Abstract

This paper describes the architecture of a cognitive approach to modelling the behaviour of operators in the context of a man-machine simulation, focussing on the techniques used for representing reasoning processes. Simulations focus on models of human behaviour and plant response, which are integrated for the study of interactions during abnormal occurrences. The architecture System Response Analyser (SRA) relies on two levels. The first is "driver" through using the DYLAM method, which assures coupling of the second level - the "machine" and "operator" models, and manages the evolution of the accident. Human behaviour modelling concerns cognitive heuristics by which stored knowledge units are selected and brought into the working memory of the operator. Cognitive modelling can be used to conceptualize and formalize the expert's pieces of knowledge using a paradigm which can evolve into a useful expert system. Other uses include to support strength and prevent weakness of plant operators and to develop supervisory systems for accident prevention.
