Abstract: To reduce the impacts of internal and external uncertainties and multiple lead times on the operating efficiency of the supply chain network,a fuzzy robust control strategy was studied.The robust operation problem of an uncertain supply chain network with lead times was researched.Based on Takagi-Sugeno fuzzy control system,a discrete Takagi-Sugeno fuzzy model of the uncertain supply chain network with lead times was constructed,which included the uncertainties of production capacity,supply chain network structure,customer demand and lead times.By defining a discrete piecewise Lyapunov function in each maximal overlapped-rules group,a new fuzzy robust H∞ control strategy for the supply chain network model was proposed through the principle of parallel distributed compensation,which was suppressed the impacts of uncertainties and lead times on the supply chain network,and ensured the supply chain network robust operation.A simulation example was given to show that the control strategy could make the total cost of the supply chain network reach the ideal state,which verified the usefulness and effectiveness of the proposed strategy.
