This development effort is aimed at the definition of a comprehensive expert system for the study, management, and analytical treatment of Contamination Control technologies, including treatment and processing of flight measurement data. The system will provide management support, flight data and historical data utilization, selection and performance of analytical steps, and contamination program monitoring.j The proposed innovation will also be apable of integrating historical data to current programs, thereby providing comprehensive support to the Contamination Engineering approach implementation. No currently available implementation provides such a level of engineering support, user control, and flexibility. The system as such, or evolutions, thereof, may find applications within many NASA endeavors, as well as in commercial environments.A technologically advanced software system of the type proposed here will find a wide range of applications in the commercial arena. Commercial organization will be interested in this product, including: spacecraft developers, engineering companies, clean-room technology companies, etc. Several Agencies of the Federal Government may have a very strong interest in applying this technology.contamination control, expert systems, engineering supportSTATUS: Phase I Only
