Knowledge Representation for Engineering Design Based on a Cognitive Model

Abstract

For the computer-support of knowledge-based human information processing, it is necessary to look at the representation of the information as well as designing an appropriate interface considering the ergonomics of human-computer interaction. Related to the established methodology for the design of technical systems, the cognitive model of an abstraction hierarchy was used as a framework for a task-appropriate knowledge representation in every phase of the design process. Based on a design task from the field of mechanical engineering, this concept was implemented as a software prototype. In an empirical study the practical applicability and usefulness of this concept were investigated. Trajectories of design problem solving were recorded and analyzed.
