Abstract

This model comparison quantifies the difference between the results of a population model, using ordinary differential equations, and an inhomogeneous spatial approach, using a lattice gas cellular automaton. Both approaches describe a classical SIR-epidemic. The system definition of the epidemic, model specification and parameter identification were already formulated by Miksch et al [1]. For the sake of quantifyable comparisons a norm was introduced. The tasks from the revised ARGESIM Comparison 17 [1] were completed and the results were analysed and visualised. Every result was interpreted according to the knowledge of the modelling approaches and the setup of the experiment at hand.
