PX1: a space shuttle mission operations knowledge-based system project

A knowledge-based system (KBS) prototyping project is examined. The work entails reasoning about the impact of component failures in space shuttle orbiter subsystems. The effort is directed toward the development of a system that will recognize passive component failures as potential safety hazards, rather than toward an active failure identification or diagnostic tool. The system was designed to be integrated as a knowledge-based processing system utilizing input from a procedure-based processing system. Implementation of the consolidated system will occur when real-time telemetry data is available at the workstations. The system may be used standalone in the meantime. Flight controllers at the Johnson Space Center will use this prototype to help develop requirements for a space shuttle mission operations tool
