Computer simulation is recognized as a valuable systems analysis research tool which enables the detailed examination, evaluation, and manipulation, under stated conditions, of a system without direct action on the system. This technique provides management with quantitative data on system performance and capabilities which can be used to compare proposed methods, concepts, or designs. The planning of a new Navy technical school provided the opportunity to demonstrate the feasibility and value of simulation as applied to training systems. The school was being programed to use individualized self-paced instructional systems and, therefore, was considered to be representative of future instructional systems in the Navy. Not only would the replication of the system prove the feasibility of the application of simulation, but it would provide the training planners with the capability of assessing their particular conceptual system and of checking the validity of their assumptions.
