基于灰色粗糙集的能源消费量综合评价与分析

Comprehensive Evaluation and Analysis of Energy Consumption Based on Gray Rough Sets

在综合评价时,权重的确定直接影响到评价结果的准确性和科学性.为此,基于灰色粗糙集提出了一种新的综合评价赋权数的方法,使得权系数既易于解释,又更加客观准确.进而对华东地区六省一市的能源消费量进行了综合分析,得出六省一市的能源消费量的排名,可以为相关部门在能源分配方面提供一定的参考.

In the comprehensive evaluation, the allocation of weights affects directly the accuracy and scientificity of evaluation results. Based on gray rough sets, a new method of determining weight in comprehensive evaluation is put forward in this paper, making the weight coefficient is easy to explain, and more objective and accurate. Energy consumption of East China is analyzed, obtaining comprehensive place for energy consumption of six provinces and one city in East China, and providing some suggestions for energy distribution.
