Abstract
In this paper, the effects of the global influence with random element are examined. We consider two types of agents, pioneers and followers, in a two-dimensional grid world. Agents decide their attitudes by local influences (effects of the neighbors) and global influences (effects of mass-medias), then change their attitudes. So as to consider the variance of effects which global influences give agents, we propose the global influence with a random element. Simulation studies show that the results of agent-based simulations are very sensitive to the global influence including the random effect.
