摘要: 同时考虑了脉冲接种、脉冲剔除和隔离策略,建立了一个SIQR传染病模型,从理论分析和数值模拟方面研究了SIQR传染病模型的动力学性质.首先,得到了模型的无病周期T解的存在性和基本再生数R0; 其次,应用Floquet定理证明了无病周期T解的局部渐近稳定性和利用脉冲微分不等式证明了其全局渐近稳定性;接着,进行了计算机数值模拟来进一步验证理论结果的正确性.最后,通过对基本再生数R0及其偏导数,分析了脉冲接种、脉冲剔除和隔离这些预防和控制策略对传染病流行的影响.

Abstract: Impulsive vaccination, impulsive elimination and quarantine strategies were considered in an SIQR epidemic model. The dynamical behavior of an SIQR epidemic model was discussed both theoretically and numerically. Firstly, the disease-free T periodic solution and the basic reproductive number R0 were obtained. Secondly, the local asymptotic stability of the disease-free T periodic solution with Floquet theorem was proved and the global asymptotic stability of the disease-free T periodic solution was also proved by impulsive differential equation. Thirdly, numerical simulation was conducted to illustrate the

Key words: epidemic model, basic reproductive number, global stability, impulsive differential equation, impulsive vaccination, impulsive elimination
