Abstract
In this study, we performed a simulation of the EC by using a multi-agent model .
In recent years , the development of SNS, promotes the information propagation , impact remark individuals are becoming larger .
Among these , on the consumer of the web , to predict the opaque purchasing behavior is believed to be important for management .
Multi-agent model is by the interaction of individual behavior can represent a macro phenomenon . Also By scenario analysis ,
EC can be used to predict consumer behavior on the site , it is expected to lead to support decision makers .
