This paper focuses on a rough set method to analyze human evaluation data with much ambiguity such as sensory and feeling data. In order to handle totally ambiguous and probabilistic human evaluation data, we propose a probabilistic approximation based on information gains of equivalent classes. Furthermore, we propose a two-stage method to simply extract(More)
Purpose – This paper proposes a new rough set based kansei engineering methodology, in which rough set model analyzes the interaction effects between principal components presenting customers’ need element and between product design category elements, and discusses its effectiveness and limitation through an application example to kansei product(More)
