| 摘 要： | 目前诸多的综合测评方法在权重设置等方面的局限性制约了人们对评价对象的科学认识,本文根据Rough 集理论,提出了基于Rough 集的综合评价方法,旨在消除权重设置的主观性,实现完全数据驱动,不需要人为设置权重.通过大学生综合测评实例,验证该方法的实用性、可行性.

| Abstract: | Although many comprehensive measurement methods have improved objectivity of evaluation process, the limitations in weightassignment and establishment of single factor measurement matrix of these methods restrict us to evaluate objects. In this paper, a new multi-attribute measurement method based on rough set is presented, which eliminates the subjectivity in weight assignment, efficiently reduces the scale of index system and shortens calculating time, realizes completely data driving, not needs set weightiness by manual acting. An example shows this method is effective and feasible. |
