A New Method of Information Aggregation for Multi-type Evaluation Subjects-Involving Teachers’ Performance Evaluation Based on TDW Operator

PP: 901-906
Faming Zhang,
Traditional university teachers’ performance evaluation rarely considers quantitative evaluation, and usually involves only one subject. In order to fill the inadequacies, this paper put forwards a new method to aggregate the evaluation information of university teachers. The new method involves many different parts of the evaluation. First, a new information aggregation method——TDW operator method is presented; then TOPSIS is employed to handle evaluation results of different types of evaluation subjects in order to avoid the difficulty of information aggregation preference of different types; third, method to determine density weighted vector according to the relevant degree of different information is introduced. Finally, an example is given to illustrate the effectiveness.
