这篇论文的目的是研究接种疫苗对计算机病毒传播的影响。为此，提出了一种新的计算机病毒传播模型，其中包括一个非线性疫苗接种概率。对该模型的定性分析表明，依赖于基本再生数的值，无病毒平衡点或病毒平衡点是全局渐近稳定的。仿真实验的结果不仅验证了模型的有效性，也表明了非线性疫苗接种策略的有效性。通过参数分析，提出了一些有效的病毒清除策略。(c)2013爱思唯尔有限公司版权所有。
This paper is intended to examine the effect of vaccination on the spread of computer viruses. For that purpose, a novel computer virus propagation model, which incorporates a nonlinear vaccination probability, is proposed. A qualitative analysis of this model reveals that, depending on the value of the basic reproduction number, either the virus-free equilibrium or the viral equilibrium is globally asymptotically stable. The results of simulation experiments not only demonstrate the validity of our model, but also show the effectiveness of nonlinear vaccination strategies. Through parameter analysis, some effective strategies for eradicating viruses are suggested. (c) 2013 Elsevier B.V. All rights reserved.
