The growing body of knowledge on agent-based modeling (ABM) points to statistical and systematic uncertainty as the most challenging obstacles to developing parsimonious models. To decrease ABM dimensionality, a comprehensive uncertainty analysis (UA) and sensitivity analysis (SA) are employed, where input uncertainty is propagated through the model using Monte Carlo simulations, resulting in probability distributions (PDs) of outputs. The PDs are further summarized using variance—a simple yet succinct measure of result variability. The variance is apportioned to model inputs using decomposition, in order to quantify which of them and to what extent affect the variability of ABM results. The calculated sensitivity indices represent fractional contributions of each input to output variance. To simplify the model, inputs with low sensitivity values can be set to constants (e.g. mean), effectively decreasing model input space.
