Bullwhip effect is a theory that the farther a company gets away from the customer, the more variable the demand is. This makes no sense -- it's like saying the more stocks you have in your portfolio the more volatile it will be. What happens is not a bullwhip at all. Look -- a 5% change in demand is a 5% change in demand up the entire stream. If the front-line retailer is in line with the industry change, then that means everybody in the industry is going to see a 5% change in demand. The raw number change in demand up the supply chain is bigger, but it's still the same percentage. The producer is a bigger company to begin with, so it is equipped to handle this change to the same degree that the retailer is. Furthermore, if the 5% change at the retailer level includes some component that is specific to that one retailer, than the industry change is going to be much less than 5% - in other words less volatile. Diversification decrease volatility, because you have to look at this on a percentage basis. Looking at raw numbers, when the producer is operating at a much larger scale than the individual retailer, makes no sense. Indeed, a quick look at the explanation for the bullwhip effect tells me that it is a fiction. The following can contribute to the bullwhip effect: overreaction to backlogs, neglecting to order in an attempt to reduce inventory, no communication up and down the supply chain, delay times for information and material flow (QuickMBA, 2010). If these are the causes, then these are the causes. It...
The terminology and definition of bullwhip effect pins the blame on the change in demand when clearly it is the inventory management practices, and not the change in demand, that create this effect.
Bullwhip Effect: What causes it and using ECR and VMI to counteract its effects "The bullwhip effect occurs when the demand order variabilities in the supply chain are amplified as they moved up the supply chain" (Lee, Padmanabhan & Wang 1997). The bullwhip effect could be characterized as a kind of a gigantic game of 'telephone,' in which the first message becomes distorted in the retelling, and subsequent transmissions of the information
CPR Model and Bullwhip Effect CPFR (Collaborative Planning, Replenishment, and Forecasting) is a growingly applied business practice aiming to lower supply chain spending through the promotion of increased cooperation, integration, and visibility between supply chains of trading partners. The phrase "trading partner" is applicable to nearly all combinations (inter, as well as intra) of manufacturers, suppliers, retailers, or distributors. CPFR itself represents an extension of older collaboration efforts such as just-in-time
absence of it, help to create the bull-whip effect? What feedback would you like to have, specifically, as you determine your weekly orders for Kentucky Swamp Brew? How would get such information? When would you like to have it? "As beer consumers develop a taste for more refined small-batch brews, the craft beer industry is steadily growing, and so is the need for beer supply chain management solutions" (Skrbek 2014)
ordering strategy is fairly simple, and this is why there were seldom backlogs. Basically, what you want to do is understand the baseline demand. In the real world, we would probably already have this data, but in the simulation we needed to figure that out. So most of the order backlogs occurred initially, and during promotion, when nobody was really certain of demand. Once it was established that demand
BWE In business, one of the most challenging issues is what is known as the Bullwhip Effect (BWE) in the supply chain. This effect means that any demand forecast attempt cannot be accurate, since it is based on potentially inaccurate data. According to Ravichandran (2008), BWE refers to a distortion in the demand forecast related to a noise factor. The demand is therefore inflated and leads to an increase in fixed
In that situation, I could get a much better idea of when I could expect the backlog to clear and why the supplier was unable to meet my order requirements. I could also have used that information to convey to my customer my expectations of when I would be able to fulfill their orders. Having this ability to extract information would be very helpful. "While one strategy may work
