Application-Driven Reliability Measures and Evaluation Tool for Fault-Tolerant Real-Time Systems

Trident Logo

As the use of fault-tolerant systems in life-critical applications continues to increase, so does the need for appropriate and meaningful reliability prediction for such machines. Application-Driven Reliabilility Measures for Real-Time Systems was a 3-year project, funded by DARPA, which focused on the study and development of a new reliability measure and prediction tool for fault-tolerant, real-time, distributed systems.

Our work consisted of defining new fault-tolerance measures that are more appropriate to real-time systems than the measures available, developing mathematical models for computing such measures for computer systems, and building a software tool to implement these models.
