This study presented a novel purchase rule based on grey relational analysis (GRA-rule) to evaluate the properties of PCs with high purchase involvement effectively. We further integrate this GRA-rule into a web-based consultative system (WebCS). As a result, consumers could utilize this system to obtain more decisive information that facilitated buying suitable PCs. First, we took and analyzed a questionnaire entitled “Demands of Purchasing PCs” over 1,500 persons so as to could reveal the trends of consumers’ demands for buying PCs possibly. From the data analyzed as above, we set eight factors for evaluating PCs, and then construct a corresponding weighted matrix of size 15×8. The GRA-rule would utilize such a matrix to rank all products of PCs to be evaluated. Moreover, the WebCS offered three types of weighted modes, including objectivity, subjectivity, and hybrid,...
