Research on the Identified Assessment Model of Used Car Based on AHP Algorithm

In the used car market, residue ratio of accuracy directly affects the accuracy of the used car's price.Therefore, it is an urgent that calculation method is a scientific, accurate and easy to operate. Based on the existing estimation methods , improvements used car residue ratio have been made.It considers the various factors that affect the second-hand cars residue ratio, borrowed ideas of AHP, and the use of MATLAB software for weight analysis, simplify complex the calculation process, so calculation of residue ratio is both scientific and simple, so that it is widely used.
