素食店選擇模型體系的提出，是結合顧客學優質服務品質的實際，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VIKOR之資訊處理的群決策方法。該方法的概念對語言評價資訊進行處理和運算，並依據傳統分析方法的基本思想，通過計算備選方案對正理想方案和負理想方案值，進而計算備選方案對正理想方案相對貼近度，最終確定最優方案。由於在該模式中採用二元對比法和熵權法確定指標的加法組合權重，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素食店中的應用，得出其素食店的優質商店的優劣排序，為顧客選擇理想的素食店,提高評價結果的準確性。

A new method is proposed to solve multiple attribute group decision making problems with VIKOR assessment information. The paper developed the selection of evaluation index system for vegan industry model is put forward based on guestology, and a multi-level model of modified ideal solution, based on linear combined binary contrast with entropy weight. According to the traditional ideas method, the optimal alternative(s) is determined by calculating the every alternative and positive ideal solution and negative ideal solution. It is based on the concept that the optimal alternative should have the largest degree of relative closeness from positive ideal solution. 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.
