模糊需求下三级供应链利润共享契约模型

Profit-sharing contract model in three-level supply chain under fuzzy demand

基于可信性理论和博弈理论,研究了模糊需求环境下由制造商、分销商和零售商组成的三级供应链的协调问题.通过对分散决策模型和集中决策下最大利润理想模型的分析,设计了供应链利润共享契约协调模型.在合理调整和计算利润分配参数下,使供应链节点企业实现利润共享.并用算例验证了该模型能够使得供应链各企业在市场模糊需求环境下达到有效协调并使之利润最大化.

Based on the credibility theory and game theory,the coordination problem of three-level supply chain is studied under the fuzzy demand,which is composed by the manufacturer,distributor and retailer.Through the analysis of the decentralized decision model and the ideal model of the maximum profit under the centralization decision,the coordination model of profit-sharing contract is designed,which makes the node enterprises in the supply chain share profit when the profit distribution parameters are adjusted and calculated reasonably.The example is used to verify the model which can make the enterprise effectively coordinate and make the profit maximization in the market supply of fuzzy demands environment.
