Abstract: A framework model of mult-i agent cooperative design system for pervasive computing is put forward.Considering the interaction among mobile facilities and mult-i channel information integration in the pervasive computing environment,the model appends the corresponding agents to the existing mult-i agent cooperative design system.To deal with the mult-i channel information,a design agent includes channel identification module,context generation module and mult-i channel information integration module.Knowledge representation based on design context and search-and-update learning algorithms are addressed in detail.Finally,the paper discusses about the knowledge sharing approach among multiple agents in a cooperative design system.This research will play an important role for the application of pervasive computing in design domain.
