A Research On The Mechanism And Countermeasure Of The Bullwhip Effect Under The SCM Mode

In SCM, it often exists such as phenomena: because it is inaccurate to predict, the demand is indeterminate , supply is unstable , enterprise person who cooperate lack , produce and transport with harmony supply that lead to the fact such as being bad homework unbalanced , stock remain high , cost pass high. The origin of causing these questions has a lot of, but one of the main reasons is the Bullwhip Effect. The Bullwhip Effect supplies a kind of demand on the chain and makes a variation and enlarges (variance is enlarged) the phenomenon, it is the information flow while transmitting from final customer end to the primitive supplier's end, it is unable to realize the sharing of information effectively, make information twist and amplify step by step , has caused demand information to present greater and greater fluctuation situation. The information amplify situation one of picture get rid of blow catch Bullwhip Effect very on graphical display because of twisting, called the Bullwhip Effect vividly. The customer end of the low reaches is equivalent to the root of the whip the most, and the end of supplier of the upper reaches is equivalent to the tip department of the whip the most, one of department's end have one shaking slight in root, transmit to tip end can appear heavy fluctuation very. In supplying the chain, change the more largely this kind of effect to the upper reaches, it is the farther from the terminal customer, the greater influence is. Bullwhip Effect is it supply demand of chain information distorted and distorted degree amplify step by step to make, it is obvious that it is endangered: 1.The direct consequence of the Bullwhip Effect is stocks. 2.The excessive demand change aggravates enterprise's production schedule change, causes the extra costs to increase by 3. The Bullwhip Effect is apt to cause the illusion that the demand increase, make the production capacity that manufacturers design greater than the real demand 4. Customer's demand can't be satisfied in time, the service level is bad.It causes the heavy losses which supplies the efficiency of the chain to supplythe Bullwhip Effect problem in the chain, but the Bullwhip Effect is by the built-in property that the structure of supplying the chain itself is determined, it is unable to totally eliminated. So weaken the influence of the Bullwhip Effect and become and improve and supply the efficiency of the chain entirely to the maximum extent, realize supplying the key to the management objectives of the chain. The research of the Bullwhip Effect has great theory and practice meaning. The thesis has announced the mechanism that the Bullwhip Effect produces , sum up the main reason that the Bullwhip Effect produces as requirement forecasting method , shortage playing chess , one ahead of time of order , batch of the order and price fluctuate , information transmit the obstacle, then how Bullwhip Effect negative effect of maximum reducing puts forward the concrete measure, as follows, mainly 1. Adopt the supplier to manage the mode 2 held in store. Make incentive measure and goal keep unanimous 3. Improve accuracy 4 of information. Improve 5 achievements of running and design 6 in order to stabilize the scale of order tactics of fixed price. Construct partnership relation and believe in the mechanism. The Bullwhip Effect to supply chain management realize supply chain profit maximize main obstacle factor of goal while being whole of, we can take certain measure and utilize the information technology to alleviate the negative effect that the Bullwhip Effect cause maximumly , however, there must be a prerequisite in this, that is to visit and can establish close partnership relation among enterprises from head to foot, because only in supply and demand both sides trust each other, on the foundations of the benefits-sharing and shared risks, business datum that it could discloses to be one's own enterprise, business course and Share information; Only on the premise of supplying chain every enterprise and reaching this kind of partnership too, utilize the advanced information technology and information management system, could solve the influence of different factors effectively , alleviate the Bullwhip Effect to the maximum extent. This whether innovation of thesis emphasize in is it is it supply with enterprise of chain construct one partnership relation and believe in mechanism to enter to join promptly too.
