Abstract

The invention relates to an intelligent selection method of a target parking lot based on gray correlation analysis, comprising the following steps: step S1, constructing a reference number sequence of gray correlation analysis; Step S2, constructing an evaluation sequence of the gray correlation analysis; S3, carry out initial value processing on that reference numb sequence and the evaluation number sequence to obtain the processed reference numb sequence and the evaluation number sequence; S4, calculate that correlation coefficient according to the process evaluation sequence; Step S5, determining the weights of each evaluation index in the processed evaluation sequence, and performing normalization treatment; Step S6, calculating the correlation degree of the processed reference numbersequence and the evaluation number sequence according to the obtained correlation coefficient; Step S7, sorting the calculated correlation degree from large to small to obtain the gray correlation order, and the evaluation sequence with the largest correlation degree corresponds to the optimal target parking lot. The invention is based on the gray correlation analysis, and has more comprehensiveinfluence factors on the selection of the target parking lot, higher intelligence level, more convenient use and higher accuracy.

Description

technical field [0001] The invention relates to an intelligent selection method of a target parking lot based on gray relational analysis. Background technique [0002] As the number of cars increases year by year, urban parking becomes more and more difficult. Even if the scale of the parking lot expands year by year, it still cannot fundamentally alleviate the pressure of parking difficulties. Intelligent parking system is an effective way to relieve parking pressure. Beijing, Shanghai, Hangzhou and other major domestic cities have launched parking space reservation systems one after another, which has greatly improved the utilization rate of parking spaces and brought great convenience to car owners. Contents of the invention [0003] In view of this, the object of the present invention is to provide an intelligent selection method of a target parking lot based on gray relational analysis, which takes into account more comprehensive factors affecting the selection of a...
