In this study, a framework to model the effects of stress on a process control operator is proposed. There exists many cognitive models, each of which attempts to model a specific class of human behaviour. One major effect of stress is the cause of errors, both physical and cognitive. In order to model the effects of stress, two cognitive models, a cognitive model of human errors and a cognitive model of process control operators are examined in detail. In this thesis, the basic functions of the human cognitive system, its organization and a cognitive model of error commission are first examined. The behaviour of a process control operator and a cognitive model of the behaviour of the operator are then discussed. The known effects of stress on the process control operator's behaviour are described and a framework for modelling the behaviour of process control operators under stress is proposed. The inadequacies associated with existing cognitive models for process control operators are explained and a modified cognitive model is proposed, which takes into account the cognitive model of error. Finally, an architecture design for the implementation of the cognitive model is provided and suggestions for the next step forward are proposed.
