Representing design tradeoffs in safety-critical systems

Jennifer Morris, Philip Koopman
2005 Software engineering notes  
Different fault-tolerance strategies have been shown to be effective at achieving fail-safe behavior in a number of safetycritical application domains with different dependability, service, and cost requirements. A technique for comparing the domain profiles and their fault-tolerance strategies could assist architects of new safety-critical systems in choosing an appropriate fault-tolerance strategy. We suggest an approach using Kiviat graphs to visually represent the dependability, service,
