中文摘要 | 本研究旨在提出一反應多階層需求式之最適化物流控制策略,以有效地舒緩供應鏈產生的長鞭效應。本研究以動態隨機最佳化控制方法論,提出一估算隨時間變動之需求導向物流控管模式,以動態反應供應鏈中直接與間接下游成員之需求,並在系統性最佳化供應鏈各組成績效之目標前提下,以隨時間變動權重之估計量推估需求;此外,本研究並提出一實驗設計,以兩個準則驗證前述模式。實驗結果數據顯示,相較於其他現存模式,本模式確實能夠有效減輕供應鏈之長鞭效應;同時,本研究應用之方法論,有助於解決各供應鏈組成間需求資訊不確定性與複雜性之議題,將可有效地增進整體供應鏈之協調性。 |
英文摘要 | This paper presents a multi-layer demand-responsive logistics control strategy for alleviating, effectively and efficiently, the bullwhip effect of a supply chain. Utilizing stochastic optimal control methodology, the proposed method estimates the time-varying demand-oriented logistics system states, which originate directly and indirectly downstream to the targeted member of a supply chain, and associate these estimated demands with estimated of different time-varying weights under the goal of systematically optimizing the logistical performance of chain members. In addition, an experimental design is conducted where the proposed methods is evaluated with the two specified criteria. Numerical results indicate that the proposed method permits alleviating, to a great extent, the bullwhip effect in comparison with the existing logistics management strategies. Furthermore, the methodology presented in this study is expected to help address issues regarding the uncertainty and complexity of the distortion of demand-related information existing broadly among supply chain members for an efficient supply chain coordination. |
