多层级乳品供应链网络均衡问题研究

以乳品供应链网络为研究对象,构建包含原奶供应商、乳品加工企业、乳品分销商、终端消费市场四层决策主体的乳品供应链网络均衡模型。利用均衡理论和变分不等式理论,描述每个决策者的独立行为以及决策者之间相互影响的竞争行为,采用修正投影法求出均衡解,并给出经济解释,通过数值算例验证模型的合理性和正确性。这一均衡模型有助于协调供应链中各成员之间的利益关系,提升乳品供应链整体运作效率,提高乳品行业的竞争力。

Study on Equilibrium of Multi-level Dairy Supply Chain Network

Taking the dairy supply chain network as the research object, the dairy supply chain network equilibrium model including the four-tier decision-making body of raw milk supplier, dairy processing enterprise, dairy distributor and end consumer market is constructed. With equilibrium theory and variational inequality theory, the independent behavior of each decision maker and competitive behavior of mutual influence among decision makers are described. The equilibrium solution is obtained by modified projection method, and the economic explanation is given. Therationality and correctness of the model are verified by numerical examples. This equilibrium model helps to coordinate the interests of members in the supply chain and improve the overall operational efficiency of the dairy supply chain and competitiveness of the dairy industry.
