Abstract: The uncertain lead time become an important factor in replenishment decision on account of component innovation and the dynamic of supplier selection. The uncertain lead time are introduced into the study of Supply-hub collaborative replenishment to investigate the issue of supply hub cooperative replenishment decision making for two customized products with three supplier and single manufacturers, under the random lead time and the uncertain demand, and the factor of component matching is taken into consider. Three replenishment strategies are proposed and supply chain collaborative replenishment models under different strategies were established. The results of comparing the supply chain cost changes under different strategies show that there is a unique optimal replenishment volume for all three replenishment strategies. Two kinds of cooperative replenishment strategies based on Supply-hub (CRP and JRP) and independent replenishment strategies based on decentralized decision (DRP) have their own advantages, however, CRP is better than JRP. Finally, MATLAB is used to analyze the example and verify the conclusion, and the CRP can effectively reduce the risk of increasing the demand caused by the uncertainty of demand. The impact of the lead-time fluctuation on the expected operating costs of the supply chain is higher than the impact of the lead-time fluctuations in the supply chain. Therefore, more attention is paid to the lead-time of the general part when choosing the replenishment strategy for the supply chain.Our research has expanded the modelofsupply chain collaborative replenishment and provided reference for the supply-hub application in manufacturing customized supply chain inventory management.
