The beer distribution game ( besides known as the beer game ) is an educational game that is used to experience typical coordination problems of a add chain procedure. It reflects a role-play simulation where respective participants play with each other. The game represents a provide chain with a non-coordinated process where problems arise due to lack of data partake. [ 1 ] This crippled outlines the importance of information partake, add chain management and collaboration throughout a supply range action. Due to lack of information, suppliers, manufacturers, sales people and customers frequently have an incomplete understand of what the real demand of an order is. The most interesting separate of the game is that each group has no control over another part of the provide chain. therefore, each group has only significant control over their own separate of the add chain. Each group can highly influence the entire supply chain by ordering excessively much or excessively little which can lead to a bullwhip effect. therefore, the orderliness take of a group besides highly depends on decisions of the early groups. [ 2 ]
history [edit ]
The Beer Game was invented by Jay Wright Forrester at the MIT Sloan School of Management in 1960. The beer game was a leave of his oeuvre on system dynamics. [ 2 ]

Rules [edit ]
In the beer game participants enact a four-stage add chain. The task is to produce and deliver units of beer : the factory produces, and the other three stages deliver the beer units until it reaches the customer at the downstream end of the chain. The goal of the game is to meet customer demand with minimal expending on back orders and armory. The game is played in 24 rounds and in each beat of the game the following four steps have to be performed :
- Check deliveries: How many units of beer are being delivered to the player from the wholesaler.
- Check orders: How many units the customer has ordered.
- Deliver beer: Deliver as much beer as a player can to satisfy the demand (in this game the step is performed automatically).
- Make order decision: Decide how many units are needed to order to maintain stock.
As previously said, there are four stages, manufacturer, distributor, supplier, retailer, with a two-week communication col of orders toward the upriver and a two-week issue range delay of product towards the downstream. There is a one-point price for holding excess armory and a one-point monetary value for any backlog ( previous backlog + orders – current inventory ). In the board plot version, players can not see anything other than what is communicated to them through pieces of newspaper with numbers written on them, signifying orders or product. The retailer draw from a pack of cards of cards for what the customer demands, and the manufacturer places an regulate which, in turn, becomes intersection in four weeks. [ 3 ] Players look to one another within their add range madly trying to figure out where things are going wrong. The team or supply chain that achieves the lowest entire costs wins. At the end during the debriefing, it is explained that these feelings are common and that reactions based on these feelings within provision chains create the bullwhip effect. [ 4 ] The game illustrates in a compel way the effects of poor people system sympathy and inadequate communication for evening a relatively dim-witted and idealize supply chain. Although players often raise the lack of perfective information about the customer orders as a primary reason for their poor team performance in the game, analysis of the minimal possible seduce using the optimum strategy under different conditions shows an expect value of perfect information of 0 for the standard game, [ 5 ] and simulations that included giving players perfect information still showed poor team performance. [ 6 ]
supply chain [edit ]
A supply chain is a network between a company and its suppliers to produce and distribute a specific product to the final buyer. This network includes different activities, people, entities, information, and resources. The issue chain besides represents the steps it takes to get the product or serve from its original state to the customer. supply chains are developed by companies so they can reduce their costs and remain competitive in the commercial enterprise landscape. It is authoritative to understand how to manage the add chain in the correct room. Supply chain management ( SCM ) is the management of the flow of goods and services and includes all processes that transform raw materials into final examination products. It involves the active streamline of a business ‘s supply-side activities to maximize customer value and gain a competitive advantage in the market. SCM represents an attempt by suppliers to develop and implement supply chains that are as effective and economic as possible. supply chains cover everything from production to product development to the information systems needed to direct these undertakings. [ 7 ] typically, SCM attempts to centrally control or link the output, cargo, and distribution of a product. By managing the provision chain, companies are able to cut excess costs and deliver products to the consumer flying. This is done by keeping tighter control of internal inventories, inner production, distribution, sales, and the inventories of caller vendors. SCM is based on the idea that about every merchandise that comes to market results from the efforts of respective organizations that make up a supply chain. Although provide chains have existed for ages, most companies have merely recently paid attention to them as a value-add to their operation. [ 8 ]
Bullwhip consequence [edit ]
The bullwhip effect ( or whip or two-handed saw effect ) is a well-known symptom of coordination problems in traditional provision chains. It refers to the character played by periodic decree amounts as one moves upriver in the supply chain toward the production end. tied when requirement is stable, small variations in that demand, at the retail-end, tend to dramatically amplify themselves upstream through the issue chain. The resulting consequence is that orderliness amounts become very erratic. very high one week, and then zero the next. The term was first coined around 1990 when Procter & Gamble perceived erratic and overstate arrange patterns in its add chain for babies ‘ diapers. As a consequence of the bullwhip effect, a crop of inefficiencies occur throughout the provision chain : [ 1 ]
- high (safety) stock levels
- poor customer service levels
- poor capacity utilization
- aggravated problems with demand forecasting
- ultimately high cost and low levels of inter-firm trust
While the effect is not modern, it is still a timely and pressing problem in contemporary supply chains. broadly, the reasons for the bullwhip consequence are : [ 1 ]
- Order batching: Happens when each member in the chain orders more quantities than it needs, warping the original quantities demanded.
- Price fluctuation: Special discounts and cost changes can cause buyers to take advantage, resulting in irregular production and distorted demand.
- Demand information misuse: When past demand information for new estimates do not take into account fluctuations.
- Lack of communication: This can lead to constraints when processes are not run efficiently, this usually happens when organizations identify the product demand differently within different links of the supply chain.
- Free return policies: Customers may overstate demands due to shortages, if customers cannot return items, retailers will continue to exaggerate their needs, cancelling orders and causing in excess product or materials.
Types [edit ]
There are several options how to play the beer game. The respective approaches are explained in more contingent below .
Traditional board game [edit ]
The traditional adaptation of the beer game is a physical control panel game where people have to move actual objects. The tokens on the board game typify orders and stocks of a add chain process. The main disadvantage is that this type of beer game takes a lot more prison term than the software version. furthermore, it is quite complex to play it since people need physical objects that represent the inventory on the board. additionally, inventory levels of early provide chain stages are diaphanous and are therefore quite hard to estimate. [ 2 ]
board adaptation [edit ]
This version of the beer game was introduced by the University of Klagenfurt. The game can be played with the use of paper slips where the players have to write numbers on top. This type of game is a more hardheaded approach path to moving orders and stock in the supply chain. additionally, there is one person with the function of a bookkeeping person that keeps track of everything happening.

Adapted [edit ]
The adapted table translation is an expand translation of the table version where the bookkeeper is eliminated to achieve a more straightforward bet on. In order to play this game a spreadsheet and a laptop on each table are needed. The laptops are used for people ‘s play sheets, which eliminates risks of miscalculating stock levels. [ 2 ]
software [edit ]
The software translation of the beer game is an on-line set about. This approach can be either used as a one player pretense presentation or as a multiplayer simulation demonstration. [ 2 ]
