One of the major safety issues of modern technological society is the consideration of human factors and human behaviour in the design of control systems. The problems which a designer and a safety analyst have to face when studying the plant control and supervisory systems are twofold; how to consider the event of human errors in the design of safety features and in the evaluation of the associated risk, and how to improve and validate the procedures and man-machine interaction in order to account for the complexity of the system and the intrinsic dynamics of accidents and transients. The role of cognitive ergonomics as a new discipline dedicated to bridging the gap between the sciences of engineering and psychology is very important for the development of new design strategies of plants and control systems based on profound consideration for human-machine interaction processes. In this paper, cognitive ergonomics is elaborated from three perspectives: (i) cognitive ergonomics and human-machine systems; (ii) the function of cognitive ergonomics in human reliability analysis; (iii) the contribution of cognitive ergonomics to the modelling of decision-making.
