提出了一个agent动态小世界网络仿真模型,结合了小世界网络结点和agent的双重特性,研究了HIV(Human Immunodeficiency Virus)在同性人群中传播扩散的动态过程。为了适应社会网络上HIV传播的动态特性,模型在小世界网络基础上增加两个个体之间的偶然关系和固定关系以及个体从系统中的移入和移出。介绍了HIV病情发展的不同阶段及疾病参数,考虑了个体的自主性和检测对HIV传播的影响。仿真结果表明该模型较好地反映了动态社会网络和个体自主性行为对HIV传播的影响。
An agent dynamic small-world network simulation model is proposed. Combining with the dual characteristics of small-world network nodes and agents, the dynamic process of HIV (Human Immunodeficiency Virus) spreading and spreading in the same-sex population is studied. In order to adapt to the dynamic characteristics of HIV transmission on social networks, the model increases the contingency and fixed relationship between two individuals on the basis of the small-world network and the individual’s movement in and out of the system. The different stages of HIV disease progression and disease parameters are introduced, taking into account individual autonomy and the impact of testing on HIV transmission. The simulation results show that the model better reflects the influence of dynamic social networks and individual autonomous behaviors on HIV transmission.
