| The combination of online and offline "Internet plus" transport has now become the main mode of intra city express transport.Among them,small and medium-sized merchants have a more frequent demand for goods transportation.The mainstream local express platforms mainly provide general services for individual users,but have low attention to small and medium-sized merchants,lack targeted prices,and limited discounts and payment methods.Therefore,establishing a dedicated local express platform for small and medium-sized merchants can save on transportation costs and lower transportation prices.This article designs and implements a local express platform consisting of a client,employee,and management end to meet the business process requirements of customers placing orders,picking up items by pickup personnel,sorting personnel entering the wauniapprehouse,and driver delivery.The backend of the system mainly adopts SpringBoot+JPA framework technology,while the client and employee end adopt front-end technology based on the framework.The system provides customers with the function of placing orders and solves the problem of single payment methods by providing three payment methods,including wallet payment,to achieve order payment;We provide reasonable price calculation and discount methods for the needs of small and medium-sized merchants and price analysis based on prior knowledge.The system adopts the BCrypt algorithm to encrypt employees’ login passwords,and provides job seekers with synchronized object lock technology based order grabbing functions and Bluetooth connection to printers and other job related functions;Provide functions such as order sorting and outbound,itinerary creation,and departure for sorters and drivers.The management end adopts front-end framework technology based on Vue+Element UI,and integrates Echarts technology to achieve chart display of order and amount data.It implements a management information system with functions such as order management,financial management,and basic management,as well as one-dimensional PNG files,two-dimensional PDF files,statistical data Excel file download function,and visualization of area division and order distribution based on map components.Secondly,in order to solve the problem of difficulty in sorting too many goods,a method of area division and route setting was implemented to complete the division of delivery areas and the setting of delivery routes,which improved the efficiency of sorting personnel in sorting goods;To address the issues of high delivery costs,low delivery efficiency,and low service levels,an order clustering partitioning method based on DBSCAN algorithm was adopted to determine the number of delivery vehicles and achieve order classification loading,thereby avoiding repeated regional transportation by multiple drivers.An improved genetic algorithm based path planning method was proposed to optimize the driver’s delivery path,saving time by shortening the delivery distance.In March 2022,the platform was successfully released into three software versions on the B/S and mini program platforms and used in the Jinan area,achieving good results.As of March 2023,there are currently over 10000 registered users,with approximately 4000 active users per month except during the epidemic period.The average monthly order revenue is about 160000 yuan,and customers have accumulated a recharge of about 350000 yuan.The total cumulative flow of orders and recharge is about 2 million yuan,with an average daily order volume of 500 and a cumulative delivery of about 130000 orders.There are over 30 warehouse stations and more than 70 transportation vehicles,covering various regions of the city. |
