Reliability of redundant architectures
In the realm of reliability engineering, redundant architectures like MooN (M out of N) and other parallel and majority architectures stand as pillars in safety-critical industries such as aerospace, rail transportation, nuclear energy, and autonomous driving. These architectures, designed with fault tolerance and self-diagnosis capabilities, ensure uninterrupted operation even in the face of component failures. Fail-operational systems maintain functionality despite faults, crucial for applications where downtime is not an option, like in autonomous vehicles. Fail-safe systems prioritize safety by reverting to a predefined safe state upon failure, essential for nuclear reactors and critical transportation systems. Dynamic reconfiguration allows systems to adapt in real-time, redistributing tasks and resources to maintain performance and safety. As these industries demand ever-higher standards of reliability and safety, the continued advancement of redundant architectures and fault-tolerant systems promises to complex infrastructures and complex dynamic systems against potential hazards.
