From the data of my team,it indicates that the variability is a bit higher than normal.Associated with the process we played the game,the main reason maybe existed in the wholesaler and the distributor(trader in the chart).As the demand of the customer went up,distributor and wholesaler didn't place enough orders to the upper one in the supply chain causing that they didn't have enough goods to meet the orders as time went on. 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:Batching ordering,Price fluctuation,Inflated orders,Demand forecasting and Long lead times. 2.Compare the changes of the bullwhip effect under different modes. Comparing the three different conditions,we can get the conclusion that: 1.The decreasing in lead time will decrease the bullwhip effect. 2.Centralized demand information can significantly reduce the bullwhip effect, but will not eliminate it.

The increase in variability in Barilla's supply chain is because that Barilla delivered product to Barilla's distributors on basis of whatever orders those distributors placed with the company.Barilla's customers were simply unwilling to give up their authority to place orders as they pleased.Some were even reluctant to provide the detailed sales data upon which Barilla could make delivery decisions and improve its demand forecast.Barilla can solve the increase in variability in supply chain by centralizing demand information,which can significantly reduce the bullwhip effect.
