The satisfaction of teachers and students can be defined by several key indicators, such as measuring teachers' work efficiency, work intensity and round-trip intensity.

Efficiency w= teacher's actual class time/(teacher's bus time+class time+school time).

Then the teacher's satisfaction degree S 1 is the weighted average of several key indicators. Pay attention to the normalization of weighted average of dimensionless quantity and dimensional quantity.

For students, you can define the frequency of each class every week, the frequency of classes every day and so on.

For school satisfaction, we can define the number of bus trips, which is linked to a certain indicator of teachers, the frequency and duration of classroom and multimedia use cycles, and so on.

2. Solve according to the model and data of the first question.

3. Take the satisfaction of teachers, students and schools as indicators.

4. Put forward reasonable suggestions according to the results.
