Tina Vo said: Has anyone explain how long would this game take? I don't know how to start this game. Thanks

gunawan jasuya said: can you explain about this section?

Terry Fillmer said: This is very difficult. When you think you have ordered enough beer, you run out. I increase orders and it is easy to get overstocked. It is a constant challenge to keep up with customer demand

Ketan Varia said: Their is a mistake in the Expert Round - in the 3 or 4th step - the requirement goes up by a step of 2, even though been placing order in batches of 10

Jubbar Arshad said: Wow very confusing. Last time I tried it I did reach equilibrium on 8th week. Lost all data. trying again.,I found it to be a little bit confusing.

patricia realini said: novice only takes one input of 25 and then nothing but 15's to solve it by week 4

patricia realini said: this simulation is easy. in expert mode, punch in 0 and then the next week 20 and then all 50's after that and you'll be at normal production by week 5.

Ryan Perkins said: The stated objective of the game should be clarified: equillibrium is where finished goods inventory does not change over the period (i.e. from its beginning to its end). The amount carried in inventory is irrelevant to this problem; rather its about being able to match production with demand.

Michael Freitag said: In the expert modus, some of the unfilled orders seem to be cancelled. Does anybody know the rule behind this cancellation? Thanks.

Gokhan Y said: thank you for free submission. i enjoyed the game, i am currently doing MBA

Mumbi King'ori said: really exciting.. problem comes when trying to predict to know how much to order

Ali Ornek said: good

Jacqueline Clemons said: Customer order 10 cases, thereafter, order 20 cases, in inventory is 15 finished goods, therefore, 15 orders are back order

Jacqueline Clemons said: customer order 10 cases, thereafter, they order 15 cases which left 5 orders on backorder.

Near Beer Game

It's called the Near Beer Game because, although it's not identical to the original beer game, it teaches many of the same lessons. It also teaches one extra lesson not in the original game: even with perfect information, even when there are no breakdowns in communication, you'll still feel the bullwhip effect due to procurement and manufacturing delays.

Here's how the Near Beer Game works: at the beginning of the simulation your supply chain is in perfect equilibrium. Customers are ordering ten cases of beer each week, you have ten cases in inventory, ten cases are brewing, and ten cases worth of raw materials are arriving from your vendors. In week two, demand increases to fifteen cases per week and remains at fifteen cases for the remainder of the simulation. The game ends when you manage to get your supply chain back in equilibrium for fifteen cases of beer.

Sounds easy right? Try it out and see how many weeks it takes you. See if you can bring the supply chain back into equilibrium without the bullwhip oscillations of stock-outs followed by over-supply.
