Ontology‐Based Accidental Process
Jean‐François Aubry, Nicolae Brînzei, Mohammed‐Habib Mazouni · 2016
A state/transition model appears suitable for the representation of an ontology-based accidental process. This chapter specifies the entities' types, their successive states and the events associated with these state changes. A hazard supplier entity (HSE) is an entity likely able to carry or generate one or several hazards under given circumstances. The vulnerability characterizes the potentiality of a vulnerable target entity (VTE), when exposed in a hazard space, of being able to undergo given damage. The authors choose Petri nets (PNs) as a model for the representation of the accidental process in a system where entities are interacting. As a result, they reserve the term state to qualify the marking vector of the PN modeling this process. To characterize the state of an elementary entity, the authors reserve the term situation. An event is the dual concept of state of an entity.
