| 摘 要： | 提出了一个元胞自动机扩展模型,研究HIV/AIDS在人群中传播扩散的动态过程.将个体在感染后的艾滋病(AIDS)发病过程划分成几个子阶段,以方便研究个体行为对传播扩散过程的影响.为了准确地描述传播过程,将个体异质性引入个体的行为中,并扩展了邻域概念.仿真结果表明,在异质性条件下,人群数量、初始感染率、个体活跃程度,以及邻域形式对HIV/AlDS传播扩散行为有重要的影响.

| Abstract: | In this paper,we develop an extended CA simulation model in studying the dynamical behaviors of HIV/AIDS transmission.The model explicitly models the post-infection process of AIDS disease,facilitating the study of the effects of agents' behaviors on the dynamics of transmission.In order to better describe the dynamics of HIV/AIDS transmission among population,this paper introduces the heterogeneity into agents' behaviors,and extends the definition of neighborhood.The simulation results show the factors suc... |
