Risk Modeling and Analysis of Interdependencies of Critical Infrastructures Using Colored Timed Petri Nets
نویسندگان
چکیده
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.

Using Interval Petri Nets and Timed Automata for Diagnosis of Discrete Event Systems (DES)
A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...

متن کاملA rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
