模糊需求环境下的三级供应链协调机制研究

Research on Coordination Mechanism in Three-Stage Supply Chain under Fuzzy Demand Environment

研究一个由供应商、分销商和零售商组成的三级供应链系统在模糊需求环境下的协调机制。需求函数中的参数视为三角模糊数,分析模糊环境下的分散决策和集中决策过程,给出收益共享契约机制下的决策模型。最后通过一个数值分析表明,在模糊需求环境下,收益共享契约机制同样可以实现供应链中各成员间的协调。

In a three-stage supply chain composed of a supplier, a distributor and a retailer, the coordination mechanism in fuzzy demand environment is researched. The parameters of demand function are regarded as triangular fuzzy numbers. The decision processes are analyzed under the decentralized and centralized decision, and the decision model under revenue sharing contract mechanism is built. In the end, for direct analysis, a numerical example is given which suggests that the revenue sharing contract can also coordinate the profits of members in fuzzy demand environment.
