Abstract :
The paper starts with the Casual Loop Diagram (CLD) of each supply chain node. The system dynamics model of supply chain node is given. Based on this, the model of multi-stage supply chain consisting of manufacturer, distributor, wholesaler and retailer is given as well. The simulation results under the random demand show that remarkable bullwhip effect is exist. The sensitivity analysis indicate that the lead time has the greatest impact on the supply chain compare to the safety inventory and period of forecast.
