SoepSim - Improving agent-based modeling by utilizing large-scale survey data

IRIS and SimTech

Collaborative Research Project

Project Focus

The transmission of infectious diseases depends on human behavior and their relations. However, current epidemiological models consider social structures only at a highly abstract level. To increase the predictive capability and explanatory power, models of human behavior incorporating social complexity are therefore urgently needed. We address this gap by developing an agent-based approach that utilizes comprehensive micro-level data of complete households. This allows us to create artificial societies that are representative for underlying social structures and contact networks. Based on comprehensive COVID-19 data, we then utilize Bayesian model calibration to estimate unknown parameters and quantify their uncertainty. Conducting various simulation experiments will then allow us to identify super-spreaders and assess the efficiency of interventions. Thus, the project makes not only a substantial contribution to a holistic ”Digital Human Model”, but is also a methodological response to the increasing demand for empirically-calibrated simulation models. However, computational models always bear the risk of incorporating biases. We will tackle this challenge, which is enhanced by potential stigmatization of super-spreaders, by incorporating sensitivity analyses and so pave the way for the development of systematic ”methods of reflection”.
