The analytic hierarchy evaluation and quantitative analysis model are studied in this paper by means of the main idea of analytic hierarchy process. According to the estimate data which were filled by students on network in the second semester in 2008 in CNU, an innovative model Q=W•R is proposed. And based on MATLAB, the model is complemented. According to this model, the teaching qualities of our mathematics department's teachers are analyzed. And some suggestion for reference proposed for the future teaching reform.
