✦ Synopsis
In this paper, it is proposed that using knowledge-based technology to generate different types of models of a target domain can better assist designers of support systems. The main argument is that designers' decisions should be based on knowledge about a domain rather than on their "common sense" judgments. This approach is illustrated by describing a canonical user model capturing operators' information and knowledge acquisition behaviour. In the present work, this model is used to help designers identify what process variables need to be associated with flow diagrams representing the structure of the technical system. Concepts underlying the user modelling approach as well as the knowledge elicitation and knowledge representation process are described. Finally, functionality provided by the user model is discussed as well as how the approach can be evaluated.
