在今日的全球商業環境中，對所有企業而言，市場區隔的選擇是關鍵性的市場行銷活動。為了評估與選擇適當的市場，決策過程往往涉及多位決策者以及多重評估標準。本研究發展一混合式模糊集品質功能展開法(QFD)，該分析法以模糊集為基礎分析法，整合QFD 、AHP 以及TOPSIS 以評估與選擇適當的市場。建議的分析法中，利用模糊 QFD 確定內部特性的權重（WHATs）、評估市場區隔的外部條件 (HOWs) 、以及“HOWs”與“WHATs”之間的相關性程度。而模糊AHP 應用於評估標準的排序。依據值化的各項評估標準，以語言值評估市場區隔的選項，並以三角模糊數表示。然後，以模糊TOPSIS 獲取市場區隔選項的最終排序。最後，以汽車租賃公司評選市場區隔為實證以說明所建議的分析法。In today’s global business environment, market segments selection are criticalmarketing activities of all companies. In order to evaluate and select the appropriate marketsegments, several decision makers and criteria are needed to be involved in the decisionprocess. This study proposes a hybrid fuzzy Quality Function Deployment (QFD) which is acombination of fuzzy QFD, fuzzy Analytic Hierarchy Process (AHP), and fuzzy techniquefor order preference by similarity to ideal solution (TOPSIS) to select the suitable marketsegment.In the proposed approach, fuzzy QFD is used in determining the importance of weightsfor the internal characteristics (WHATs), external criteria relevant to market segmentsassessment (HOWs), and the “HOW”-“WHAT” correlation scores, while fuzzy AHP isapplied to obtain more decisive judgments by prioritizing the market segments selectioncriteria and weighting them in the presence of vagueness. The ratings of alternatives versusqualitative criteria are assessed in linguistic values represented by triangular fuzzy numbers.Then, fuzzy TOPSIS was used to obtain the final ranking of alternative. Finally, an empiricalstudy on rental-car Company is put forward to illustrate the performance of the proposedmethodology which the final solution is obtained by identifying the best market segment forfurther development and negotiation.
