意识和运动与流行病的传播-分析城市社会/技术网络的动态模型

Awareness and Movement vs. the Spread of Epidemics - Analyzing a Dynamic Model for Urban Social/Technological Networks

Robert Elsässer, Adrian Ogierman

摘要:

我们考虑流行病在技术和社交网络中的传播。人们的反应如何?意识和谨慎的行为有帮助吗?我们分析了这些问题,并提出了一个动态模型来描述个人和/或他们的移动设备在一定的(理想化的)城市环境中的运动。此外,我们的模型还考虑到不同的地点可以容纳不同数量的人(可能是他们的移动设备),他们可能会相互传播感染。我们得到两个主要结果。首先,我们证明w.r.t.我们的模型至少一小部分系统将保持不受感染,即使不采取对策。第二个结果表明,使用某些只影响个人行为的对抗措施,可以避免流行病的流行。研究结果解释了疾病的可能过程,并指出了为什么具有成本效益的对策可能会将总感染人数从人口的高百分比减少到可以忽略不计的比例。

英文摘要:

We consider the spread of epidemics in technological and social networks. How do people react? Does awareness and cautious behavior help? We analyze these questions and present a dynamic model to describe the movement of individuals and/or their mobile devices in a certain (idealistic) urban environment. Furthermore, our model incorporates the fact that different locations can accommodate a different number of people (possibly with their mobile devices), who may pass the infection to each other. We obtain two main results. First, we prove that w.r.t. our model at least a small part of the system will remain uninfected even if no countermeasures are taken. The second result shows that with certain counteractions in use, which only influence the individuals' behavior, a prevalent epidemic can be avoided. The results explain possible courses of a disease, and point out why cost-efficient countermeasures may reduce the number of total infections from a high percentage of the population to a negligible fraction.
