The effort was directed by Mr. B. H. Campbell. Mr. R. D. Kramer, Marshall Space Flight Center and Mr. R. R. Carley, NASA Headquarters were the NASA Study Directors for this study. Their efforts in providing technical direction throughout the duration of the study are greatly appreciated. This volume is one of three volumes of the final report for Study 2.3. The three volumes are: Volume I Executive Summary Volume II Systems Cost/Performance Model Appendix Data Base Volume III Programmer's MIanual and User's Guide Volume I summarizes the overall report. It includes the relationship of this study to other NASA efforts; significant results, study limitations, and suggested additional effort. Volume II provides a detailed description of the Systems Cost/ Performance Model. It also includes the model checkout and the results for three payload test cases. The Data Base is provided in the Appendix to Volume II. Volume III provides a detailed description of how the Systems Cost/Performance Computer Program is organized and operates. The program listing,, detailed flow charts and user restrictions are included.
