System Dynamics Modeling and Simulation of multi-stage Supply chain: The value of information sharing
The important phenomenon called bullwhip effect suggests that demand variability increases as one moves up a supply chain. This 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 paper analyzes the bullwhip effect in the condition of no demand information sharing and demand information sharing. The value of demand information sharing will be very high, and the reduce ratio of manufacturer, distributor and wholesaler is 65%, 64% and 62% respectively. But the bullwhip effect of retailer has a slight raise.
