Petri Nets (PNs) and their variations are a graphical, mathematical language that can be used for the specification, analysis and verification of discrete event systems, including Critical Infrastructures (CIs). Colored PNs are an extension of classical PNs that are suitable for modeling and analyzing complex interconnected CIs. Timed PNs are another extension of PNs that support timing constraints and events. In this work we present a novel Risk Assessment methodology based on Timed Colored PNs for modeling and analyzing CIs with interdependencies, time-critical events and cascading effects. © Springer International Publishing Switzerland 2015.

Li, L.; Hadjicostis, Christoforos N.; Sreenivas, R. S. (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 ...
Calderaro, V.; Hadjicostis, Christoforos N.; Piccolo, A.; Siano, P. (2011)This paper presents a method to identify and localize failures in smart grids. The method is based on a carefully designed Petri net (PN) that captures the modeling details of the protection system of the distribution ...
Cabasino, M. P.; Hadjicostis, Christoforos N.; Seatzu, C. (2015)Given a labeled Petri net, possibly with silent (unobservable) transitions, we are interested in performing marking estimation in a probabilistic setting. We assume a known initial marking or a known finite set of initial ...
