市场需求不确定的绿色供应链协调策略

Research on coordination of green supply chain with uncertainty of market demands

为了实现绿色供应链整体利润的最大化,同时提升产品的绿色度,解决经济增长与资源保护、生态环境之间的矛盾,本文以市场总体需求为随机变量的两节点的绿色供应链为研究对象,建立了绿色供应链模型,该模型中的市场实际需求受价格及产品绿色度两因素共同影响,并设计收益共享契约及其参数使所建立的供应链模型达到完美协调,并利用数值算例验证结论的正确性。研究表明,供应链集中控制模式下,供应商与零售商的利润以及市场产品的绿色度高于供应链分散控制模式,而通过收益共享契约可以实现供应链的协调,使供应商与零售商的利润以及市场产品的绿色度达到集中控制模式的水平。

The two-node green supply chain bases on the random variable of market demand are studied and a green supply chain model is established in this paper, in order to maximize the overall profit of the green sup- ply chain by designing coordination contract, as well as to improve the green degree of the product to resolve the contradictions between conservation, ecological environment and economic growth. The revenue sharing contract and its parameters are designed to coordinate the supply chain, and a numerical example is used to validate its correctness. The market demand is actually influenced by the price and the green degree.The re- sults show that the centralized control mode, the supplier profits and the retailer profits together with the green degree of product in the supply chain are all higher than those of the supply chain decentralized control model. The supply chain coordination can be realized by the revenue sharing contract, which can make the supplier profits, the retailer profits and the green degree of product to achieve the centralized control.
