The cost of software fault tolerance
Gerard E. Migneault · NASA STI Repository (National Aeronautics and Space Administration) · 1982
The proposed use of software fault tolerance techniques as a means of reducing software costs in avionics and as a means of addressing the issue of system unreliability due to faults in software is examined. A model is developed to provide a view of the relationships among cost, redundancy, and reliability which suggests strategies for software development and maintenance which are not conventional.
