The Space Command Optimizer of Utility Toolkit (SCOUT) is an integer linear program used by the Air Force Office of Aerospace Studies to help plan the research and development of space-based systems over a 25-year horizon. SCOUT recommends a mix of concepts, current systems, and launches that minimizes shortfalls in task performance while adhering to constraints on budget, launcher demand, launcher availability, and logic governing the precedence and interdependence of systems. This technical report provides a mathematical description of SCOUT, details several modifications, and reports computational experience. We find a significant reduction in solution time by using discount factors, and introducing the notion of continuous-valued research and development concepts.
