A generic model of experts' knowledge is required as a basis of good support tools for human-machine communication. The aim of this study is to construct a knowledge model of a plant opeator by behavior-speech analysis. An experiment was carried out in order to investigate substance of knowledge used in process control. Subjects' cognitive processes resulted in the observed performance were captured as logical formulae so that the knowledge used were elicited and classified. We adopted this approach with expectation that more reliable and elaborate analysis might be possible than classification by raw expert judgement. The analysis revealed that there are primarily four types of fundamental knowledge: state, goal, causality, and configuration. Subjects' cognitive processes in different experimental scenarios were characterized by classifying their utterances into the knowledge types and temporally tracing the processes. Consequently a knowledge model that consists of four spaces for describing knowledge of these four types and interrelations among them has been proposed.
