Research on Epidemic News Spread Based on Multi-Agent Simulation

A multi-agent simulation model of epidemic news spread (ENS) was designed and realized and the impacts of the number of personal social ties,the belief degree to epidemic news and the spread network structure to the epidemic news spread process were studied.It is found that with increasing number of social ties,the spread speed of epidemic news will speed up rapidly and decreases the ratio of the number of the people heard of epidemic news directly;while with the increasing degree of the trust to the epidemic news,the spread speed of epidemic news will also speed up rapidly,but variation of the ratio of the number of the people heard of epidemic news directly is not significant.It is also found that the forgetting speed and the spread speed becomes slower than that in random network when the spread network structure is assumed as small network.
