The research aims to explore how differences in populations and their interactions affect infectious disease transmission dynamics.
Developed a community-based SIR compartmental model for multiple populations.
Incorporated multidimensional parameters like contact preferences and varying transmission rates.
Used agent-based simulations and multi-scenario experiments to analyze network structure and interactions.
Applied early COVID-19 data for parameter fitting and model validation.
Coupling of service populations significantly accelerates epidemic transmission.
Population migration impacts infection spread in a non-monotonic way.
Improving recovery rates in small service populations can reduce the final epidemic size in larger populations.
High accuracy observed in model predictions compared to empirical data.
