Problems solved by technology

In the current automobile field, there is no professional intelligent evaluation system yet. Therefore, users urgently need a unified and clear standard for the evaluation of automobiles, especially used cars, so that there is a unified evaluation system for used cars in the messy automobile market. Ruler, so that the value of the car is no longer dominated by human factors

Embodiment Construction

[0059] Below in conjunction with embodiment, the present invention is described in detail:

[0060] like figure 1 As shown, it is the overall calculation flow chart of the method of the present invention. A smart car evaluation method, comprising the following steps:

[0061] Step 1: Establish an AHP model, which is as follows:

[0062] a1. Classify the factors that affect the value of the car and establish a hierarchical structure model. like figure 2 As shown, the establishment of a hierarchical structure model is to layer the factors contained in the problem, the highest layer is the thing to be evaluated, specifically in the present invention, the value of the car, the second layer is the n factors that affect the value of the car, figure 2 Take 5 elements A1,...,A5 as an example;

[0063] a2. The decision maker uses the pairwise comparison method to compare the relative importance of each influencing factor in the same level with respect to the same factor in the p...

Abstract

The invention relates to the car value evaluation field, in particular to an intelligent car evaluation method and system. The method comprises that a step analysis model and a fuzzy evaluation model are founded, a final newness rate is obtained through an equal difference rating method and matrix operation and the evaluation on second-hand cars is realized. The invention provides a more mature and accurate intelligent car evaluation method and system based on a mathematical intelligent model, i.e. realizes the evaluation on the cars by combining a step analysis method with a fuzzy analysis method. Wherein, the step analysis method obtains weight matrix by founding the step structural model of factors influencing car value. The fuzzy comprehensive evaluation method is a comprehensive evaluation method based on fuzzy mathematics and converts qualitative evaluation into quantitative evaluation according to the membership degree theory of fuzzy mathematics, i.e. an object restricted by various factors is evaluated in the whole with fuzzy mathematics. The invention can solve the fuzzy and difficultly quantized problems well.

Description

1. Technical field [0001] The invention relates to the field of automobile value evaluation. Specifically, it relates to a smart car evaluation method and system. 2. Background technology [0002] The current automobile evaluation methods include the current market price method, the replacement cost method, the comprehensive analysis method and the asset liquidation method. Due to the insufficient development of my country's second-hand car market, it is difficult to obtain market value as a reference, so the most commonly used method is the replacement cost method. Determination of the newness rate is a key issue in this method. At present, the determination of its new generation rate is mainly based on the determination method based on the use time, and the ratio of the number of driving years to the number of driving years is calculated. In practical applications, the prices calculated by the above evaluation methods are not very accurate. Therefore, in the current aut...
