應用品質機能展開於戶外休閒服飾設計程序之發展

Using Quality Function Deployment in the Development of Outdoor Leisure Apparel Design Process

服飾設計是一件非常複雜的工作，需要依賴製造技術、專家的經驗與顧客的需求。顧客的需求更被視為服飾設計成功的一項重要因素。基於此，本研究特運用品質機能展開法於服飾設計的程序中，以便能有效的將顧客需求與服飾機能特徵結合在一起，來強化服飾設計。本研究並利用分析層級程序法來輔助計算顧客需求的相對權重，以確保評估權值的準確性與一致性。 從分析結果中得知，顧客需求中有關“吸濕排汗能力好（N14）＂擁有最大的權值（21.59%）。此外，傳統的顧客需中，有關“造形美觀吸引人（N21）＂亦有較大的權值（14.77%），表示機能性與美學之間具有一平衡點，正可反映出真實的需求。而對整體性顧客滿意度的貢獻最大者為“排汗衣＋中層保暖衣+外層風雨衣（C52）＂佔9.17%，意指擁有較高優先權向量的顧客需求與設計型式，即為對整體性顧客滿意度有較高的貢獻程度，並可被視為創造成功產品的關鍵品質特性，應得到設計人員大部分的資源分配。整體結果顯示品質機能展開法，對於改良或開發新的產品，更兼具縮短前置時間與降低成本的高競爭力的優勢。

Apparel design is a very complicated task dependent on manufacturing technology available, expert experience and customer requirements. Customer requirements are considered as an important determining factor of success in apparel design. This research aims to link effectively customer requirements with functional characteristics using the concept of quality function deployment （QFD） in the apparel design process. In this study, the theory of analytic hierarchy process （AHP） is also employed to evaluate the importance of customer requirements so as to improve precision and verify consistency. The results demonstrate that among all customer needs, 'good perspiration-absorbance and vapor-permeability' （N14） has the largest relative weight of 21.59%, followed by the traditional customer requirement of 'good-looking and appealing style' （N21） with a high relative weight 14.77%. This indicates that the balance between aesthetics and functionality can reflect the real customer requirements. Moreover, functional apparel that can allow perspiration to evaporate, keep warmth, and resist both rain and wind （C52） contributes the most overall customer satisfaction. This implies that the higher priority the customer requirements and design characteristics have, the greater the satisfaction they contribute. These requirements and characteristics are key factors determining the success of new product design and should thus be allocated most of the design resources. In addition, the QFD method shows advantages in creating and redesigning products as well as reducing time and cost of production, thus enhancing competitiveness.
