Abstract

The use of mathematical evaluation model is more and more widely, including the comprehensive evaluation of college coaches. In this paper, we build DHGF model using the Delphi method, AHP, Gray Relation and Fuzzy Judgment to evaluate college couches quantitatively. Based on DHGF model, we analyze the influence of timeline on the scores of evaluation indexes, get Plus Function, so as to adjust experts score. So we get dynamic DHGF evaluation model. Then, we apply the model to men's college basketball matches. After that, we discuss that this model is applicable for choosing the best college coach or coaches (past or present) from among either male or female coaches in all sports fields. And we will apply the model to evaluation problems with large time span or with many affecting factors.
