Study of visual evaluations for wood flooring applying fuzzy logic

This study was aimed to investigate the visual evaluations of wood flooring. The selected 12 species of wood flooring were simulated by computer and combined with the 6 sets of visual image adjectives to design a questionnaire and survey the visual evaluations of consumers. Triangular fuzzy number of fuzzy theory was employed to obtain the scores of the 12 species of wood flooring in the 6 visual image evaluations. The results showed that the differences between different species of wood flooring in the visual evaluation were less significant in terms of “classical and primitive”, “durable and practical”, and “natural and original”. However, the differences were more significant in terms of “Elegant and Soft”, “close and comfortable”, and “tender and amiable”. Furthermore, six groups with relative overall visual images were induced from the comparison of wood flooring by qualitative classification. For example, the overall visual images of Quercus rubra, Acer saccharum and Quercus alba were similar, and they were more “Elegant and Soft”,“durable and practical”,“close and comfortable”, and “tender and amiable”. The overall visual images of Carya ovata, Pinus rigida and Castanea sativa were similar, and they tended to be “classical and primitive” and “natural and original”.
