結合顧客學優質服務品質的實際，提出咖啡店選擇的指標體系，針對解決具有語言評價資訊的多屬性群決策問題，提出了一種基於SPA之資訊處理的群決策方法。集對分析理論是一種較新的軟計算方法，可有效地分析和處理不確定資訊。近年來，該理論日益受到學術界的重視，已經在決策、預測、資料融合、不確定性推理、產品設計、網路計畫、綜合評價等領域得到較為成功的應用。由於在該模式中採用AHP法和熵權法確定指標的組合權重，兼顧主客觀賦權優點，從而避免了確定低層次多因素權重的主觀性。通過將該模式顧客在選擇咖啡店中的應用，得出其咖啡店的優質商店的優劣排序，為顧客選擇理想的咖啡店,提高評價結果的準確性。

A new method is proposed to solve multiple attribute group decision making problems with SPA assessment information. Set pair analysis(SPA) theory is a relatively new soft computing tool to deal with vagueness and uncertainty．It has attracted much attention of researchers. SPA has been applied to many areas successfully including decision making, forecasting, data fusion, uncertainty reasoning, product design, network planning, and comprehensive evaluation, etc. Finally, it also intend to utilize quantitive method for analysis to improve the order preference of coffee industry selection was attained, and the excellent and ideal coffee industry was ascertained for the guest operation assessment being more objective, reasonable and comprehensive.
