Designing Reliable Cyber-Physical Systems

Cyber-physical systems, that consist of a cyber part—a computing system—and a physical part—the system in the physical environment—as well as the respective interfaces between those parts, are omnipresent in our daily lives. The application in the physical environment drives the overall requirements that must be respected when designing the computing system. Here, reliability is a core aspect where some of the most pressing design challenges are: monitoring failures throughout the computing system, determining the impact of failures on the application constraints, and ensuring correctness of the computing system with respect to application-driven requirements rooted in the physical environment.
