The negative consequences, such as healthy and environmental issues, brought by rapid urbanization and interactive human activities result in increasing social uncertainties, unreliable predictions, and poor management decisions. For instance, the Coronavirus Disease (COVID-19) occurred in 2019 has been plaguing many countries. Aiming at controlling the spread of COVID-19, countries around the world have adopted various mitigation and suppression strategies. However, how to comprehensively eva luate different mitigation strategies remains unexplored. To this end, based on the Artificial societies, Computational experiments, Parallel execution (ACP) approach, we proposed a system model, which clarifies the process to collect the necessary data and conduct large-scale computational experiments to evaluate the effectiveness of different mitigation strategies. Specifically, we established an artificial society of Wuhan city through geo-environment modeling, population modeling, contact behavior modeling, disease spread modeling and mitigation strategy modeling. Moreover, we established an evaluation model in terms of the control effects and economic costs of the mitigation strategy. With respect to the control effects, it is directly reflected by indicators such as the cumulative number of diseases and deaths, while the relationship between mitigation strategies and economic costs is built based on the CO emission. Finally, large-scale simulation experiments are conducted to evaluate the mitigation strategies of six countries. The results reveal that the more strict mitigation strategies achieve better control effects and less economic costs.
快速城市化和人类互动活动带来的负面后果,如健康和环境问题,导致社会不确定性增加、预测不可靠以及管理决策不佳。例如,2019年出现的冠状病毒病(COVID-19)一直在困扰许多国家。为了控制COVID-19的传播,世界各国采取了各种缓解和抑制策略。然而,如何全面评估不同的缓解策略仍未得到探索。为此,基于人工社会、计算实验、平行执行(ACP)方法,我们提出了一个系统模型,该模型阐明了收集必要数据并进行大规模计算实验以评估不同缓解策略有效性的过程。具体而言,我们通过地理环境建模、人口建模、接触行为建模、疾病传播建模和缓解策略建模建立了武汉市的人工社会。此外,我们从缓解策略的控制效果和经济成本方面建立了一个评估模型。关于控制效果,它直接由疾病累计数量和死亡人数等指标反映,而缓解策略与经济成本之间的关系是基于碳排放建立的。最后,进行大规模模拟实验以评估六个国家的缓解策略。结果表明,越严格的缓解策略能取得更好的控制效果和更低的经济成本。
