With the application fields of instrumentation and control system increasingly, reliability technology especially in some military, aerospace, nuclear power, industrial facilities, play an important role in improving the fighting capacity and maintain the normal working of large engineering and industrial production. These departments once faults occur, will lead to disastrous consequences. So the device reliability, security, maintainability, especially by the whole system includes measurement and control system, reliability, security, maintainability is particularly important. As in August 15, 2003, USA large area blackout is Canada, must not be a part of the equipment fault and extension caused!

Instrumentation and control system reliability technology in addition to reliability technology in the measurement device and a measurement and control system of its own, also including the affected by the fault processing technology of measurement and control device and system failure. The reliability of measurement and control device and system fault self diagnosis, including self isolation, fault self repair technology, fault tolerant technique, the reliability design technology, the reliability of manufacturing technology.
