数据驱动的分布式减灾策略与突变流行病过程分析

Data-Driven Distributed Mitigation Strategies and Analysis of Mutating Epidemic Processes

Philip E Pare, Sebin Gracy, Henrik Sandberg, Karl Henrik Johansson

摘要:

本文研究了一个离散时间SIS模型,其中感染和愈合参数以及底层网络可能随时间变化。我们提供的条件,该模型是良好的定义,并研究其稳定性。对于对称图上具有齐次感染率的系统,我们给出了健康状态(即病毒被根除的状态)的全局指数稳定性(GES)的充分条件。对于有向图上分布有异质病毒的系统,在病毒变化不太快的条件下,建立了健康状态GES的一个充分条件。

英文摘要:

In this paper we study a discrete-time SIS (susceptible-infected-susceptible) model, where the infection and healing parameters and the underlying network may change over time. We provide conditions for the model to be well-defined and study its stability. For systems with homogeneous infection rates over symmetric graphs,we provide a sufficient condition for global exponential stability (GES) of the healthy state, that is, where the virus is eradicated. For systems with heterogeneous virus spread over directed graphs, provided that the variation is not too fast, a sufficient condition for GES of the healthy state is established.
