多準則群體決策法在評選室內設計師之應用

Application of Multi-criteria Group Decision-making Method in the Selection of Interior Designers

全台登記有案之室內裝修業超過1萬家，而各室內裝修業者，該如何評選出優秀之室內設計師？引進人才以增加公司之獲利，確實有進一步研究探討之必要。本研究採用層級分析法（AHP）結合田口損失函數、AHP結合偏好順序評價法（TOPSIS）及模糊偏好順序評價法（fuzzy TOPSIS），來評選合適之室內設計師。13項與選擇合適之室內設計師有關之評估準則，藉由模糊德菲法（FDM）取得共識。本研究以AHP問卷及分析求得13項評估準則之權重。並採用下列三種方法求得三位室內設計師候選人之排名。方法一是以AHP所得之權重結合田口損失函數計算各候選人之加權田口損失值，加權損失值愈小之候選人其排名愈好。方法二與三則是分別以AHP結合TOPSIS及fuzzy TOPSIS，求得各候選人之接近係數，根據接近係數之大小來進行候選人之排名，接近係數愈高之候選人排名愈好。研究結果顯示，三種評選室內設計師方法中，以fuzzy TOPSIS為最佳。本研究之成果可作為大型室內設計裝修業尋求合適之室內設計師之參考。

There are more than 10,000 interior decoration companies registered in Taiwan. How can each interior decoration company select the outstanding interior designers? The introduction of talents to increase the company's profits is indeed necessary for further research. This research aims to select a proper interior designer by the analytical hierarchy process (AHP) combined Taguchi loss function, AHP combined Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and fuzzy TOPSIS, respectively. Thirteen criteria associated with the selection of a proper interior designer reach consensus by fuzzy Delphi method (FDM). The weightings of 13 criteria are obtained from AHP. Three analysis methods are adopted to determine the rankings among three interior designer's candidates. In the method of AHP combined Taguchi loss function, the smaller the weighted Taguchi's loss values, the better is the order of the candidates. In the method of AHP combined TOPSIS and fuzzy TOPSIS, the larger the coefficient of closeness, the better is the order of the candidates. The results of this study indicate that fuzzy TOPSIS is the best method in selecting a proper interior designer. The results of this research offer a reference for the interior design and decoration industry to find a suitable interior designer.
