↗

The analytic hierarchy process (AHP) is used to determine the weights of various indicators. The paper claims this method has a scientific basis and reduces the influence of subjective factors.

Conditions: Applied to determining weights of various indicators.; Presented as part of the comprehensive evaluation framework.

Meet the concept

↗

The factor set UU is the finite set of nn evaluation factors, and the comment set VV is the finite set of mm possible judgments or grades. Together they define the two domains that the fuzzy relationship matrix maps between.

Conditions: There are two finite domains: the factor set UU and the comment set VV.; UU contains nn factors and VV contains mm comments.

↗

The conclusion claims that compared with previous methods, the proposed evaluation system is more comprehensive because it includes both teachers' teaching factors and the student learning system.

Conditions: Comparison is made with previous methods.; The evaluation system includes teachers' teaching factors.; The evaluation system includes the student learning system.

The paper states that the evaluation results are first normalized to obtain an evaluation result description. Then, the final category is identified according to the principle of membership degree, which yields the label "excellent" for the teacher's performance.

Conditions: The result vectors must first be normalized.; Final identification uses the principle of membership degree.; The displayed example concerns a teacher performance label.

The three vectors correspond to professional ethics (0.48,0.38,0.14)(0.48, 0.38, 0.14), the amount of teaching exercise (0.65,0.26,0.09)(0.65, 0.26, 0.09), and the amount of teaching (0.57,0.30,0.13)(0.57, 0.30, 0.13). These represent the membership degrees or normalized evaluation weights for each indicator.

Conditions: The vectors are displayed as part of the example preceding the conclusion section.; Each component is a decimal between 0 and 1.
