A COGNITIVE MODEL FOR REPRESENTING KNOWLEDGE INTENTIONS AND ACTIONS OF PROCESS PLANT OPERATORS
This paper describes several mechanisms being elaborated for the simulation of the mental and behaviouristic activities of process plant operators during normal and emergency situations. The restriction of the reality to be captured, plant- operator interaction, facilitates the simulation enterprise although nothing proves that the closure of the environment induces an isomorphic limitation in the cognitive semantic field being considered. Formally, the description of the model considers two cognitive levels. item - A High Level Decision Making (HLDM) where the operator is involved in two continuous and parallel activities i.e. to recognize the current behaviour of the plant and to elaborate strategies in order to maintain or bring back the plant at nominal conditions. item - A Low Level Decision Making (LLDM) which essentially consists of the implementation of the operator's strategies as well as the convergences or divergences between the operator expectations and the observed actual plant response. This LLDM has often been referred to in previous works and will therefore be briefly reviewed.par The paper will mainly tackle the HLDM part of the model.
