The validation of the simulation model is generally acknowledged as an integral part of a simulation project. There is, however, no general agreement on how simulation models should be verified and there is often confusion as to the difference between validation and verification. In this paper we first set forth a framework for verification and validation as well as some of the more commonly suggested methods to be used. We then turn to the literature on the application of simulation to see how models are, in practice, verified and validated. To our surprise we found that in the vast majority of the reported applications of simulation there is no mention of verification or validation of the simulation model, and when it is included, typically a single sentence or two is all that is devoted to how the model's credibility was established. We classified reported applications by type of author, organization type and source and found no significant difference in the frequency of the inclusion of verification or validation as part of the reported application.
