Problems solved by technology

The traditional transportation and circulation of agricultural products can no longer satisfy the modern agricultural product market, nor can it satisfy the people's pursuit of the quality of agricultural products
[0004] The rapid development of cold chain logistics caters to people's growing demand for products such as eggs, milk, fresh products, fruits and vegetables. However, as far as the inventor knows, the existing cold chain logistics demand forecasting lacks a reasonable forecasting method, and the forecasting results are inaccurate , cannot effectively guide the production and development of the logistics industry, especially cannot scientifically and rationally solve the problem of location selection of logistics nodes for cold chain logistics of agricultural products and the problem of scale optimization of existing logistics nodes

Abstract

The invention discloses a logistics node layout optimization method and system based on agricultural product cold-chain logistics demands. The method comprises steps of carrying out the variable screening of the obtained agricultural product cold-chain logistics basic data in a historical time range of a to-be-predicted region, and screening a plurality of variables; predicting each variable to obtain predicted values of all the variables; obtaining a first agricultural product cold-chain logistics demand prediction value based on all variable prediction values and the multiple linear regression model; obtaining a second agricultural product cold-chain logistics demand prediction value based on all variable prediction values and a pre-trained BP neural network; performing weighted summation on the first agricultural product cold-chain logistics demand prediction value and the second agricultural product cold-chain logistics demand prediction value to obtain a final agricultural productcold-chain logistics demand prediction value; and based on the final agricultural product cold-chain logistics demand prediction value of the to-be-predicted area, the scale of the existing logisticsnode and the distance between the existing logistics node and the to-be-predicted area, obtaining a scale optimization scheme of the logistics node.

Description

technical field [0001] The present application relates to the technical field of logistics demand forecasting, in particular to a logistics node layout optimization method and system based on cold chain logistics demand of agricultural products. Background technique [0002] The statements in this section merely mention the background art related to this application, and do not necessarily constitute the prior art. [0003] In today's 21st century, changes in people's ideas and a prosperous market economy have gradually promoted a new agricultural product circulation system. An agricultural product market that focuses on high-quality agricultural products, efficient agricultural product transportation, and benign economies of scale has gradually formed. The traditional transportation and circulation of agricultural products can no longer satisfy the modern agricultural product market, nor can it satisfy the people's pursuit of the quality of agricultural products.
