企业网络中快速的点对组信息共享过程也会使信息暴露在更严重的病毒攻击之下。另一方面,相对大量的病毒攻击可能会对网络终端用户造成心理抑制的影响。提出了e-Seir模型的非线性感染力函数,用于研究网络病毒流行中的拥挤和心理效应。通过对无病毒平衡点和地方病平衡点的全局稳定性分析,揭示了拥挤和心理效应对网络病毒传播过程的影响。此外,分析和仿真结果也为信息共享网络中的反病毒实践提供了一些管理上的见解。
The fast point-to-group information sharing process within an enterprise network also exposes information to more severe virus attacks. On the other hand, a relative large number of virus attacks may result in psychological effects of inhibition for the network end-users. In this paper, a nonlinear force of infection function for e-SEIR model is presented to study the crowding and psychological effects in network virus prevalence. By carrying out a global analysis of the stability of both the virus-free and endemic equilibrium, this work reveals how the crowding and psychological effects have impacts on network virus propagation process. Furthermore, analysis and simulation results show some managerial insights that are helpful for the practice of antivirus in information sharing networks.
