摘要
提出了一个具有时滞的SIR计算机网络病毒传播模型。以杀毒软件清理网络病毒所花费的时间周期时滞为变量,通过讨论模型特征方程的根的分布,研究了模型的局部稳定性和Hopf分支的存在性,并利用数值模拟证明了分析的理论结果。
A time-delay SIR computer network virus transmission model is presented.By regarding the time delay due to anti-virus software removing viruses as a bifurcation parameter,local stability of the model and the existence of Hopf bifurcation are studied.Finally,numerical simulations have been given to prove the analysis of the theory.
