OPSMODEL, AN ON-ORBIT OPERATIONS SIMULATION MODELING TOOL FOR SPACE STATION

AN operations analysis and planning tool (OPSMODEL) has been developed by Computer Sciences Corporation for NASA Langley Research Center to provide realistic modeling and simulation of on-orbit crew operations for a space station. The IBM PC compatible program produces a quantitative measure of the effectiveness of the on-orbit crew's activities under alternative space station designs, technologies, and operational policies. The OPSMODEL also supports engineering and cost analyses and operations planning activities. The simulation can be monitored on-line with the focus and level of detail selected by the user. Other outputs include engineering performance indicators, such as crew times and space station status, cost performance organized according to work breakdown structure, and various data products extracted from a time-tagged event log recorded during the simulation run.
