The first of a two-course sequence that is part of the engineering science foundation for subsequent courses in systems engineering. This course builds on the scientific method and problem solving paradigms embedded in the basic sciences by introducing cadets to the modeling process and many of the classical deterministic models used by systems engineers to analyze decision alternatives. The emphasis is on the creative application of skills learned in the basic sciences to model formulation, solution methods, analysis of results, and interpretation. Models studied include inventory systems, linear programming and its extensions, networks, and project scheduling (PERT/CPM). The course requires cadets to use computer software for model solution and analysis. Communication skills are developed with both written reports and oral presentations. Cadets will spend twelve to twenty lessons in a computer lab environment.
