Research On Logistics Information Service Mode Based On Cloud GIS And The Optimization Of Logistics Route

With the development of geographic information industry,more and more logistics enterprises run logistics business with GIS service.But the highly degree of specialization and expensive price of the software and hardware in GIS system have hindered the development of GIS in the logistics enterprises.Cloud GIS is a new kind of geographic information service technology,it can integrate GIS software and hardware resources which are made up on different basement as virtualization service,and then released as a public service in the cloud platform.The user can pay for services on cloud platform according to their own requirement.This service mode can reduce the cost of using GIS services effectively,and users access to the frontal GIS services more convenient.The paper uses OpenStack and GeoServer to design the cloud GIS platform,and uses Python with Djangon framework and MySQL database to develop the logistics information management system.The main research works:(1)Research of logistics route model optimization algorithm,to solve VRP,analysis the process and efficiency of ant colony optimization and improved clonal selection algorithm on solving VRP and experimental comparison and analysis are carried out using simulation data.(2)Design the spatial database of logistics information management system of,and use GIS technology to optimize the VRP solving process,Combining space and attribute information of Logistics user nodes and the basic logistics road network to build logistics distribution network diagram(3)Design and build cloud GIS platform,logistics information management system is developed on this platform,and realize the function of logistics information service including order inquiry,vehicle inquiry,maps browsing,the logistics route planning,etc.The paper proceeds from the actual demand of logistics enterprises for GIS services,study the logistics information service pattern in cloud GIS and distribution of path optimization based on cloud computing and GIS technology,aims to make a beneficial attempt to logistics industry comprehensive information.
