Research And Development Of Agricultural Products Logistics Management Information System Based On Distribution Node Location And Path Optimization

With the continuous development of China's agricultural economy and the rapid progress of the logistics industry,the development of agricultural products logistics industry is also changing with each passing day.From going out for shopping to delivering goods home,whether it is logistics,express delivery or takeout,people's happiness in life has been greatly enhanced.At the same time,people have higher requirements for the timeliness of logistics,which also exposes some problems existing in the traditional logistics industry.On the one hand,the process of urban-rural integration is accelerating,and the logistics environment is constantly changing,making it impossible to adapt to the real-time needs of the market;On the other hand,the continuous development of the Internet has encouraged the logistics industry to transform from traditional logistics to smart logistics.Based on the current situation and development trend of modern agricultural product supply chain and logistics network resources,domestic and foreign scholars have made many useful explorations on agricultural product logistics service network,distribution network and resource optimization.In this paper,on the basis of existing research,in view of the new demand for agricultural products logistics industry,this paper analyzes and studies the model and algorithm of logistics distribution node location optimization and path optimization,and on this basis,develops an agricultural product logistics management information system.The specific research results are as follows.(1)Constructed a model for the location of distribution nodes in the agricultural product logistics networkFor the optimization of the location of the distribution node in the agricultural product logistics distribution service network,using quantitative analysis methods,based on minimum cost distribution node location,building the economy,adaptability and global distribution node location model.(2)Constructed an optimization model for the distribution route of agricultural product logistics networkAiming at the distribution path optimization in the agricultural products logistics distribution service network,the VRP and TSP models were constructed by splitting the whole logistics process,and the optimal solution was obtained by using the nearest neighbor algorithm and the saving algorithm.Aiming at the agricultural products distribution path of "agricultural and supermarket connection",an optimization model including time window was built,and an example was verified by the improved genetic algorithm to realize the resource optimization of agricultural products logistics service network.(3)Developed agricultural product logistics management information systemUsing object-oriented software development method and technology in software engineering,based on the software process of analysis,design,implementation and test,developed agricultural product logistics management information system.Firstly,the demand analysis of agricultural products logistics system is carried out by object-oriented analysis method,and the use case diagram and other related analysis models are constructed;Secondly,based on the principles of software design and adopting the design ideas of layering and submodules,a software architecture including the persistence layer,business layer,and presentation layer is constructed;Thirdly,use Spring MVC technology to realize the related functions of each module;Finally,through the code to achieve agricultural logistics management system.By optimizing the location of distribution nodes and distribution paths in the agricultural product logistics service network,the efficiency of the entire service network is effectively improved.Cooperate with the use of agricultural products logistics management information system,make agricultural products logistics more efficient,accurate,timely,convenient,reduce the cost,improve the benefits.
