基于元胞自动机的个体移动异质性传染病传播模型
CA-based epidemic propagation model with inhomogeneity and mobility
摘要
Abstract
An epidemic SEIR model with inhomogeneity and mobility is built based on the theory of cellular automata . The inhomogeneity in individuals′ behaviors is considered by assigning varying levels of infectivity and susceptibility .The distance of population movement will be limited and the percentage of population movement has been realized ,so random walk cellular automata is extended . The proposed model can be served as a basis to simulate real epidemics based on real data .According to the real data about influenza A (H1N1) ,the numerical simulation is realized .The results of simulation are very close to the practical data announced by the official .It is show n that the model is rational and valid . Further study is conducted on the effect of population movement on epidemic propagation .Compared with the max-distance of population movement ,the effect of the percentage of population movement is more sensitive ,and it can accelerate the spreading of the epidemic disease .关键词
