| Abstract: |
| [Objective] Based on the inventory strategies, the predicted error in supply chain was studied.[Methods] The stability condition was obtained through linear stability analysis.The influence of error originated from varied condition such as inventory and market was simulated respectively.[Results] The results show that optimizing the inventory forecasting strategy to reduce the forecast error can reduce inventory fluctuations and enhance the system stability.The results also indicate that the decrease of the delay time can reduce the influence of market disturb and make the system stable.[Conclusion] These results are significant and useful for controlling and reducing the Bullwhip effect. |
