摘要
通过分析以前模型的不足,结合现实情况,参考生物数学中的传染病模型,提出了一种有反病毒措施的计算机病毒传播时滞模型。通过同以往模型的数值解比较,发现本模型更能反映实际网络中病毒的传播情况,通过本模型能更好地理解和预测现实计算机网络中病毒传播的规模与速度。
By analyzing the deficiency of the model in the past,combining the reality and consulting the infectious disease model in biomathematics,this paper puts forward a new model with time delay of computer virus propagation in the network with antivirus measure. The numerical solution of the new model matches the real situation of the virus propagation in the network better than that of the model in the past. This model leads to a better understanding and prediction of the scale and speed of virus spreading.
