Application of Multi-Criteria Group Decision-Making Method in Interior Decoration Service

Abstract

<p>值此消費者導向時代，室內設計公司應秉持以客為尊，針對客戶住宅之條件做出最適合之裝修建議，為客戶提供最完整，最優質的室內裝修服務，從而為公司贏得比其他公司更好的聲譽。五項與選擇天花板、壁面及地坪裝修有關之評估準則，依次藉由專家訪談、初步問卷及模糊德菲法(fuzzy Delphi method, FDM)取得。本研究以3個業主住宅之天花板、壁面及地坪之12個裝修項目做為研究對象，採用層級分析法(analytic hierarchy process, AHP)結合偏好順序評價法(technique for order preference by similarity to ideal solution, TOPSIS)及模糊偏好順序評價法(fuzzy TOPSIS)兩種不同分析方法，對每個裝修項目中之各替代方案進行擇優排名。12個裝修項目中，對於不同業主採用AHP結合TOPSIS及fuzzy TOPSIS兩種不同方法計算之結果顯示，共有客餐廳天花板、臥房天花板、客餐廳壁面及臥房地坪等四個裝修項目所得各替代方案之排名順序皆相同。對於廚房天花板及浴室壁面之裝修，同一業主採用AHP結合TOPSIS 及fuzzy TOPSIS兩種不同方法所得各替代方案之排名順序皆相同。兩種不同分析方法對於家庭成員僅有二人之業主3所得排名結果差異不大。本研究認為家庭成員愈多之大家庭在替代方案之排名順序應該以更具有參考價值之fuzzy TOPSIS所得之結果為準。</p> <p> </p><p>In this consumer-oriented era, interior design companies should adhere to the principle of customer-oriented, make the most suitable suggestions for the conditions of customers’ houses decoration, and provide customers with the most complete and high-quality interior decoration services, so as to win more good reputation than other companies. Five evaluation criteria related to the selection of ceiling, wall and floor decoration were obtained through expert interviews, preliminary questionnaires and fuzzy Delphi method in turn. This study takes 12 decoration projects of ceilings, walls and floors of 3 owners’ residences as the research objects, using the analytic hierarchy process (AHP) combined with the technique for order preference by similarity to ideal solution (TOPSIS) and the fuzzy TOPSIS methods to rank the alternatives in 12 decoration projects. The identical ranking order results were obtained for three owners by AHP combined with TOPSIS and fuzzy TOPSIS in the ceiling of the guest dining room, the ceiling of the bedroom, the wall of the guest dining room, and the floor of the bedroom. For the decoration of kitchen ceilings and bathroom walls, the same owner uses AHP combined with TOPSIS and fuzzy TOPSIS two different methods to obtain the ranking order of the alternatives are the same. There is little difference in the ranking results obtained by the two different analysis methods for owners 3 with only two family members. This study believes that the ranking order of alternative programs for large families with more family members should be based on the results obtained by fuzzy TOPSIS, which has more reference value.</p> <p> </p>
