Good extracurricular activities can optimize the quality of education, fetch up with classroom education and teach them what they cannot learn from it, is conducive to improve students’ comprehensive quality, to complete the task and achieve the goal of university education. For this reason, this paper proposes an extracurricular sports lifestyle evaluation to college students via an improved ELECTRE method. In the proposed method, three indexes – concordance index, non-concordance index and credibility index – are defined first. Based on these indexes, the preference evaluation matrix is constructed, and consistent credibility, non-consistent credibility and net credibility are computed second. Third, it was sorted for the quality of all alternatives according to the value of group net credibility. In general, the greater the value of the group net credibility of a project, the better the project is. Simulation experiments suggest that this proposed method is feasible and valid. Extracurricular activities for college students take a very important part of university education, and it models their characters, opens up their minds, adventure spirits, strengthens their social connections, improve their comprehensive quality and their personal positive socialization.

良好的课外活动可以优化教育质量，掌握课堂教育，教给他们无法学到的东西，有利于提高学生的综合素质，完成任务，达到大学教育的目的。因此，本文提出了一种通过改进的ELECTRE方法对大学生进行课外体育生活方式的评价。该方法首先定义了三个指标：一致性指标，不一致性指标和可信度指标。基于这些指标，构建了偏好评价矩阵，然后计算了一致性可信度，非一致性可信度和净可信度。第三，根据集团净可信度的价值对所有替代产品的质量进行排序。一般来说，一个项目的集团净信誉值越高，该项目就越好。仿真实验表明，该方法是可行和有效的。大学生的课外活动是大学教育的重要组成部分，它塑造了他们的性格，开拓了他们的思维，冒险精神，加强了他们的社会联系，提高了他们的综合素质和个人积极的社会化。
