This work addresses the spread of a disease within an urban system, defined as a network of interconnected cities. The first step consists of comparing two different approaches: a macroscopic one, based on a system of coupled Ordinary Differential Equations (ODE) Susceptible-Infected-Recovered (SIR) systems exploiting populations on nodes and...

A hybrid model coupling an aggregated equation-based model and an agent-based model is presented in this article. It is applied to the simulation of a disease spread in a city network. We focus here on the evaluation of our hybrid model by comparing it with a simple aggregated model. We progressively introduce heterogeneities ...

Dans cet article, nous nous intéressons à la diffusion de maladies dans un réseau. Nous comparons deux approches, l'une macroscopique (métapopulationnelle) et l'autre hybride, couplant des systèmes dynamiques de type EDO sur les nœuds et des agents sur les arêtes Nous reproduisons le même pic d'intensité de l'épidémie (Imax) avec ces deux...
