A systematic logic for the validation of digital simulation models is presented and applied to the validation of a previously developed model for simulating the acts and behaviors of intermediate size crews as they perform system operation tasks. The mission simulated was a trust territories reconnaissance by a patrol gunboat PG class Navy ship. The results indicated that the validation logic employed the multimethod-multitrait approach aided in the identification of both model and criterion error. Identification of both error sources is required if model improvements and revisions are to be implemented. The results of the various analyses, completed on the basis of an initial multimethod-multitrait matrix, indicated support for both the convergent and the discriminant validity of the simulation model.
