从流行病到大流行病模型

From Epidemic to Pandemic Modelling

Shannon Connolly, David Gilbert, Monika Heiner

摘要:

我们提出了一种方法,系统地扩展流行病模型的多级和多尺度的时空流行病。我们的方法建立在使用有色随机和连续Petri网促进健全的组件为基础的扩展基本SIR模型,包括人口分层和空间地理信息和旅游连接,表示为图形,从而在强大的分层流行病集合种群模型。这种方法本质上易于使用,产生可扩展和可重用的模型,具有高度的清晰度和可访问性,可以在确定性或随机范式中阅读。我们的方法由一个公开的平台PetriNuts支持;它可以可视化构建和编辑模型;确定性,随机性和混合模拟以及结构和行为分析。所有的模型都可作为补充材料,以确保可重复性。

英文摘要:

We present a methodology for systematically extending epidemic models to multilevel and multiscale spatio-temporal pandemic ones. Our approach builds on the use of coloured stochastic and continuous Petri nets facilitating the sound component-based extension of basic SIR models to include population stratification and also spatio-geographic information and travel connections, represented as graphs, resulting in robust stratified pandemic metapopulation models. This method is inherently easy to use, producing scalable and reusable models with a high degree of clarity and accessibility which can be read either in a deterministic or stochastic paradigm. Our method is supported by a publicly available platform PetriNuts; it enables the visual construction and editing of models; deterministic, stochastic and hybrid simulation as well as structural and behavioural analysis. All the models are available as supplementary material, ensuring reproducibility.
