An important phenomenon, known as the bullwhip effect, indicates that the variation of orders is amplified as one moves upstream in a supply chain. In this paper, we propose an analytical model to quantify the bullwhip effect by integrating the information sharing and the risk pooling strategies. The developed technique shows that the increase in variability across a three-stage supply chain can be reduced while information sharing and risk pooling are adopted simultaneously. Further, the numerical analysis suggests that our approach outperforms the existing approaches which employ information sharing or risk pooling separately in terms of controlling the bullwhip effect.
