Model Validation

Abstract

Validation of a simulation model provides assurance or confidence that the model is sufficiently adequate and appropriate for use according to the purpose of the model. Validation deals with ensuring that the model closely represents the real system. This should address the concerns of users that the model and results of its simulation runs are acceptable within certain range specified by the purpose of the model. Verification of the simulation model deals with ensuring that the model is correctly implemented. If a model has not been validated, it is unlikely that it will be used in a real-world setting. In order for a model to be acceptable, the model should be thoroughly verified and validated before use. This chapter presents an overview of several concepts and techniques for verification and validation of simulation models.
