Abstract: To realize the low cost robust operation of dynamic supply chain system with consideration of lead-time reduction,a cost optimization strategy and the robust control method were researched.A kind of quantitative model of compressive cost and compressive amount was established for the lead time,and a cost optimization strategy was proposed by comparing the compressive cost with the shortage cost under different inventory levels.According to the different inventory statuses of each node enterprise in supply chain,a model of dynamic supply chain considering lead-time compression was constructed,and a fuzzy robust control method was applied to realize the flexible switching among models.A simulation example of dynamic supply chain was given to show that both the total cost could be reduced and the robust stability could be realized with the cost optimization strategy and the fuzzy robust control.

Key words: dynamic supply chain, lead-time compression, robust control, inventory level, cost optimization strategy
