SIMULATION MODEL VERIFICATION AND VALIDATION: INCREASING THE USERS ’ CONFIDENCE

This paper sets simulation model verification and validation (V&V) in the context of the process of performing a simulation study. Various different forms of V&V need to take place depending on the stage that has been reached. Since the phases of a study are performed inan iterative manner, so too are the various forms of V&V. A number of difficulties with verifying and validating models are discussed, after which a series ofV&V methods are described. V&V is seen as a process of increasing confidence ina model, and not one of demonstrating absolute accuracy.
