The Design of Training Systems (DOTS) project was initiated by the Department of Defense (DOD) to develop tools for the effective management of military training organizations. Phase 2 involved the design and development of three computer-based mathematical models, described in detail in this report. The models described are the System Capabilities/Requirements and Resources Model, the Educational Technology Evaluation Model, and the Training Process Flow Model. Model logic design, input/output parameters, and data base communications are discussed at a level which allows an analytical evaluation of each model's design. Model test scenarios are described together with probable applications for the DOTS models. (DGC)
