Simulation of Operators' Response in Emergencies

摘要

For the simulation of the accidential course of events in industrial process plants, a model is needed of operators' response to the cues presented by the system. A model is proposed, based on the simplifications which can be made when restricting attention to the operator functions having significants for a probabilistic risk analysis, and to anly skill and rule based performance, i.e., to responses in the early phase of an accident. The model is based on Brunswik's lens model, a model of the normal task repertoire, and on a taxonomy of human errors. To bring the model in perspective, a review of the state of the art of cognitive models of human behaviour is included. (ERA citation 12:034853)
