和第三方回收的闭环供应链协调机制研究

A Research on the Coordination Mechanism of Closed-loop Supply Chain Based on Government Multi-policy and Third-party Recycling Mode

分析政府多政策情形下第三方回收模式闭环供应链的协调问题。考虑政府多政策以及零售商主导,建立3种不同情形的供应链模型,并比较分析各情形下的供应链最优定价决策和利润。研究表明,政府多政策能够有效提高回收量并使逆向供应链中第三方利润和顾客效用增加,但正向供应链成员利润和顾客效用会减小;利润共享−费用分担契约和授权−最优回收数量契约都可以实现有效协调;协调后供应链中各主体企业的利润和顾客效用得到改善。

In order to study the coordination problem in the closed-loop supply chain with third-party structure under the government multi-policy situation and based on multi-policy and retailer dominance,three cases of supply chain models are established,and the optimal pricing decisions and profits in the supply chain under different conditions compared and analyzed.The results show that the government can effectively increase the amount of recycling and increase the profit of the third party and customer utility in the reverse supply chain,but decrease the profit of the retailers and manufacturers and customer utility in the forward supply chain;and that the efficiency loss is caused by decentralized decision.A profit and expense sharing contract and authorization-optimal recovery quantity contract are designed to improve the profit of supply chain members.By coordination,the profit of supply chain members and customer utility are improved.
