【Abstract】 In this paper, the effect of delay in the supply chain to the bullwhip effect is researched. The multi-stages inventory control system model of the supply chain is established, the block diagram and transfer function is given; the critical condition of stability of the whole supply chain is presented. This paper claims that the synergetic effect of system delay and gain make the sub-system in the supply chain attenuation oscillation or diffused oscillation, which is the source of bullwhip effect. Finally, four actions that can be taken to mitigate the bullwhip effect is presented.更多还原
