在模糊需求环境下,研究由单一供应商和零售商组成的两级供应链系统的协调机制问题.将市场需求视为模糊变量,建立不确定理论下,基于可信性分布的集成供应链模型和收益共享契约模型,并给出了模型中的最优策略.最后,以三角形模糊变量为例,通过数值算例对模型中的参数进行了求解,并分析批发价格和收益系数对其他参数的影响.研究结果表明,零售商的最优订购量在模糊需求中心点的左、右浮动,并随着零售价格的提高而增加;不同的收益系数对应不同的批发价格策略;通过改变收益系数可以实现供应链成员之间的完美协调.

In a two-stage supply chain composed of one supplier and one retailer, the supply chain coordination mechanism is researched in a fuzzy demand environment. The market demand is treased as a fuzzy variable, and the models of centralized decision-making and revenue sharing contract are proposed based on credibility distribution. Finally, taken the triangular fuzzy number as an example, a numerical is given to illustrate the models. It shows that the retailers optimal order quantity fluctuates at the center of the fuzzy demand and increases with the raise of the retail price. The different wholesale price strategies can be got by using different value of revenue coefficient. The coordination of members can be achieved in revenue sharing contract with fuzzy demand.
