Influence of Downstream Suppliers on Current Supplier in Multiple Supply Chain

This paper proposes two models to describe the stability of multiple supply chain with consideration of downstream suppliers' influence on current supplier. Based on these models, the linear stability analysis was performed and the stability conditions were given out respectively. It shows that consideration of the downstream suppliers' influence has a stabilizing effect. Additionally, the numerical simulation was performed and the results are consistent with linear analysis results. It can be concluded that the consideration of the downstream suppliers in supply chain system can increase the stability of supply chain and reduce the bullwhip effect.
