考虑了个体的异质性、移动性和个体间的有效接触传染概率,提出了基于元胞自动机带有隔离干预的传染病仿真建模方法。扩展了传统的Moore邻域,模拟仿真了不同的染病停留时间和隔离力度对传染病传播的影响。仿真结果与采用隔离干预对传染病传播的宏观特征相吻合。研究表明:对已感染的患者,染病停留时间越短,采取隔离措施的力度越大,对传染病传播的抑制作用越显著。可为政府和相关部门对传染病制定有效的遏制措施提供理论支持。
攷慮瞭箇體的異質性、移動性和箇體間的有效接觸傳染概率,提齣瞭基于元胞自動機帶有隔離榦預的傳染病倣真建模方法。擴展瞭傳統的Moore鄰域,模擬倣真瞭不同的染病停留時間和隔離力度對傳染病傳播的影響。倣真結果與採用隔離榦預對傳染病傳播的宏觀特徵相吻閤。研究錶明:對已感染的患者,染病停留時間越短,採取隔離措施的力度越大,對傳染病傳播的抑製作用越顯著。可為政府和相關部門對傳染病製定有效的遏製措施提供理論支持。

The paper is considering the individual heterogeneity, mobility and the effective infection probability between individuals; it is proposed that a simulation model with isolation intervention based on cellular automata. The classical Moore neighborhood is extended to simulate the effect of different disease duration and isolated intensity, and the simulation result is coincidence with the macroscopic characteristics of epidemic controlled by isolation intervention. Researches show that to the infected, the smaller of disease duration, the greater of isolation intensity, and the more significant inhibition on the spread of epidemic will be, which can provide powerful theoretical support for the government and relevant departments to prevent and control the spread of epidemic more effectively, too.
