Discrete and Hybrid Systems Dependability Analysis with ESA PetriNet

International audience; Based on Petri net modelling and linear logic as formal framework, ESA PetriNet allows to carry out dependability analysis of discrete (based on temporal Petri nets modelling) or hybrid systems (differential predicate-transition Petri nets modelling). ESA PetriNet implements the approach for critical scenarios deriving. The approach is based on a qualitative analysis of Petri net model. It consists in determining a sequence of events represented by transition firings in the Petri net model that leads the system from normal working to critical situation. ESA PetriNet allows deriving only pertinent scenarios. Minimality of these scenarios (composed by the necessary events) is introduced to facilite the analysis step.
