Uncertainty about the supply chain and its various components causes demand variability in the length of chain in a way that as diverting from the final customer demand and actual orders, more fluctuation in amount of orders is observed and this can be followed by undesirable effects. This phenomenon is called Bullwhip effect. Several factors are involved in the occurrence of this problem for which some strategies to are listed. In this paper, first Bullwhip effect and what caused it in the supply chain are defined. Then, Key factors in reducing the effects in Auto industry using Survey are analyzed. Finally, with regard to the capabilities of electronic business, its role in confronting this phenomenon will be expressed. This Research is an Applied Research and a questionnaire containing 26 questions was used for the analysis. According to various aspects of creating Bullwhip Effect, partial sampling was used and a collection of experts in the field of inventory control, production planning and parts supply, sales, after sales service and supply chain management were surveyed. Calculated Samples are 171 experts. In this paper, The Mean Test is used to evaluate each hypothesis and finally Friedman's Test is used to assess being equal rank of Reducing Factors of Bullwhip effect. Innovative aspect of the research is observed in the study and identification of key factors in creating Bullwhip effect in supply chain and investigation of electronic business impact in reducing the negative effect.
