The index information in the control operation efficiency evaluation of the terminal area has the characteristics of difference and non-uniform dimension. Aiming at the traditional principal component analysis method to standardize the data, it will eliminate the shortcomings of the differences between indicators. Based on the improved principal component analysis method and the objectivity of the entropy method, an integrated comprehensive evaluation of the control operation efficiency of the terminal area is proposed. model. The model uses averaging instead of standardized processing index data, and uses SPSS23 software to obtain improved principal component analysis and entropy method to evaluate the ranking results. The two evaluation results are passed through the consistency test to obtain the final comprehensive evaluation value and ranking result of the terminal area control operation efficiency. The results of the calculation example show that the established evaluation model can evaluate the control operation efficiency of the terminal area more efficiently.
