櫥窗展示空間中，需要靠設計者本身具備有效且可靠的設計構思，以呈現空間之具象化和美感化。然而設計過程中，絕大部分設計方案，往往僅憑設計者個人經驗及刻板印象，在需考慮相衝突的目標因素下，進行難以控制且不精確的決策，造成設計評估時很難找到平衡點。因此，本研究首先透過現有資料蒐集與專家訪談，了解服飾陳列展示的現況，並獲得布料摺飾設計之評價目標，而後實際創作六款布料摺飾，並以熵值權重法，獲得各屬性權重值，再以TOPSIS法建構一套多屬性決策方法，以解決目標衝突情形時構想決策困難的問題，並評選出最佳構想方案。研究結果顯示，以不定褶與浮立褶技法，不規則下襬之公主線型輪廓線，最受專家所青睞。此模式之建立將有助於設計過程之理性化，降低評選失誤與提高評選決策效率，並提供設計者作爲選擇方案與修改構想等參考，進而增加商品促銷成功率。

The window-display design requires the efficiency and reliability of the designer to display the specification and beautification of spaces. However, most design estimation is fuzzy and there is a high level of uncertainty during this stage. The selection of design depends merely on the designer's personal experience, which makes finding a balance for design valuation difficult. By collecting literature and interviewing experts, this study got the evaluative guidelines, created six kinds of pin-work designs and applied Entropy to calculate the maximum of each guideline. We constructed a TOPSIS method model in an attempt to reduce the uncertainty and hesitation of choice process. The research result shows that the tucking, gathering, and princess silhouette was mostly accepted by experts. The development of this model was helpful in rationalizing the design selection process, lowering error rates in selection and enhancing selective decision efficiency.
