Software Reliability for Safety-Critical and Mission-Critical Systems: Functional Safety, Real-Time Systems, Cyber Resilience, and High-Assurance Software Engineering

Software Reliability for Safety-Critical and Mission-Critical Systems

When software fails, lives, missions, and critical operations can be at risk.

From aircraft flight-control systems and autonomous vehicles to medical devices, railway networks, industrial automation platforms, defense systems, telecommunications infrastructure, and critical utilities, modern society depends on software that must operate safely, securely, and reliably under demanding conditions.

Software Reliability for Safety-Critical and Mission-Critical Systems is a comprehensive engineering guide to designing, developing, testing, certifying, and maintaining dependable software for environments where failure is unacceptable.

Combining proven reliability engineering principles with modern software practices, this book provides a practical framework for building fault-tolerant, resilient, real-time, high-assurance systems capable of meeting the rigorous demands of safety-critical and mission-critical applications.
