What Is Bullwhip Effect?

Here there is an excess supply amount, so there are more computers than that are actually wanted. At this point, the sellers would recognize there are fewer buyers for their product at the current set

Retail super-giant Wal-Mart has fought its way to becoming the world's largest company. Wal-Mart’s legendary supply chain technology has allowed them to break the three-day barrier that some economists in the eighties felt that it was unbreakable. In other words, Wal-Mart is often able to replenish items on the Wal-Mart shelf in less than three days – not from the central warehouse to the shelf, but from the manufacturer to the shelf. With quick and reliable 2-day turn around, Wal-Mart is able to maintain lower levels of inventory and still meet customer demand. These lower inventory levels result in either a reduced floor plan with lower carrying costs and lower interest expense – or a greater diversity of products on the store shelves.

Dell uses a just in time order fulfillment policy and accurate forecasting of sales to minimize inventories. This allowed Dell to hold inventory of finished products far below levels of their competitors (10-20% compared to 50-70% industry level) and furthermore allowed them to quickly implement changes to their product lines as new technologies became available. This quick inventory turnover also allowed Dell to retain more capital. Finally, this policy enabled Dell to respond immediately to technological progress in components and deliver state of the art new finished products (e.g. Pc’s holding the newest Pentium microprocessors) while competitors

The supply chain management is considered as a management concept from past two decades as the customers are concerned about timely and safe delivery. The competitiveness has been increasing among the companies to deliver the products as quickly as possible to the customers all around the world. This has made the supply chain management as a vital tool for the management. This is also measured as a competitive parameter for the companies.

Reduced need for higher capacity at the supplier. This would be reduced because suppliers would not need to size their operations to deliver on the “one shot large volume order” and would be able to space these in time with orders at

In the Fixed-Order Quantity Model (Q-Model), every time that the stocks reach a specific level an order is placed. Q-Model requests a constant monitoring in inventory levels. The risk of stock out only occurs during the lead time, thus the safety stock is less than in P-Model for the same service level. Reorders are placed when stocks reach (R), and the safety stock that must be reordered is:

These spikes and troughs could be the result of price discounts that the company is offering due to which customers are buying in bulk and stocking up on products. This could lead to variability in demand, leading to excess demand or no demand that would lead to non-efficient production by the company. Root cause analysis should be performed, and if it is established that volume discounts are leading to this phenomenon, it is recommended that the company minimize discounting and work with the customers using a partnership model to ensure a steady demand.

Barilla, the leading pasta manufacturer in Italy, faces increasing problems related to demand fluctuation. Their distributors also suffer from high inventory holding costs and low service levels on the other hand. This report explains, why the company and their distributors are troubled with this situation and how Barilla intends to solve it. The problem Barilla experiences is called the “Bullwhip Effect”, i.e. that demand variability increases when moving up the supply chain. Several factors enforce this Bullwhip Effect, e.g. high lead times, poor demand forecasting, and batch ordering. In this report we will point out, that exactly those aspects can be identified as the underlying reasons for Barilla’s problems. In a

Observe Exhibit 12. What are the underlying causes and drivers that make order patterns to look this way? Provide a discussion on these causes/drives to show how they are causing the resulting demand pattern. Examples of items to consider include transportation discounts, promotional activity, product proliferation.

First, great job with your example of a shortage. While I was working at a local clothing store the Yeti cup was always on a high demand. We placed the cups in the front of the store so consumers would be sure to see them as they first walked in, and they were also near the checkout line so while customers waited in line they would be bombarded by even more Yeti products. Around the Holidays the store would experience frequent shortages of Yeti cups. Sometimes the Yeti cups would be on back order for 6 months or more. The store I worked for did exactly as you stated we would buy a similar product to the Yeti such as the Orca. This would drive the demand of the Yeti cup down and still make sure the store gained a profit.

My inventory control procedures provided both increased revenues and cost savings. Quite simply, I ordered adequate levels of products which were in high demand, I was able to better meet customers’ needs, and my revenues increased. The cost savings I experienced as a result of my inventory control procedures were a bit more complex. First, in establishing a routine schedule for ordering, I was able to reap the benefits of lower shipping costs. Because I had a routine schedule, I could

Chabot needs to increase the flexibility in its supply chain. Chabot is an innovative product manufacturer trying to utilize an efficient supply chain. In order to be able to meet demand, the company needs to deploy excess buffer capacity. Lead time is not up to par so Chabot needs to increase its inventory if it plans to meet unpredictable demand. This will also help increase Chabot’s level of

Lead time varies significantly, which affects the inventory cycle. The plant has to set a safety stock that will protect the production against stock outs, vehicle breakdowns, weather related delays and the shortage of supply from farmers and hogs barns.

Along with better communication, improved forecasting can help a supply chain run better. If you are able to forecast customer demand, you have a better chance on not being “tricked” by signals throughout the chain. A company can improve forecasting by looking at their past history, the history within their industry, or simply by asking their customers; predominantly through surveys or focus groups. Another way to improve you supply chain is to see if there is an opportunity to reduce the number of parties or complexity within the supply chain. The more stations there are the better chance for errors and delays. It is also easier to find and solve issues if your process is less complex. A smaller group also allows for better relationships between

Piggy Poopy apply the Safety stock to ensure that the raw material will not be running off because sometimes supply and demand of the customers will not goes to the same way. So, the company keeps the raw material for 10000 units produced to prevent the shortage. Moreover, we stock the raw material because sometimes there is shortage of raw material and it affected the price increasing. It causes the cost per unit increasing so we will get low profit and sometimes we increase price of our product. Moreover, the customer will buy less because price is increasing but quantity is the same. For this reason we should have a safety stock to prevent chaos that would
