摘要
针对灰色关联分析方法在计算关联度时客观性不足的问题,首先对两种不同的改进方法进行对比研究,通过详细分析,从理论和应用上指出了两种改进方法的优缺点。然后将两种改进方法应用于河北省农村电力消费的评价研究中。实际应用表明,两种改进的方法根据各自特点不同为求解多元分析与评价问题提供了科学可行的方法。
With the objeetive to overcome the lack ofobjeetivity in calculating related degree ofthe Grey Relational Analysis （GRA）, two improved methods are suggested. The advantages and disadvantages of each method are discussed. The two improved methods are applied to the research of evaluating rural electricity consumption of Hebei province. Empirical results indicate that these two improved methods are effective in solving the problems of poly-statistics and assessment.
