Abstract
In this paper, we show that the power set of attributes of the furniture for indoor public spaces constitutes a fuzzy measure. From the results, by using fuzzy integrals, we propose a fundamental methodology for obtaining an overall rating of the furniture. Also, we have shown practical examples in order to show the effectiveness of the method proposed here. An experiment that researched how much an evaluator puts importance on each property was conducted for specialists of furniture manufacturers and a user group in their twenties. We clarified the difference of their viewpoint between users and manufacturers by comparing the results. We found out what were fundamentally desired by the evaluators by not only numerically measuring the values of importance that the evaluators comprehensively put on the combinations of individual attributes, but also hearing about the newly created values that the evaluators saw in the combinations of values.
