Bullwhip Effect and the Beer Distribution Game. Yesterday for class, we played the Beer Distribution Game, which is a game developed by the Systems Dynamic Group at MIT back in the early 1. This game simulates what can happen in a traditional supply chain and exposes some interesting dynamics that happen in real world supply chains and invites us to think about the positive impact a lean fulfillment stream would have and overall logistics management. Kanban Simulation Dot Game' title='Kanban Simulation Dot Game' />The players of this game take on the role of Retailer, Wholesaler, Distributor, and Factory. The retailer sells barrels of beer to a consumer and orders barrels of beer from the wholesaler, the wholesaler sells barrels of beer to the retailer and orders barrels of beer from the distributor and the distributor sells barrels of beer to the wholesaler and orders beer from the factory brewery. The factory brews the beer. The beer supply chain is shown below Each player is directly linked, and beer cannot skip the adjacent position. For example, the Wholesaler orders beer from the Distributor, and ships beer to the Retailer. The goal of the game is to minimize team total costs each barrel of beer has a cost, which is calculated at the end of the game. Information Flow proceeds from Retailer to Factory Material Flow proceeds from Factory to Retailer. The order quantities of the retailer was the same after week 4. From week 1 4, the order quantities was 4 barrels. From week 4 until the end of the game, the order quantity was 8 barrels. But, the players didnt know this fact. This is what the order quantity chart looked like Despite the contant order quantities for the entire game, the results are very surprising this is what demonstrates the Bullwhip Effect In the studies conducted with a simple four step supply chain, small variations in initial demand could lead to order amplitudes of 9. These studies demonstrated that the main cause for erratic fluctuations of order sizes and inventory levels in supply chains was actually not the amount of uncertainty of the demand function but the characteristic of the supply chain and the behavior of the supply chain managers. Ive experienced the Bullwhip Effect, and I can tell you that I have not learned to effectively manage it or avoid it. But, below are some true and tried principles for how to manage the Bullwhip Effect The Bullwhip Effect or Whiplash Effect is an observed phenomenon in forecast driven distribution channels. The concept has its roots in J Forresters Industrial Dynamics 1. YahooURL. Dont bore your team with static Powerpoint slides Engage them with a Lean game to demonstrate your teaching.

Since the oscillating demand magnification upstream a supply chain reminds someone of a cracking whip it became famous as the Bullwhip Effect. Yesterday was a fascinating study into human behavior. As I walked around the room, I heard phrases such as lets assume orders will always be between 5 and 1.

Bullwhip Effect and the Beer Distribution Game teaches us about the impact of variability in a supply chain. Without knowing it, the players yesterday over and under forecasted they over compensated on inventory they tried to rush production and didnt follow pace system and human behavior that is so classic in real Operations and Supply Chains. Below are a few videos that show how to simulate supply chain shocks and issues that arise in managing supply chains. Below is the Beer Distribution Game. The Beer Distribution Game The Beer Game is a simulation game created by a group of professors at MIT Sloan School of Management in early 1. Kanban Simulation Dot Game' title='Kanban Simulation Dot Game' />The game is played by teams of at least four players, often in heated competition, and takes from one to one and a half hours to complete. A debriefing session of roughly equivalent length typically follows to review the results of each team and discuss the lessons involved. The purpose of the game is to meet customer demand for cases of beer through a multi stage supply chain with minimal expenditure on back orders and inventory. Devpro Deck 2014 more. Players can see each others inventory but only one player sees actual customer demand. Verbal communication between players is against the rules so feelings of confusion and disappointment are common. Players look to one another within their supply chain frantically trying to figure out where things are going wrong. Most of the players feel frustrated because they are not getting the results they want. Players wonder whether someone in their team did not understand the game or assume customer demand is following a very erratic pattern as backlogs mount andor massive inventories accumulate. During the debriefing, it is explained that these feelings are common and that reactions based on these feelings within supply chains create the bullwhip effect. Larry Navarre To begin with, a few acknowledgements. First to Provost Simpson for the opportunity to do this. It actually caused me to learn something I didnt realize and Ill hopefully have a moment to talk about that later. Colleagues, students, especially Im delighted to see students here and Dr. Terri Lynch Caris. Id forgotten but I recall that the beer game actually came from her suggestion, so I have a great debt of gratitude to you. Its been a great fabulous exercise for me and my supply chain courses and so I greatly appreciate that. With me is Dr. Thomas Ngniatedema. Dr. Ngniatedema is going to be helping me with the data entry so that during the game, I can interact more freely with the participants. I really had a hard time with the title of this speaker series because Im either the indistinguished or the non distinguished professor. I want to emphasize that perhaps Im distinguished in different ways, given my experience before Ive come here at Purdue. Ive always wanted to teach at the collegiate level and so its a great pleasure to be at Kettering. Ive only been here four years. Im very new. As youve heard, Im not a doctor. In the business department, we like to call ourselves pracademics and thats a practitioner whos gone to the dark side to become an academic. No research yet. Even as we were looking at this, maybe theres some opportunities in the area of innovation development, which has been my primary focus of new coursework and has been my long term joy in my career, has been the process of business process of product development. So supply chain management to me, when I was in industry, was a buzzword. Itd been going around and people had been talking about it, but now I actually teach it. Imagine that. Supply chain. What is a supply chain Its all the activities involved directly or indirectly in fulfilling a customer request. And this typically includes the suppliers, manufacturers, transporters, warehouses everybody in the supply chain out to the customer, but it also includes within each company, the functions involved in fulfilling a request. And Im delighted to see that Professor Chopra from Northwestern University has identified product development, because it kind of begins there, with the new ideas and things that are the innovations that are coming into the organization and of course, through marketing operations, distribution, finance and customer service. Supply chains are dynamic network systems that require effective coordination of information up and down the supply chain. Generally, we look at supply chains this way, and Thomas and I use a text that has this illustration in it, talking about people who want ketchup. And so the consumers here buy from the retail grocery store, who gets it from the ketchup factory.
