摘要
以四级两单链的集群式供应链为研究对象,在两个单链相互竞合条件下,建立了两单链间两零售商跨链间库存协作的时变鲁棒控制系统模型,以及牛鞭效应的弱化方法,并用H∞优化算法来求解动态最优决策.通过实例分析表明,集群式供应链跨链间协调及鲁棒优化能有效抑制牛鞭效应、降低库存水平,在减小订货波动的同时可提高对集群市场的响应速度.
On the basis of cluster supply chain with two four-echelon single supply chains, the cross-chain inventory coordination between two retailers is taken into account under the condition of co-petition between the two supply chains. The time-varying robust control system model is built. The method of the slacking bullwhip effect is then put forward, and dynamic optimal decisions are also explored by using the H-infinity optimization algorithm. The simulation example shows that the cross-chain inventory cooperation in cluster supply chains and the robust optimization method effectively weaken the bullwhip effect, reduce the stock, dwindle the fluctuation of order and improve the response to cluster market.
