Research On Optimization Of Cold Chain Logistics Distribution Routing Of Agricultural Products Under Internet Of Things

The rapid development of mobile communication technologies and Internet of Things technology has made many agricultural product sales companies and logistics industries pay attention to the informationized operation of agricultural product circulation.Due to the characteristics of perishable,perishable and easily dehydrated agricultural product,the requirements for delivery service time are particularly high.Refrigerated transport can effectively improve the phenomenon of farm produce corruption in the process of distribution and transportation.Some developed countries in Europe and the United States,due to the use of advanced science and technology,generally adopt cold storage and transport of their perishable products,and their transport quality is as high as 95%.In contrast,China's cold-chain logistics market is still immature and is in an initial stage of exploration.Because most of the distribution vehicles in the process of logistics distribution are not equipped with refrigeration equipment and do not pay much attention to the protection of agricultural products,they are in transit or arrive After the discovery of the land,many agricultural products have deteriorated.It can be seen that the most important reason affecting the quality of agricultural products is the low-temperature environment.In order to ensure the freshness and quality of agricultural products,it is necessary to complete the logistics distribution process of agricultural products as soon as possible through reasonable low-temperature control and adoption of Internet of Things technology,so as to extend the shelf life of products and ensure their quality.The Internet of Things technology will certainly bring intelligent operation of agricultural products circulation.It will bring easy and easy working methods to logistics workers,and it will also win a good reputation for agricultural products enterprises.The most important thing is that it can greatly improve the level of consumer satisfaction.This article focuses on the exploration and analysis of China's traditional logistics distribution model for agricultural products,and finds out the problems that exist in circulation.To solve the specific problems,the operation mode of using Io T technology in the operation of cold chain logistics of agricultural products was introduced,and the advantages of using IoT technology in the production,processing,packaging,storage and sales of agricultural products were analyzed in depth.Based on this,considering the advantages of IoT technology and the characteristics of agricultural cold-chain logistics,we will study specific path optimization problems in cold-chain logistics.By analyzing the various costs incurred in distribution: fixed costs for delivery vehicles,fuel consumption costs,refrigeration costs,time penalty costs,and the use of IoT technology.Among them,the membership function of customer satisfaction and the loss function of agricultural products are introduced to establish a multi-objective model for the optimization of agricultural product cold chain logistics distribution path under the Internet of Things.In addition,the commonly used genetic algorithms for solving VRP problems are introduced,and algorithm design and program design are performed for specific models.Finally,a logistics distribution example for fresh fruits and vegetables is designed,an algorithm is used to solve the model,and finally the optimal solution corresponds to the most Best delivery plan.The article profoundly analyzes the cold chain logistics distribution model of agricultural products under the Internet of Things environment,deepens the overall understanding of the application of the Internet of Things in agriculture,and at the same time points out the direction for future research on the mode of circulation of agricultural products.
