In this paper, a discrete event dynamic system (DEDS) approach is utilized to improve the reliability of a system from the faulttolerance viewpoint. We propose a systematic way to classify faults and failures quantitatively and to find tolerable fault event sequences embedded in DEDS’s. After this, the synthesis of a fault-tolerant supervisory control system is investigated. A case study of a p...
