Abstract: With the increasing pace of people's life, take-away has become an indispensable part of people's life. The Meituan take-away platform has become the dominator of O2O take-away platforms that has been widely accepted and used by the majority of people. In a real life, we are often confused by such kind of problems: there are several nearly identical restaurants, and we have never been there before. Which one should I choose to order the meal? Firstly, based on the results of the survey, the index factors are determined and their weights are calculated. Secondly, a multi-criteria group decision model is established by giving the method of constructing an interval multiplicative reciprocal matrix for solving this problem. Finally, a case is studied to illustrate the applicability of the proposed method.

摘要： 随着人们生活节奏的不断加快,外卖成为人们生活中不可或缺的一部分。美团外卖作为O2O外卖平台的一个引领者,被大家普遍认可并得到广泛使用。在生活中,我们经常会为这样的问题而纠结:有几家同类型的店铺,似乎差异不大且都未消费过,该选哪家订外卖呢？首先,本文基于问卷调查的结果,确定了指标因素并计算出其权重。其次,给出构建区间互反判断矩阵的方法,从而建立了一个多准则群体决策模型。最后,通过实例分析了方法的适用性。
