隨著國人生活品質的提升與自我意識增強，消費者在購買成衣服飾時，不僅是經濟因素考量，更包含個人化的需求。使得成衣設計者面對消費者需求的改變及同業競爭激烈的情況下，除了仰賴自身經驗外，還有哪些關鍵指標因素會影響成衣設計便顯得格外重要。本研究旨在以修正式德菲層級程序法，建構成衣設計指標評價模式。研究首先以修正式德菲法專家問卷評定，篩選出在專業考量上具有高度共識的成衣設計指標，而後運用分析層級程序法進行專業評估，最後取得具優勢的各項設計指標之相對權值，並作一致性檢定與分析。研究結果顯示，設計指標前三項為設計原則的掌握與應用、布料特性的暸解、藝術素養與美感，藉此成衣設計指標建構，可提供成衣設計與開發之參考。

With the increase in living quality and self-awareness, customers consider not only economic factors, but also personal requirements while making purchasing decisions. In addition to expertise in design, designers must consider the key factors that influence designing to face the change of consumer demands and the competitiveness of the craft. This study adopted the Modified Delphi Hierarchy Process (MDHP) method to establish an index in apparel design. First, this study established the index in apparel design by the Modified Delphi method of expert questionnaires to sift the design guidelines that are commonly agreed upon. Next, the Analytic Hierarchy Process (AHP) method was applied to conduct professional evaluations and obtain relative weights of indicators
under the examination of inconsistency assessment. Study results show that the top three design indices are the application of design guidelines, understanding of fabrics, and artistry and esthetics. Based on this design index, we can attain crucial references in apparel design and development.
