乳制品物流供应链动态模型及其鲁棒H∞控制

摘要

文中针对乳制品物流供应链系统实际运作过程中存在的时滞、参数和外部环境输入等不确定性问题，建立了相应的乳制品物流供应链动态模型，采用鲁棒H∞控制的方法和线性矩阵不等式（LMI ）算法处理了乳制品物流供应链系统实际运作问题。借助乳制品物流供应链库存状态的静态反馈控制，使供应链动态系统达到克制不确定性因素干扰的作用，并使供应链系统实际运作总成本达到最优。最后，通过Matlab仿真计算验证了所得结果。%Aiming uncertainty Delay dairy supply chain logistics systems that exist in the actual operation of the process, the input parameters and the external environment,the establishment of the corresponding dairy logistics supply chain dynamic model using the method of robust H∞ control and linear matrix inequality (LMI)algorithm processing the dairy supply chain logistics system is actually functioning.With the dairy supply chain logistics static feedback control inventory status,dynamic supply chain system to achieve the role of restraint uncertainties interference,and the actual operation of the supply chain system to achieve optimal total cost.Finally,Matlab simulation to verify the results obtained.
