摘要
牛鞭效应的存在严重影响了供应链系统的运作效率,增加了供应链管理的复杂性。本文基于供应链网络库存状态的内部系统动力学机制,构建了供应链网络库存系统的状态转移模型,并引入时滞影响因素,通过供应链网络库存系统的波动状态描述牛鞭效应。在此模型基础上,针对供应链网络系统的牛鞭效应问题,提出了一类新的基于库存波动状态的动态供应链库存控制策略,并运用系统稳定性理论,将该策略的参数优化求解问题转化成线性矩阵不等式的求解问题。最后通过系统仿真深入分析了供应链网络库存系统对库存控制策略参数以及系统时滞因素的敏感性,并验证了该动态库存控制策略可以有效地抑制牛鞭效应。
The bullwhip effect problem has been recognized as one important topic in supply chain management.It brings bad effect on supply chain performance and reduces the efficiency of supply chain management.Based on the dynamic characteristics of inventories in a supply chain network,a supply chain inventory system state transition model is presented,which includes the operation lead time delays in system.Then a dynamic inventory control method is proposed to reduce the bullwhip effect.Based on the control theory,the solving process of the proposed inventory control method is presented.Further,the effect of lead time delays on inventory control performance of supply chain networks is studied.Simulation study shows the effectiveness of the proposed inventory control method in reducing bullwhip effect and in improving supply chain performance.
