STUDY OF SYSTEMS AND COST/PERFORMANCE METHODOLOGIES FOR OPTIMIZATION OF VEHICLE ASSIGNMENT FINAL REPORT VOLUME 1TECHNICAL DESCRIPTION

摘要

During this study, analysis is performed and computer programs developed for optimal assignment of expendable and reusable launch vehicles in a multi-year, multi-mission space program. A primary objective is provision of an analytical tool to help the advance planner to maximize, under restrictive budget constraints, the accomplishment of a future space program. Such a program will normally include existing vehicles, growth versions, and new starts. Explicit handling of all contributing and interrelated costs (recurring, nonrecurring, and sustaining) ensures global solution for a previously intractable problem. The programs analyze the multiple factors that apply, including stage and vehicle characteristics, mission requirements, production aspects, launch sites and pads, sustaining effort, and others. A single computer run identifies stages and vehicles that comprise the optimum launch vehicle family and provides an array of data pertinent to this optimum. An integrated vehicle assignment and budget smoothing feature provides for optimal accomplishment of a space program without exceeding yearly budget constraints.
