TRANSCOST: statistical-analytical model for cost estimation and economic optimization of space transportation systems

Abstract

The TRANSCOST Model for Space Transportation Systems Cost Estimation and Economic Optimization covers all three - quite different - areas of cost assessment: Development Cost or Non-Recurring Cost; Vehicle Recurring Cost (Flight units fabrication, assembly and verification cost); Flight Operations Cost (Direct and indirect cost). This 1991 edition of the TRANSCOST Model is the fifth version after the initial issue in 1980 and the follow-up versions of 1982 and 1983 and 1988. The model has been improved in almost all aspects taking into account additional cost data of the last years. It now comprises a data basis gathered over some 30 years. The specific improvement and extension of this issue is the attempt to extrapolate the model to the application for future projects of reusable and winged transportion systems - going beyond the statistic basis of past space projects, but taking into account aircraft propulsion and vehicle data as well as related operational and maintenance experience.
