Simulation by Logical Modeling of Costs

The Simulation by Logical Modeling of Costs (SIBYL/COST) software subsystem is used by logistical and financial analysts to develop cost projections of labor and hardware requirements for preparation of space shuttle main engine (SSME) spares proposals, SSME program operating plans (POPs), and special engine-cost studies. SIBYL/ COST makes projections of program resource requirements, identifies potential program threats and associated costs, evaluates adjustments of scope to meet funding levels, supports decision packages for pre- and post-POP exercises, and provides sufficient detail to support operating plans, team budgets, and changes in contracts for subsequent years.
