Applied study of the method to presume the decision class by Variable precision rough sets model

Abstract

It has been shown that the method of presuming the decision class is important to extract the feature of the product design from case studies that we researched. As a method of presuming the decision class, we paid attention to Variable precision rough sets model proposed by Ziarko which can treat the contradiction between data, and we proposed the method. We discussed the possibility of this presumption method through a current application research to the case.
