Research on diffusion of warning based on multi-agent modeling

Quick and highly efficient warning is critical in any emergency evacuation. From the issuing of warning until action taken by people in response, the entire course is a very complex process which is restrained by social, economic, population and other factors. To study the diffusion characteristics of warning in the social network environment as well as the relevant influencing factors, under the guidance of complex system theory and multi-agent modeling method, this paper analyzes the six stages in the diffusion process of warning and builds a diffusion model of warning on the multi-agent software platform Repast based on WS small world network model. Through the study of the simulation results, we find that the diffusion of warning is similar to the diffusion of other information, which showed a similar S-curve.
