| Abstract: | The authors analyzed the disadvantages of the classical poly-statistics approaches for assessment and proposed the improved GRA (Gray Relevent Analyse) in electric power consumption assessment by applying AHP (Analytic Hierachy Process) in improving the method for calculating related degree. The importance of 12 industry products which influence the electric power consumption was evaluated. The qualitative and quantitative element comprehensively were considered and the different weights to measure the related coefficient were given. The results of evaluation agree with the practical situation. It offers a new method to the market analysts of electric power trade. |
