Second-hand car pricing optimization method and system

[0042] refer to figure 1 , the present invention provides a kind of used car pricing optimization method, comprising the following steps:

[0043] S11. Obtain the model information of the used car to be priced input by the user;

[0044] S12. According to the input vehicle model information, a valuation model is used to calculate and obtain the valuation of the used car;

[0045] S13. Select the corresponding objective function from the objective function library, and after obtaining the boundary conditions of the objective function input by the user, perform optimization calculations according to the set optimization algorithm and the estimated value obtained through calculation, and calculate and obtain the maximum objective function that maximizes the objective function. The best price is priced as a used car.

[0046] The independent variable of the objective function is the price of the used car. After obtaining the valuation of the used car through calculation, the valuat

[0084] This embodiment is a detailed example of Embodiment 1. In this embodiment, after obtaining the valuation of the used car through calculation, the optimized pricing of the used car is obtained by combining the calculation of the objective function, which specifically includes the following steps:

[0085] Step 1, obtain the model information of the used car to be valued input by the user as follows:

[0086] Model: Beijing Benz C-Class 2013 C 260CGI fashion model;

[0087] Location: Guangzhou;

[0088] Mileage: 47,000 kilometers;

[0089] Listing time: April 2014;

[0090] Usage: non-operating;

[0091] color: White;

[0092] Car condition: excellent;

[0093] Transaction type: used car dealer retail;

[0094] Number of transfers: 2;

[0095] Valuation time: March 2017;

[0096] Step 2, combined with the preset model database, retrieve and obtain the important vehicle configuration information of the used car:

[0097] Displacement: 1.8;

[0098] Horsepower: 156;

[0145] refer to image 3 , a second-hand car pricing optimization system, including a storage medium 100 and a processor 200, the storage medium 100 stores at least one instruction, and the processor 200 is used to load the at least one instruction, thereby performing the following steps:

[0146] S11. Obtain the model information of the used car to be priced input by the user;

[0147] S12. According to the input vehicle model information, a valuation model is used to calculate and obtain the valuation of the used car;

[0148] S13. Select the corresponding objective function from the objective function library, and after obtaining the boundary conditions of the objective function input by the user, perform optimization calculations according to the set optimization algorithm and the estimated value obtained through calculation, and calculate and obtain the maximum objective function that maximizes the objective function. The best price is priced as a used car.
