Cyber physical systems (CPSs) typically have numerous sensors monitoring the various physical processes involved. Some sensor\r\nfailures are inevitable and may have catastrophic effects. The relational nature of the diverse measurands can be very useful in\r\ndetecting faulty sensors, monitoring the health of the system, and reducing false alarms. This paper provides procedures on how\r\none may integrate data from the various sensors, by careful design of a sensor relationship network. Once such a network has been\r\nadopted, choices become available in real time for enhancing the reliability, safety, and performance of the overall system.
