Abstract:

A CASE Tool for Intelligent Diagnosis of Space Flight System Faults
Since computing systems are crucial components of space flight systems, the detection
and the isolation of flight software and hardware faults are critical in space-flight
data systems. Although modest progress has been made in improving hardware and software
reliability, there is currently a need for intelligent, fault-diagnosis in space-flight
data systems to allow for increased reliability, availability, and maintainability.
What is needed is a computer-aided software engineering (CASE) tool for intelligent
fault-diagnosis that incorporates the practical techniques from software fault-tolerance
in a knowledge-based expert system framework. The goal of this project is to develop
a CASE tool for intelligent fault-diagnosis using an in-house expert system shell.
The approach will allow the incorporation of software fault-tolerance techniques
into a knowledge-based expert system and demonstrate the feasibility of developing
a CASE tool for building an intelligent fault-diagnosis system in space-flight data
applications.
Commercial application would be a CASE tool assisting the implementation of intelligent
fault-diagnosis systems targeted to aerospace, electrical, mechanical, and chemical
engineering markets by federal contractors, government, and university research laboratories.
