# 基于熵权理论与灰色定权聚类法的企业电力能效评估模型研究与应用The Research and Application of Enterprise Power Efficiency Evaluation Model Based on Entropy Weight Theory and Grey Fixed-Weight Clustering Method

Abstract: By using the enterprise power efficiency evaluation model based on entropy theory and grey fixed-weight clustering method, this article studies and applies a method of enterprise power efficiency evaluation. Firstly the author analyzes the process of how the index weight of power efficiency evaluation model is established, and then analyzes the process of modeling the comprehensive power efficiency evaluation based on grey fixed-weight clustering method. Accordingly, a method to systematically evaluate the enterprise power efficiency is established. This method not only has scientifically dealt with the problem—subjective judgment in the process of quantifying the index weight, but also makes full use of the index data of the existing objective information and the implicit grey characteristics to maximize the enterprise clustering coefficient. Meanwhile, this method can also comprehensively process the various indexes, and figure out the precise power efficiency of each enterprise to provide a good basis of saving energy and reducing consumption for the enterprise evaluated. Finally, this article, taking the evaluative object of three companies as basis, models and analyzes these three companies’ power efficiency, and verifies the feasibility of the method.
