A Group Decision Making Method Based on Meituan Takeaway Shop Selection

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。

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.
