Simulation based operational analysis of future space transportation systems

This paper presents an approach to the operational analysis of future space transportation systems. The approach combines knowledge from government and industry space operation and design experts, with system analysis methodologies to predict operational characteristics of a future space transportation system. The model proposed under this approach utilizes expert knowledge to predict the operational requirements of a vehicle concept, including the ground activities, flows, resources, and costs; all the components of the spaceport. The model incorporates simulation in order to include spaceport characteristics as alternative flows, processing variability, and other random events. This model will provide vehicle designers with useful understanding of the spaceport operations related to the investigated vehicle design. A stand-alone application is being developed where the model will be implemented and validated.
