| 摘 要： | 分析供应链中各节点企业订货的动态过程,建立各企业订货量的离散时域模型并通过Z-变换,将离散时域订货量模型转换为以需求量为输入、订货量为输出的传递函数模型,说明企业订货量随需求量变化而波动的过程.比较信息共享前后企业订货量的波动情况,了解信息共享改善供应链订货量波动的程度.

| Abstract: | The dynamic order process of each node enterprises in the supply chain is analyzed and the discrete time domain model of the order quantity is established. Then through Z-transformation, the discrete time domain model is transformed into a transfer function model, in which demand quantity is the input while order quantity is the output to present the fluctuating process of the order quantity in accordance with demand quantity. The fluctuation conditions of the order quantity before and after the information sharing are compared to study the rote of information share in the reduction of order quantity fluctuation in supply chain. |
