| The paper based on the characteristic of Rough Sets classification and applies it to Data Mining to guiding product conceptual design. The paper discusses the method of design parameter's predigestion guided by Rough sets and apply concept climb based on attribute to design Database, thus we can obtain relation rules between design parameter and design scheme from all kinds of abstract hierarchy and different point of view. Combine problem of mechanism transmission scheme design, a framework that sustain product concept design is established. Based on design database search from Internet, design parameters are predigested. The most important parameters that make sure to transmission style are available, so that the search range is shrinked and the complexity is reduced. The multi-predigest mining between design parameter and transmission scheme is realized and relation rules of all kinds of abstract levels are obtained. Finally, a system of mechanism transmission conceptual design guided by Data Mining based on Rough Sets is developed in order to validating above works. |
