Comprehensive Credit Evaluation Model of Electricity Customer Based on the Changing Trend of Credit

In order to solve the credit quantification and scoring problem, this paper did some research on credit evaluation model of electricity customers. The credit was divided into 5 first-grade indicators and 15 second-grade indicators. The paper quantified these indicators and evaluated their weights by utilizing Analytic Hierarchy Process model. The indicators were scored by utilizing exponential scoring. According to the weight and scores of each indicator, we calculated the month credit values of the last 12 months. Through these month credit values and their changing trend, the comprehensive credit was calculated. We used a customer sample data to verify and analyze the model. The experimental result shows that the model can evaluate credit indicators reasonably and effectively. Thus, the credit quantification and scoring problem is solved.
