In this paper, a SIRS epidemic model with immunization on sparsely distributed regular lattice is proposed. Based on the model, we research the effects of immunized rate, crowd-density, spread efficiency and moving activity of agents on disease spread. The theoretical analysis and analog simulation indicate that immunization can increase the spreading threshold. Besides, there is a critical threshold...
A local area control SIS model based on 2 dimension regular network is proposed. The process of virus spreading is studied in 2 dimension regular network under local area control. The research suggests that with the span of local area control increases, the stable infected proportion to reduce. The theoretical analysis and analog simulation shows that there is a critical value in the model. Only when...
