Electric customer credit-rating based on entropy and Newton's law of cooling

Comprehensive evaluation of electric power customers' credit situation and the trend is essential to curb the credit crisis. In this paper, a scientific method for electric customer credit-rating is proposed. Firstly, integrate the credit indicators into four dimensions: basic credit, past credit, inherent attribute, and adjustment factor. Secondly, Entropy Weight is adopted to set indicator weight for basic credit. Based on Newton's law of cooling, the impact of past credit is related to the attenuation coefficient. And analytic hierarchy process is used for evaluation of electric customers' inherent attribute, Finally, comprehensive evaluation of the four dimensions, calculate composite score and correspondence level. Experimental results demonstrate that the proposed method realizes the fusion of customer data features and characteristics of the electric power business, and it is an objective and comprehensive embodiment of electric power customers' credit standing.
