考虑到供应链实际构成与四级供应链质量控制研究不足,本文运用stackblerg博弈分析模型,研究了由供应商、制造商、经销商与消费者组成的四级供应链产品质量控制问题。在考虑需求不确定性的基础上,分析制造商与经销商之间延期支付和货款首付比例两种策略对供应链产品质量控制水平的影响,通过运用最优化原理求解制造商和供应商的最优质量控制水平并对结果进行仿真模拟,结果显示:制造商与经销商之间非质量协调策略对供应链产品质量有间接协调作用;制造商提高经销商货款首付比例或缩短余款延期支付时间,不仅有助于提高自身产品加工质量控制水平,更有助于供应商原材料质量水平提高,制造商在运用两种策略时,必须同时考虑产品价格引致的消费者需求量的变化和质量控制对其他主体收益变化的影响。
Taking into account the actual composition of the supply chain and the lack of research on the quality control of the four-level supply chain, this paper studies the quality control of four-level supply chain composed of suppliers, manufacturers, distributors and consumers using the stackblerg game analysis model. Based on the uncertainty of demand, this paper analyzes the influence of delay payment and down payment ratio between manufacturers and distributors on the quality control of supply chain products. By using the optimization principle to solve the problems of manufacturers and suppliers The results show that the non-quality coordination strategy between manufacturer and distributor plays an indirect coordinating role in the quality of supply chain products; the manufacturer increases the proportion of down payment of dealers’ payment or shortens the payment time of deferred payment , Not only helps to improve the quality control of their own products processing, but also helps suppliers improve the quality of raw materials, manufacturers use both strategies, we must also take into account product prices caused by changes in consumer demand and quality control The impact of changes in other subjects income.
