我们描述了一个通用的框架,在现实的动态社交网络,其中包括异质性的类型的个人,类型的相互连接的风险承担的关系,并通过它们传播的病原体的流行病的建模和随机模拟。动态支持通过到达和离开过程,风险关系的持续重组,以及病原体传染性的变化,由自然历史的规定;动态通过对单个节点的本地代理及其风险行为的约束进行调节,而模拟轨迹使用系统范围的指标进行验证。为了说明其效用,我们提出了一个案例研究,适用于模拟艾滋病毒的静脉注射毒品使用者(IDUs)的人工网络中使用的社会因素对艾滋病毒风险调查收集的数据建模的建议框架。
We describe a general framework for modeling and stochastic simulation of epidemics in realistic dynamic social networks, which incorporates heterogeneity in the types of individuals, types of interconnecting risk-bearing relationships, and types of pathogens transmitted across them. Dynamism is supported through arrival and departure processes, continuous restructuring of risk relationships, and changes to pathogen infectiousness, as mandated by natural history; dynamism is regulated through constraints on the local agency of individual nodes and their risk behaviors, while simulation trajectories are validated using system-wide metrics. To illustrate its utility, we present a case study that applies the proposed framework towards a simulation of HIV in artificial networks of intravenous drug users (IDUs) modeled using data collected in the Social Factors for HIV Risk survey.
