The main contents of the dissertation are to reengineer business process based on bpr theory , study the forecast method of logistic requirement of multi - varieties and small - batch product distribution , and construct the distribution system fitting distribution business process based on internet 论文首先分析了多品种小批量产品分销中的两个主要问题：长鞭效应、物流需求预测不准，并对相关的营销特点及物流配送特征进行了总结。
As scm is often affected by the production and inventory strategy , information distortion appears in it . because of these information distortions , the demand order variabilities in the supply chain are amplified as they move up the supply chain even when the downstream consumer sales do not vary much 但是由于供应链常常受到企业生产策略以及存货政策的影响，以致造成链上的信息扭曲，进而产生“长鞭效应” （ bullwhipeffect ） 。
One is bullwhip effect amplifying , distorting and delaying market information which is transferred up distribution network . another is inexact forecast of logistic requirement . furthermore , it concludes the sale or logistic characters of multi - product and small - batch production enterprise 长鞭效应的存在，导致市场信息在沿着分销网络逐级上传的过程中出现放大、扭曲、迟滞现象，严重影响了企业的市场响应速度，增加了企业生产、库存、销售成本和风险。
Thirdly , we have a deep research on how the organization structure , information structure and decision structure of supply chain affect the bullwhip effect , and we establish a multi - stages inventory control system model of the supply chain to study the effect further by computer simulation 三、分别从供应链的组织结构、信息结构和决策结构三个方面，深入分析供应链结构对长鞭效应的影响。四、建立供应链的多级库存控制系统模型，用计算机仿真的方法进一步分析供应链结构对长鞭效应的影响。
And round the corner came the huntsman and whipper - in , danilo , a grey , wrinkled man , with his hair cropped round in the ukrainian fashion . he held a bent whip in his hand , and his face had that expression of independence and scorn for everything in the world , which is only to be seen in huntsmen 猎犬训练管理人和狩猎长丹尼洛从墙角走出来了，他头发苍白，满面皱纹，剪了个乌克兰式的童化头，手里执着一根短柄长鞭，流露出一副唯独猎人才有的独立活动和蔑视尘世中一切的表情。
Then , target the " bullwhip effect " problem , this dissertation proposed a method . by reengineering the distribution business process , separation of commercial circulation and substance circulation and reduction network level , the bullwhip effect can be significantly weaken and enhance enterprise market response capability and customer server level 通过对销售业务流程进行重组，将企业商流、物流分开，减少分销网络层次，有效地弱化了“长鞭效应” ，提高了企业市场响应能力和客户服务水平。
Next , mathematical models concerning the bullwhip effect are set up to analyze this effect . models presented here reveal how the lead time , frequency of demand forecast and the price fluctuation affect the bullwhip effect and prove that information sharing can mitigate the bullwhip effect . in addition , a variety of corrective actions are recommended to reduce the bullwhip effect and improve the efficiency of supply chain management 接下来，用定量的方法建立起了相应的数学模型对“长鞭效应”进行了深入分析，揭示了订货提前期、企业需求预测频率的变化以及价格波动对长鞭效应的影响，并且证明了供应链的信息共享可以弱化“长鞭效应” 。
Based on the analysis of the supply chain ' s infrastructure , the existence of the bullwhip effect is discussed . the actual play of the computerized beer game has also been used to show how the bullwhip effect occurs . furthermore , the harmfulness of the bullwhip effect is surveyed and presented 首先从分析供应链的结构出发，研究了“长鞭效应”是怎样产生的，并且通过对电脑化啤酒游戏（ computerizedbeergame ）的实际操作，从游戏过程及其结果再现了长鞭效应的产生。
