A procedure is presented for validating an airport simulation model. The emphasis is on basic principles of validation and inherent problems in comparing simulation model estimates with observable real-world data. The validation procedure consists of three major steps: (1) An evaluation of model logic, assumptions, inputs, and outputs; (2) a sensitivity analysis of the model estimates; and (3) a comparison of model estimates with observed data. An examination is presented of two important statistical considerations for simulation models: auto-correlation and model convergence. Guidelines are given for interpreting the results of statistical hypothesis tests.
