摘要
分析了经典多元统计分析方法用于评价问题的缺点,并且运用层次分析法对原有的关联度计算公式进行了改进,提出了电力消费影响因素评价的改进灰色关联分析方法。采用层次分析法对影响电力消费的12种主要工业产品的重要性进行了评价,综合考虑了定性和定量因素,给出了关联系数的重要性权数,使得评价结果更符合实际情况。从理论和实例上说明了该方法的优点。该方法为电力行业的市场分析人员提供了一种实用性强,并且容易掌握的新方法。
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.
