Research And Development Of Chain Logistics Distribution System Based On Node.js And WebGIS

The rapid development of e-commerce and the continuous innovation of the new retail concept have brought huge impact on traditional retail enterprises represented by convenience stores,chain stores.Under the new situation,it is very important for traditional chain retailers to change the development model and actively explore the concept of new retail.As an important part of the daily operation of chain retailers,the stocking logistics not only affects the operating cost and profitability of chain enterprises,but also has an important impact on the overall business development of chain enterprises.Therefore,saving logistics costs and building a scientific and efficient freight distribution system is also one of the important links for chain retailers to explore new business models and enhance their competitiveness!In this thesis,Node.js and WebGIS technology are applied to build a logistics distribution system which integrates product information,order information,warehouse information and vehicle information based on the background of providing logistics decision support for chain stores,supermarkets and other traditional chain retailers.And the main research work and achievements are as follows:(1)Node.js and WebGIS are combined to develop the system.Class libraries such as Mongoose,Coordtransform,Formidable,Esri-leaflet and Express framework,Leaflet map library and ArcGIS Server are combined to develop the GIS system,which provides a set of WebGIS development scheme with practical reference significance.(2)This system uses MongoDB database to store data.According to the actual situation,the spatial data is organized into GeoJSON format with the help of Mongoose class library for storage,and the attribute data is organized into JSON format for storage.The spatial database is no longer set separately,thus realizing a lightweight data storage mode.(3)This system integrates product information,order information,warehouse information and vehicle information through WebGIS platform.It implements functions such as product browsing,order submission,warehouse selection,multi-path distribution,nearest facility query,service area view,distribution path planning and so on.The one-stop logistics distribution system is realized by constructing the order platform for the merchant,the control platform for the supplier and the distribution platform for the driver.
