This report describes human-centered modeling efforts recently completed or ongoing so that users and developers of military C3I systems quantitatively assess changes in operational procedures and information technology brought about by today's political-military climate. One model is an information flow and task workload simulation, another is a rule-based information quality assessment model, and a third is a tool to model skill-ability demands for C3I jobs. Although each model has proven highly useful and successful independently, an intelligent interface linking all three models is proposed. This in effect establishes a C3I meta-model, where users can directly visualize and frame their C3I system questions, using a query and feedback interchange, and the interchange results are automatically translated to model terms and variable settings, and computational instructions.
