The results show that with short lead time,the system cost has reduced by a large margin.The mean of retailer and wholesaler rises and the SD of them reduce.The mean and SD of the factory don't change much. 6.Conduct the game for the third time by centralized system and analyze the result.

The origin system has the maximum system cost,the centralized system has a less system cost and the system with short lead time has the minimal system cost.In the centralized system,since the information can be exchanged,it has no mean and SD Compared to the origin system,the system with short lead time has a bigger mean but the SD is lower.So we can know that both shorten lead time and exchange information can reduce the bullwhip effect and get a lower system cost. Answer the Questions 1.Conducting the Beer Game by Software has the advantage of various modes,please list the factors that can affect the volatility of the supply chain data(bullwhip effect). The main factors contributing to the Bullwhip Effect are:Demand forecasting,Lead time,Batch ordering,Price fluctuation and Inflated orders. 2.Compare the changes of the bullwhip effect under different modes

Compare the changes of the bullwhip effect under different modes
Shorten the lead time will decrease the bullwhip effect.Centralized demand information can significantly reduce the bullwhip effect. 3.Make a comprehensive analysis for different modes and provide some suggestions for the case of Barilla SPA(A)in the text. Barilla can reduce the bullwhip effect by centralizing demand information and improve the produce process,short the lead time
