Beer Game 金梦珂1120329011 Process of the Beer Game 1.Strat the game,and then the first round begins. 2.The retailer places an order to the wholesaler based on the customer's demand and historical data. The wholesaler places an order to the distributer based on the retailer's demand and historical data. The distributer places an order to the factory based on the wholesaler's demand and historical data. The factory decides the quantity of goods to produce based on the distributer's demand and historical data. 3.The first round ends and the next round begins.Repeat the operation until the game ends. (about 15-30 rounds) 4.After the game,get the corresponding data and graphs.

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 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 results are:

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
