Abstract: To one company, it takes 8 major economic indicators as evaluation indexes. Firstly, it uses correlation method to determine the weight and uses the double-point method to sort the 8-years comprehensive economic enterprises. Then through the analysis of the correlation matrix, it identifies the main factors. Finally, the ranking and principal component analysis results are compared and analyzed.

Abstract: In this paper, using the relevant data of 34 teaching staffs who participate in the academic title evaluation of associate professor in 2010, firstly it introduces the entropy weight method, Topsis method with subjective weight, Topsis method with objective weight and double base points method with subjective weight to evaluate and sort the performance of 34 teaching staffs. Secondly, two combination evaluation models are constructed to do the same work and the conclusions are more science and rational.

Abstract: This paper will focus on the control method of the brake test- bench, we have used physics, theoretical mechanics, numerical methods method and use Matlab software, Excel software to calculated data and drawing. Eventually we establish a mathematical model to control electric current. . The model will help us testing the merits of the brake, and assist us in the design process.
