Bounds on the number of markings consistent with label observations in petri nets
(2009)In this paper, we consider state estimation in discrete-event systems (DESs) modeled by labeled Petri nets and present upper bounds on the number of system states (or markings) that are consistent with an observed sequence ...

Designs of bisimilar Petri net controllers with fault tolerance capabilities
(2008)This paper proposes an approach for providing tolerance against faults that may compromise the functionality of a given controller modeled by a Petri net. The method is based on embedding the given Petri net controller ...

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

Fault model identification with petri nets
(2008)Most of the fault identification problems in the Discrete Event Systems literature assume knowledge of the structure of the net system, including the nature (and behavior) of the possible faults. In this paper we deal with ...

Fault-tolerant supervisory control of discrete event systems modeled by bounded Petri nets
(2007)This paper considers bounded Petri nets with both controllable and uncontrollable transitions, and addresses the synthesis of a fault-tolerant supervisor in a setting where the control specifications are described via ...

Least-cost firing sequence estimation in labeled Petri nets with unobservable transitions
(2007)This paper develops a recursive algorithm for estimating the least-cost transition firing sequences that match the observation of a sequence of labels produced by transition activity in a given labeled Petri net. The Petri ...

An operational European global ocean observing system for the eastern Mediterranean Levantine Basin: The Cyprus Coastal Ocean Forecasting and Observing System
(2003)The countries surrounding the Mediterranean Sea have joined together in several multinational initiatives to conduct long-term, integrated, operational oceanographic observations and modelling of this important region. ...

Supervisor synthesis for discrete event systems with arbitrary forbidden state specifications
(2008)In this paper, we consider the forbidden state problem in discrete event systems modeled by Petri nets with uncontrollable and/or unobservable transitions. To handle the interleaving of uncontrollable and unobservable ...
