摘要：
Bullwhip effect seriously affects the operation efficiency of supply chain networks and management complexity. In order to reduce these effects, system dynamic mechanism is built for inventory level in supply chain networks firstly. Due to the demand disturbance of customers, the inventory fluctuations of vendors or suppliers are used to measure bullwhip effect which based on one of linear and time-invariant policies, order-up-to policy. Since the complexity of supply chain network structure, a novel evaluation method is presented to measure bullwhip effect in different network topologies. Case studies show that different network topologies do not have an obvious impact on bullwhip effect, but the network size may affect how serious bullwhip effect will be.
