多周期农产品废弃物供应链网络均衡模型构建

目的 研究农产品废弃物可持续利用问题，既实现供应链整体利润最优，又减轻对环境的污染。方法 在随机需求的背景下，考虑生产合作社对零售商的不同激励度，分析生产合作社、零售商、需求市场的最优状态，利用变分不等式建立相应的多周期供应链网络均衡模型。结果 从多周期角度，实现了农产品废弃物供应链网络均衡利益最优化，可为合作社与零售商在较长时间达到一种均衡状态提供有效解决方案。结论 既实现了多周期农产品废弃物的持续利用，又促进了循环经济的发展，同时还实现了供应链网络均衡、供应链整体利润最优和减轻环境污染等目标。

Construction of Network Equilibrium Model of Multi-cycle Agricultural Waste Supply Chain

The work aims to study the sustainable utilization of agricultural waste, so as to achieve the overall profit optimization of the supply chain while reducing the pollution to the environment. In the context of random demand, considering different incentives of production cooperatives to retailers, the optimal state of production cooperatives, retailers and demand markets was analyzed, and the corresponding multi-period supply chain network equilibrium model was established using variational inequalities. From the perspective of multi-cycle, the balanced benefits of the agricultural waste supply chain network was optimized, which could provide an effective solution for cooperatives and retailers to reach an equilibrium state for a long time in the future. It not only realizes the sustainable utilization value of multi-cycle agricultural waste, but also promotes the development of circular economy. At the same time, it also achieves the goals of balancing the supply chain network, optimizing the overall profit of the supply chain, and reducing environmental pollution.
