Abstract: Bullwhip effect is inherent in the supply chain system，and it is impossible to eliminate completely，but its risk can be controlled by exploring a lot of effective ways.In this paper，wavelet transform technology is used to deal with the “Burr” （Noise） of bullwhip effect nominal cycle，and the part of high-frequency is filtered，the details of wave crest and trough are retained.All of these can provide a reference for the decision-making of bullwhip effect control and supply chain management.

Key words: wavelet transform, bullwhip effect, de-noising, supply chain

摘要： 牛鞭效应是供应链系统中固有的，想彻底消除不太可能，但可以探索一些有效的方法对其带来的风险进行有效控制。利用小波变换技术，对牛鞭效应名义周期中的“毛刺”（噪声）进行处理，滤除了信息中的高频部份，保留了信息的波峰与波谷细节，为牛鞭效应的控制和供应链的管理提供了决策参考。
