The Research And Development Of Agricultural Materials Chain Supermarkets Distribution System Based On GIS

With the continuous development of domestic economy, chain operation is a kind of innovation in the commercial system, and chain operation has been widely used in many industries such as restaurants, service, agricultural materials. Chain supermarket will become a developing trend of retailing, and distribution is the basic guarantee of supermarket chain development.The chain supermarket can be very good survival and development depending on the operating condition of the distribution system. Designing a more perfect distribution system, improving the delivery efficiency and reducing the distribution cost are an important means of promoting supermarket chain competition. Because distribution is the most key problem in the path optimization problems, the reducing distribution costs is the same as the the optimal path.The main studies of this paper is the distribution problem of ZhengLin agricultural company, agricultural materials chain supermarkets is mainly operating chemical fertilizers, pesticides, agricultural films, such as seed and feed for the supplies of agricultural production,and agricultural materials company provide a unified,rapid agricultural materials distribution service for agricultural materials chain supermarkets distributed across the country, which is an urgent problem to solve for the company[1].To solve the problem of path optimization in the distribution system, which need to introduce in GIS technology. First of all, this paper expounds the related concepts distribution, characteristics and functions of GIS and the their development process, finding that the specific properties of GIS has a great effect on the distribution. Second, the paper expounds the application of GIS in distribution, and in ArcGIS software establishing a point, the map layer,creating network data set to generate road network. Finally, using the characteristics of spatial data, GIS system based on optimal distribution algorithm combine the established road network to carry out the road plan between any two distribution points and realize the choice of optimization route.
