Introductions of bullwhip effect
According to Lee et al. (1997b) there is a phenomenon that the variance of orders may be larger than that of sales, and the distortion tends to increase as one moves upstream which is called bullwhip effect. It is a distortion in the sharing of information from downstream to upstream in the whole supply chain system; the effects can propagates the enterprise’s marketing, logistic and manufacture. Despite There are lots of factors 9 which could affect the efficiency of supply chain, like organization structure, channel of information, geographical distribution, industry characteristics etc., the bullwhip effect is still one of the most deep-rooted influence factor for the whole system. You cannot find another such kind of element like the bullwhip effect which could affect all parts of the whole supply chain system. No matter what kind of industry the firm are, what place does the firm in or how hard does the firm try by its own, the processes inside of the firm from producing plan to all kind of inventory must be all influenced by the bullwhip effect and hard to avoid. That is why the bullwhip effect is one of the most deep-rooted influence factor.
QUESTION 1 (A) Discuss the term “bullwhip effect” and its causes.
The bullwhip effect is a distribution channel phenomenon in which forecasts yield supply chain inefficiencies. It refers to increasing swings in inventory in response to shifts in customer demand as you move further up the supply chain. The concept first appeared in Jay Forrester's Industrial Dynamics (1961) and thus it is also known as the Forrester effect. The bullwhip effect was named for the way the amplitude of a whip increases down its length. The further from the originating signal, the greater the distortion of the wave pattern. (July 2013) The bullwhip effect on the supply chain occurs when changes in

...Part 1. Report to Danny Wilco To: Danny Wilco From: Kay Smith Subject: Re: Ordering product for EBBD from the Kentucky Hooch and Beer Company Background: Our efforts to increase sales of Kentucky Swamp Brew, for our college aged customers, Brew received mixed support from area retailers. For example, our advertising campaign was initially productive, we received a 75% increase in retail orders for three continuous weeks (the duration of the advertising campaign). However, retail orders dropped off 20% when the advertising campaign ended. We appeared to have limited insight on customer interest in Kentucky Swamp Brew and we also failed to properly coordinate with the brewery so they can have supplies on hand to meet projected and actual retail orders. Strategy: For product ordering, I employed a three phase strategy. The first phase was to order more products from KHBC Brewery then current retail order level so we would have inventory on hand to support increased orders, when the advertising efforts took effect. The second phase was to order products based on increased retail order level while adjusting the final order to compensate for brewery delivery in efficiencies. The third phase, towards the end of the Kentucky Swamp Brew sales campaign was to adjust ordering so excess inventory would be controlled. Results: From the attached excel product you will see that our ordering strategy was effective as we were able to stay up with customer demands, compensate...

Bull Whip Case

...A bullwhip consists of a handle section, a thong, a fall, and a cracker. A wrist loop may also be present, although its chief purpose is for hanging one's whip on a hook. Aesthetically, it finishes the handle. The main portion of the bullwhip's length is made up of a braided body or thong. Made of many strips of leather, the number of braids or plaits is an important factor in the construction of the whip. Often the thong is multi-layered, having one or more "bellies" in the center. Quality whips have at least two bellies, made of braided leather like the surface of the whip, though with fewer plaits. Lower-quality whips may have no bellies at all, and are sometimes stuffed with materials such as newspaper which will break down with use. Unlike in the Australian stock whip, the thong connects in line with the handle (rather than with a joint), or sometimes completely covers the handle. The handle is usually short, being between 8 and 12 inches long. While some whips have an exposed wooden grip, others have an intricately braided leather covered handle. Leather-covered handles usually contain a butt foundation, which is held in the palm of the hand when cracking, and can have a wrist loop, used for hanging the whip at the end of the day, not for putting around the wrist during use. Some handles swivel, making it easier to do certain types of unsophisticated cracks but making it harder to do others, or to use the whip for any type of accurate targeting. The Australians introduced...
