Abstract

This study is about product design features based on customer requirements using a crisp and fuzzy analytical hierarchy process (AHP and F AHP) method. In this study, the respondents involved were the higher education students in Melaka. The survey conducted towards 1000 respondents with the questionnaires developed using the 3 proposed design characteristics, that were containing of 6 design types respectively applied in the scaled I to 7 of semantic differential to Kansei words. The objective of this study is to identify, analyze, justify, and evaluate the features and design requirements of the product, beside to generate the decision making in order to find the preference or priority of the products. As a case study, this study was conducted towards the spectacles design. The Post Test survey is required in order to validate the results, beside the correlation analysis. Based on the results data, all of the Kansei words used in this study were valid, since all of the Cronbach alpha values were more than 0. 7. The Kansei words identified through 30 respondents, as the articulation of the product design characteristics are 'Boring- Attractive' (B/A), 'Common- Unique' (C/U), 'Lame- Cool' (L/C), 'ClassicModern' (C/M), and 'Fragile- Robust' (FIR). While the most preference design characteristics related to the proposed design, is Full Rim characteristic. To the Kansei words, the most preference was on "Lame- Cool" (L/C) word, where the highest value was occurred on the type- 6. This finding is similar and proven through the Post Test survey conducted. Towards the respondents' background, the ' Optical Power' is having significant correlation (p<O.Ol) to ' Boring-Attractive' of Kansei word. Based on this reason, the decision made to customer requirements should be carefully determined by the comparison analysis, especially to each criterion using Kansei Words as an articulation of customer quality feelings.
