Embodiment Construction

[0015] like figure 1 As shown, the multi-attribute group decision-making-based user abnormal power consumption and arrears risk assessment method of the present invention includes the following steps:

[0016] Step 1: Establish a customer set based on customer data, and determine the highest priority indicators; obtain user abnormal electricity consumption and payment behavior data, and establish a sub-priority evaluation index system U. The step 1 includes:

[0017] Step 1.1, establish customer set X={X according to customer data 1 ,X 2 ,X 3 ,...,X n};

[0018] Step 1.2. The importance of customers is the most important indicator for abnormal power consumption and the risk of arrears, and the importance of customers U 0 This indicator is designated as the highest priority indicator in the evaluation, with a weight of ω 0 ; According to the amount of electricity consumption and electricity bills of customers, customers are divided into three categories: large customers, ...

Abstract

The invention discloses a user abnormal electricity utilization and arrearage risk assessment method based on a multi-attribute group decision. The method comprises: firstly, determining a most priority index; establishing a secondary priority index system; using an entropy weight method to determine an index weight, using a grey correlation degree and a maximum entropy criterion to determine an expert weight, combining the index weight and the expert weight and then combining with a most priority index weight to obtain a comprehensive weight, finally, using a fuzzy comprehensive evaluation model to evaluate, performing maximum membership ranking on the evaluation, and giving an evaluation result of a user. According to the method, the abnormal electricity utilization and arrearage risks of the user are evaluated, so that a power supply enterprise pays attention to high-risk customers as soon as possible, and the probability of economic loss can be reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power consumption, and relates to a method for assessing abnormal power consumption of users and arrears risk based on multi-attribute group decision-making. Background technique [0002] Electricity is one of the important energy sources in modern society. While providing power resources for the society, power supply enterprises must also ensure the normal operation of the enterprise itself. my country's power marketing model of consumption first and payment later brings certain economic income risks to power supply companies. If the electricity fee cannot be recovered normally, it will seriously affect the efficiency of power supply companies, causing power supply companies to have insufficient funds for turnover, which in turn will affect subsequent power supply. Not only will it bring losses to the enterprise, but it will also bring serious losses to the society and affect the normal developme...
