A Meta-cognition Modeling of Engineering Product Designer in the Process of Product Design

摘要

For further effectual tacit knowledge reusing in the process of product design, individual cognitive processes, cognitive factors, and cognitive strategies need to be realized to find the essential factors that affect the generation of tacit knowledge and control designer activities in the whole design process. But these key factors are relative to individual cognitive capability and meta-cognitive level. So, based on physical symbol system hypothesis (PSSH) and connectionism, a meta-cognition model of engineering product designer is provided to elucidate the active monitoring and consequent regulation in this paper. Designers' cognitive activities in the process of product design are analyzed from the viewpoint of cognition science. Finally, the cognitive differences between the experienced designers and the novices in the process of fuel injection bump design is compared and elaborated in detail.
