Abstract: A context-centered design knowledge management technique was proposed to improve reuse efficiency of design knowledge. Design context was defined as application environments of the design knowledge, which included current design task and current designers attributes. Two essential components were a three-layer design process model comprising collaboration layer, intention layer and behavior layer and a user model combining a stereotype model and an overlay model. Workflow, tree hierarchy and hierarchical automaton were adopted to represent the above-mentioned three layers respectively. In user modeling, model stereotypes were classified and matched according to user properties and template contents would be defined based on domain knowledge architecture. The proposed technique employed context to facilitate the active recommendation of design knowledge items, which reduced negligence of key knowledge items and time to search for them. It offered wide application prospects and low cost of implementation without having to formalize the details of knowledge items or change their original formats.

Key words: design context, knowledge management, process modeling, user modeling
