我们研究了连续意见和离散行动（CODA）的代理商采用新产品的动态。该模型是这样的，在采用一个新的想法或产品的拒绝越来越多的加权邻居代理作为证据对产品。在这些规则下，我们研究了收养次数的分布和收养者在人口中的最终比例。我们比较的情况下，最初的采用者聚集的情况下，他们是随机分散在社会网络和调查小世界的影响，采用者的最终比例。该模型预测了一个厚尾分布的后采用者，这是由经验数据验证。(C)2009爱思唯尔有限公司版权所有。
We study the dynamics of the adoption of new products by agents with continuous opinions and discrete actions (CODA). The model is such that the refusal in adopting a new idea or product is increasingly weighted by neighbor agents as evidence against the product. Under these rules, we study the distribution of adoption times and the final proportion of adopters in the population. We compare the cases where initial adopters are clustered to the case where they are randomly scattered around the social network and investigate small world effects on the final proportion of adopters. The model predicts a fat tailed distribution for late adopters which is verified by empirical data. (C) 2009 Elsevier B.V. All rights reserved.
