隨著生活水平提升，人們對於美的解釋是具多元化與自我意象的定義，藝術指甲彩繪由過去的保養護理躍升為具有設計感、時尚感與藝術美學的活動，而如何有效的掌握指甲彩繪設計要素以利設計工作之進行，對設計師而言顯為重要。因此本研究為使美甲設計者在創作過程具有參考準則，應用詮釋結構模式探討藝術指甲彩繪設計因素間的從屬與層級關係，並導出階層式結構圖，得到其各設計要素之間的結構關聯性，並以層級分析法計算其權重，以協助設計者有效分析各個因素之間的關聯與順序。研究結果顯示，由設計要素關聯圖與權重計算，可明確得知在設計指標的相互關係與重要性，其中指甲彩繪之設計表現以「整體性表現」（51%）為最高權重，其次為「構圖」（17.1%）與「美感」（16.7%）並列第二，「色彩」（16.5%），排名第三。藉此可知，指甲彩繪作品之設計品質，乃取決於整體感畫面的視覺是否協調合宜為主。藉此成果可形成較清楚的脈絡，提供對複雜事務的決策協助，以利設計者處理複雜設計因子的參考。

With the improvements of life standard, the definitions of beauty are now along with our diversities and self-images, differ from the caring purpose in the past; nails art has now become an activity with creation, fashion and aesthetics. And how to effectively grasp the nail art design elements to make the design work carried out smoothly, it is important for designers. Therefore, in order to provide a design criterion for nails art designers, the study applies Interpretive Structural Modeling (ISM) to investigate the dependability and hierarchical relation of nails art design factors, by leading out the hierarchical structure, the study gets the construction relevancy of the design factors, and calculates the weights with The analytic hierarchy process (AHP), which makes designers efficiently analyze the relation and sequence. The result of the study shows that with the factors association graph and weight calculations, we can get the relationship and importance comparison between all those design factors. The performance of nail art designs to ＂holistic performance＂ (51%) for the highest weight, followed by ＂composition＂ (17.1%) and ＂beauty＂ (16.7 %) tied for second, ＂color＂ (16.5%), ranking third, from here you can know the quality of the design is a nail painting works of the screen depending on is the overall sense of visual coordination expedient. This result can be formed by relatively clear context, providing complex affairs decisions assistance to help designers deal with complex design factor reference.
