      Probabilistic approaches to fault detection in networked discrete event systems 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2005)
      In this paper, we consider distributed systems that can be modeled as finite state machines with known behavior under fault-free conditions, and we study the detection of a general class of faults that manifest themselves ...
