摘要: 考虑了一类受接种疫苗影响的带时变时滞的SVEIR疾病传播模型,针对不同取值下的病毒基本再生数R0,分别采取Liapunov函数法和Routh-Hurwitz判别法对模型平衡点的存在性、稳定性、分岔性进行研究。最后对不同的R0进行数值模拟,验证理论分析结果的正确性。
Abstract: In this paper, we consider a SVEIR disease transmission model with time-varying delay affected by vaccination, for the basic regeneration number of virus R0 under different values, Liapunov func-tion method and Routh-Hurwitz criterion were used to study the existence, stability and bifurcation of model equilibrium points. Finally, the numerical simulation of different R0 is carried out to verify the correctness of theoretical analysis results.
