A report discusses the development of a highly complex system of distributed-computing, multidisciplinary design-optimization software, called "CJOpt," for use in research on model 4 of the High-Speed Civil Transport (HSCT) airplane (HSCT4.0). The emphasis in the report is on the application of formal software configuration management (SCM) to ensure the integrity of, and the traceability of changes in, the optimization software.
