快递包装混合回收闭环供应链决策与协调

Decision-making and Coordination of Closed-loop Supply Chain for Mixed Recycling of Express Packages

目的优化协调快递包装回收闭环供应链参与者的利益,促使提高废旧包装物回收率。方法运用博弈论方法,构建由快递包装生产商、快递公司、互联网回收平台和消费者组成的闭环供应链模型,计算和比较在分散决策和集中决策时的利润,引入收益共享契约进行协调。结果集中决策显著优于分散决策;协调后参与者的利润比协调前的有所提高,利润提高的幅度取决于协调比例大小,数值算例验证了该结果。结论收益共享契约协调机制能够提高供应链系统利润,激发参与者积极回收快递包装,减轻对环境的污染,实现企业、消费者和社会共赢。建议政府积极推广“互联网+”的混合回收。

The work aims to optimize and coordinate the interests of participants in the closed-loop supply chain of express packaging recycling and promote the improvement of the recycling rate of packaging wastes.Based on the method of game theory,a closed-loop supply chain model composed of express packaging manufacturers,express companies,Internet recycling platforms and consumers was constructed,the profits in decentralized decision-making and centralized decision-making were calculated and compared,and the revenue sharing contract for coordination was introduced.The results showed that centralized decision-making was significantly better than decentralized decision-making.The profit of participants after coordination was higher than that before coordination,and the range of profit increase depended on the coordination proportion.A numerical example verified the results.The following conclusion is made that the revenue-sharing contract coordination mechanism can improve the profits of the supply chain system,stimulate participants to actively recycle express packaging,reduce environmental pollution,and achieve a win-win situation for enterprises,consumers and society.The government is recommended to actively promote"Internet+"mixed recycling.
