      Fault diagnosis in discrete event systems modeled by partially observed petri nets 

      Ru, Y.; Hadjicostis, Christoforos N. (2009)
      In this paper, we study fault diagnosis in discrete event systems modeled by partially observed Petri nets, i.e., Petri nets equipped with sensors that allow observation of the number of tokens in some of the places and/or ...

      Fault diagnosis in discrete event systems modeled by petri nets with outputs 

      Ru, Y.; Hadjicostis, Christoforos N. (2008)
      In this paper, we study fault diagnosis in discrete event systems modeled by Petri nets with outputs, i.e., Petri nets with place sensors and transition sensors. Faults are modeled as unobservable transitions and are divided ...

      Monitoring discrete event systems using Petri net embeddings 

      Hadjicostis, Christoforos N.; Verghese, G. C. (1999)
      In this paper we discuss a methodology for monitoring failures and other activity in discrete event systems that are described by Petri nets. Our method is based on embedding the given Petri net model in a larger Petri net ...

      Power system monitoring based on relay and circuit breaker information 

      Hadjicostis, Christoforos N.; Verghese, G. C. (2001)
      In this paper we develop monitoring schemes that are able to detect and identify failures in power transmission lines by analyzing binary status information from relays and circuit breakers. The approach, which is based ...
