Agent-based Simulation for Epidemics Transmission in Social Contact Networks

摘要

Agent-based modeling and simulation is applied to simulate the real social phenomenon nowadays.In this paper, a kind of contact network with different strength of ties has been built based on the NW small-world network.Epidemics transmission experiments are executed according to the virus transmission model SIR. The simulation shows how epidemics spread in different percents vaccinated people and in different policy to restrict action of people. The results show that the vaccine therapy can only protect the inoculators if we do nothing to control human's action and the protection increases as the number of inoculators increases.If we want to stop the epidemics spreading in a very short time the vaccine therapy should be combined with the human action restriction.
