摘　　要：采用传统统计学库存策略和线性控制理论方法相结合,着重研究了具有O-S反馈控制的一级动力学库存模型,提出可以采用延迟订单反馈和实际库存反馈来定义目标库存的大小。借助动力学仿真模型得到的转移方程来研究当采用跃迁输入时,实际库存水平和订单水平的变化,通过调节反馈控制参数Ks、Ko可以改善系统输出值,找到合理的库存位置。通过对动力学系统频率响应曲线的分析,得到量化牛鞭效应大小的方法,从而找到实际工作环境下,合理缓解牛鞭效应的新方法。Statistics and linear control theory was applied to study the one-level inventory model ,which has the O-S feedback control system. In particular, the target inventory with the delay-order-feedback and actual-inventory-feedback is defined and the inventory level or order level through the transfer function which derived from the dynamics inventory model is studied. The key parameters K, ,Ko are proved analytically to be used to alleviate the inventory or order fluctuation effectively. Finally, the frequency plot is analyzed to get the Bullwhip Effect formula and applied to the practical work.
