Validation Validation is the task of determining if the model constructed accurately represents the underlying real system being modeled. For any simulation model that is to be used in actual application it is very important to validate the model insofar as practicable, since real decisions are going to be made based on the simulation outcomes. 10-1 Calibration, Adjustment and Validation, Part 1 · Lecture Slides .
