METAKNOWLEDGE FOR TIME AND RELIABILITY

The task analyses of rapid process control highlight the significant place of knowledge about time and reliability in operators' activities. This knowledge is strongly involved in the adjustment of activity to the environment and to a knowledge about the operator's own capacities: a form of metaknowledge. The elicitation of that metaknowledge shows the importance of strategies oriented to the cognitive resource management. Some outcomes are discussed: the place of metaknowledge in cognitive modelling; the usefulness to integrate it in decision support systems designing such as pilot's intent recognition. A model of metaknowledge is proposed in the frame of combat aircraft pilots.
