Abstract: According to the characteristics of the mechanical professional experimental teaching system,combined with the requirements of the excellent engineering education certification,the hierarchical analysis experimental teaching quality.The system designed the experimental teaching quality evaluation index,and transformed the qualitative problem into a combination of qualitative problems,and objectively constructed the judgment matrix of each index.Through the hierarchical total ranking and consistency test,the weighing order of each factor of the indicator layer is obtained.According to the analysis results,the system assigns the four major factors of the college mechanical professional experimental to occupy the weight,and investigates the quality of the experimental teaching.The results show that students and teachers reflect higher.
