In this paper the needs for developing a cognitive model of human behaviour are discussed and the architecture of a model of a plant operator, currently being developed, is described in some detail. Some potential applications of such type of modelling approach for the improvement of control room operators' training and the overcoming of human errors are overviewed. Progresses in these fields have a substantial impact on safety. Case studies analysis reveals that accidents in complex plants are mostly considered as unique events. The human model presumes a dual information processing architecture comprising a limited serial but computationally powerful working memory and a virtually limitless knowledge base, containing both declarative and procedural knowledge structures which are represented as frames. Finally it is shown how this modelling approach can be applied to training of operators. Normal control operations and accidents are simulated. Simulation reports are discussed with operators to make them aware of the aspects of their own behaviour which lead to human error.
