利用流动性数据设计COVID-19大流行的最佳封锁策略

Using mobility data in the design of optimal lockdown strategies for the COVID-19 pandemic

Ritabrata Dutta, Susana Gomes, Dante Kalise, Lorenzo Pacchiardi

摘要:

提出了一个新冠肺炎疫情传播的数学模型,该模型将年龄结构的易感-暴露-死亡动态与考虑人口流动性的真实手机数据相结合。通过近似贝叶斯计算进行动态模型调整。基于非线性模型预测控制确定最佳封锁和退出策略,并限制公共卫生和社会经济因素。通过广泛的计算验证的方法,它表明,它是可以计算出强大的退出战略与现实的减少流动性值,以告知公共政策的制定,我们使用来自英国和法国的数据集验证的方法的适用性。实现所描述的实验的代码可在https://github.com/OptimalLockdown获得。

英文摘要:

A mathematical model for the COVID-19 pandemic spread, which integrates age-structured Susceptible-Exposed-Infected-Recovered-Deceased dynamics with real mobile phone data accounting for the population mobility, is presented. The dynamical model adjustment is performed via Approximate Bayesian Computation. Optimal lockdown and exit strategies are determined based on nonlinear model predictive control, constrained to public-health and socio-economic factors. Through an extensive computational validation of the methodology, it is shown that it is possible to compute robust exit strategies with realistic reduced mobility values to inform public policy making, and we exemplify the applicability of the methodology using datasets from England and France. Code implementing the described experiments is available at https://github.com/OptimalLockdown.
