PROBLEM TO BE SOLVED: To rearrange/analyze product attributes constituting respective hierarchies at the time of analyzing the attribute hierarchies, analyzing them, to clearly analyze which element among elements that product data has gives what type of influence and to clarify criteria at the time of analyzing the attribute hierarchies and analyzing an attribute matrix in a product data analysis device. SOLUTION: Attributes constituting the respective hierarchies of the attribute hierarchies used for analyzing the attribute hierarchies can be made independent and product attributes which are set in the respective hierarchies of the attribute hierarchies can be rearranged (#3). When the product attributes are rearranged, data corresponding to the changed attribute hierarchy is accumulated (#4). At the time of analyzing the attribute hierarchy, product data can be analyzed by using accumulated data corresponding to the rearranged attribute hierarchy. |
