Research On Location Of Distribution Center Of A Supermarket Chain Based On GIS System

Nowadays,in the mining of profit,resources and human resources have been mature and perfect in the two fields.Under this background,as the "third profit source" logistics area,more and more attention has been paid to the research of social sectors in improving the efficiency and reducing the cost.Because of its special chain supermarket chain business model,the logistics system of its normal business development has a very important significance,and the distribution is the key link in the logistics system,the location problem is priority among priorities,rationality directly affects the location mode to the whole logistics system can operate efficiently,is the focus of logistics theoretical study on.GIS system through the comprehensive processing of spatial data and attribute information,good logistics disciplines and geography together,with the aid of the GIS system equipped on the massive computer data processing and integration of information visualization technology provides a convenient and powerful geographic information processing interface for users,as a powerful tool to assist logistics location analysis,used more and more frequently to the distribution center location applications to effectively promote the development of theoretical research in the field of logistics.This paper firstly introduces the related concepts and the distribution center of chain supermarkets,meaning,and lists the location model of the related concepts and the location of the classic,prepare the theories related to the location of the study,and expounds the definition of the GIS system,and through the application of GIS function is introduced,analyzed using GIS in the logistics center location problem based on the research on the advantages of the combination of the two on the analysis of GIS location system ideas and steps on the model in the optimization,using the GISMAP software and plug-in to map vector data,raster data analysis and processing functions,as an auxiliary tool to participate in the construction of mathematical model,which provides need scientific and quantifiable locations and the data model for regional.In order to better illustrate a point,finally to Shijiazhuang city A supermarket as an example to construct mathematical model using P-median method,using GISMAP software as a tool,the A supermarket distribution center location to provide solutions,and to determine the location of the distribution center can meet the lowest cost of all supermarket distribution demand.
