Abstract

The invention relates to a used car valuation method and system based on an intelligent algorithm. The method first proposes a first-level index and a second-level index for evaluating the performance of a second-hand car, and establishes a relationship between customer demand and the second-level index through a quality analysis house analysis method. relationship, using artificial neural network and big data analysis methods to conduct feedback adjustments to the valuation of used cars, which is more in line with market rules and achieves scientific, efficient and accurate evaluation. The present invention combines the big data analysis method, after the system estimates the valuation of the second-hand car, through big data information comparison, dynamically adjusts the valuation, and clearly and intuitively reflects the situation of the vehicle relative to the overall market situation, so that The valuation system is more intelligent and conforms to the law of market changes.

Description

technical field [0001] The present invention relates to a used car evaluation method and system based on an intelligent algorithm, relates to the application of the intelligent algorithm in the field of used car evaluation, and is a comprehensive evaluation system that comprehensively considers vehicle maintenance information, vehicle basic information, and vehicle use status information. Combining big data analysis and artificial neural network algorithms to achieve accurate evaluation of used car valuations. Background technique [0002] In recent years, my country's vehicle industry has developed vigorously. In 2017, the sales volume of new vehicles reached 24.74 million. The rapid growth of vehicle ownership has led to a large number of used cars flowing into the trading market. In 2000, the national second-hand car sales volume was 250,000, and in 2015, the second-hand car sales volume reached 9.41 million, which was 37.64 times the sales volume of second-hand cars in 2...
