Embodiment Construction

[0049] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] like figure 1 Shown, the present invention comprises the following steps

[0051] 1. Data preparation

[0052] 1 data acquisition

[0053] According to the previous business understanding and business research results, theoretically search for variables related to customer credit, and extract related variable data of the credit evaluation model from the marketing system of the power company and the third-party credit system, mainly including: basic attributes: user number, user classification, Account opening date, account name, address, contact number, certificate information, etc.; payment behavior: electricity fee issue date, actual receipt date, receivable electricity fee, actual electricity fee, actual receipt date, payment method, etc.; electricity usage behavior: breach of contract Electricity history records, illega...

Abstract

The invention provides an electric power credit evaluation method based on big data, and relates to an evaluation method. An existing credit evaluation system only based on a traditional quantitative analysis method cannot meet requirements of an electric power company to dig data value, undertake a customer credit rating system, and realize responsibility of enterprise derivative value at present. The electric power credit evaluation method comprises a data preparation step, an index system construction step, a model construction step, a model verification step and a model output step. According to the technical scheme, systematic cleaning and analysis are performed on a large number of historical data such as customer basic information, payment behavior, electricity using behavior and social credit information, an implicit behavior model and credit characteristics in the data are dug by applying a mathematical statistics method and a BP neural network model improved by genetic algorithm, a relationship between historical information and credit performance is captured, the credit performance is synthetically evaluated by a credit level, classified credit management of electric power customers is advanced, and differentiated arrears collection measure research work is supported and carried out to form a diversified collection strategy.

Description

technical field [0001] The invention relates to an evaluation method, in particular to an electric power credit evaluation method based on big data. Background technique [0002] A scientific and reasonable customer credit evaluation system with a complete range of categories is an important prerequisite for realizing the derived value of power companies. The existing credit evaluation system cannot meet the requirements of power companies to mine the value of data, and undertakes the responsibility of the customer credit rating system to realize the derived value of the enterprise. [0003] In the face of changes in credit evaluation methods, the establishment of a customer credit evaluation system centered on big data mining, combined with traditional quantitative analysis methods, multivariate statistical methods and machine learning evaluation systems, is the foundation for the credit evaluation industry to adapt to high-tech warfare Assure. Therefore, establishing a n...
