City Logistics Distribution Management System Analysis And Design

At present, the "last one kilometer" of city logistics distribution problem is relatively outstanding, because the city of freight vehicles into the core city limits is very strict, so that the logistics efficiency is not high, the high cost of. To construct the reasonable scale, advanced technology, excellent service" last kilometer" logistics and distribution network, forming a unified appearance, identification, the use of information management, for the life of the residents, commercial trade, production enterprises to provide efficient, high-quality logistics services, logistics distribution safety, fast, professional, the scale of, intensive.Based on the logistics and distribution of the actual business processes as the basis, on city logistics distribution center allocation information system needs a careful investigation and analysis, design of the system structure, the system of background database design also made a detailed description and analysis. The logistics distribution decision problems are studied, on the basis of the characteristics of city logistics distribution center, set up logistics distribution decision problem of the general model, and uses the IPO function design to solve. Finally, using the database concepts and logic design, for distribution management system of actual development, and realize some function module.Completed work as follows:1. needs analysis, analysis of the elements of logistics and distribution functions, processes, given the distribution management of overall business processes and order processing, sub-cargo operations, distribution operations, return operations and business processes, data flow diagram expressed system data processing requirements, and gives the order processing, receiving, distribution, vehicle scheduling, the return data flow diagram.2. system design, completed the structural design of the function module division and overall system functionality, refinement of the various functional modules, given the detailed functional structure of each functional module, database ER diagram and database table structure...
