Simulating shuttle and derivative vehicle processing at KSC

Rockwell International Space Systems Division is teamed with the University of Central Florida on a research project to develop an automated simulation system to model ground processing scenarios for the Shuttle and Shuttle-derived vehicles. This simulation system is necessary to evaluate launch site facilities requirements and estimate life-cycle costs of future space programs. This paper presents the results of initial simulation modeling of the orbiter processing critical path at Kennedy Space Center (KSC). An approach is presented for the planned capabilities to simulate mixed fleet processing and to perform sensitivity, capacity, cost, and risk analyses. Potential expert system applications for the simulation system are presented, such as a resource allocation tool for stand-down periods or a long-range scheduling tool for future programs like the Space Exploration Initiative.
