供应链库存模型联合决策的研究

Joint Decision for Supply Chain Inventory Model

本文对由一个供应商和多个客户组成的两级供应链进行了研究,建立了以平均库存成本为目标函数的供应链管理库存模型。分别采用了分散决策和联合决策对目标函数进行优化,获得了供应商的最佳生产时间间隔和客户的最佳订货次数。为了保证供应链中各成员均可获利,在联合决策模型中引入了补贴机制。数据分析和敏感性分析表明,基于补贴机制的联合决策要明显优于分散决策,在联合决策下供应链各成员平均库存成本显著降低。

The paper investigates two-echelon supply chain consisting of one vendor and multiple customers, and establishes two different optimization methods based on the joint and independent decisions. The best production interval of the vendor and the order times of each customer are well estimated correspondingly. In order to make saving for all members in the supply chain, the subsidy is applied into the joint decision method. Numerical example and sensitivity analysis show that the joint decision using the subsidy is better than the independent decision because all members gain significant savings.
