The Graphic Method Study Of Agricultural Products Distribution Center Location

The issue of agriculture is very important to receive attention. Modern agricultural products logistics distribution system provides important guarantee for the development of modern agriculture. Efficient agricultural products logistics distribution system mainly depends on the location of distribution center. To improve the efficiency of distribution center operating indicators, scientific and reasonable scheme has important practical significance.Location problem involves many factors, belongs to the NP problems. Location models and algorithms are mostly very complex, while the evaluation method involves too many human factors. So some scholars use GIS to solve distribution center location auxiliarily to make the site selection process more intuitional. However, the visual process has not solved location optimization by graphic method fundamentally. Therefore in this paper, we study a kind of graphical scheme to solve the large-scale agricultural products distribution center location problem, which includes the following three steps.Division of agricultural products distribution region. According to the research of agricultural products distribution region division and general classified methods, select two dimensional graph theory cluster analysis and agricultural products logistics distribution time window to divide a large-scale agricultural products distribution area into multiple small agricultural products distribution areas.Choose the agricultural products logistics distribution center location by research of graphic method. According to the problem of logistics distribution center location, analyse the principles and factors of distribution center location firstly. Then establish the graphic model of location considering transportation cost and land cost. Finally, find the position of distribution center.There are two distribution center problem discussed in this paper. Known the first distribution center, study the problem of the necessity, location and cost if establish a second distribution center. In the first place, analyse the logistics network scale value to suggest setting up the second distribution center. Then determine the distribution center location model. Finally, compare the cost of two distribution centers with that of single, according to the cost model, to confirm the feasibility of setting up the second center.In the last part, this paper uses the data of Baotou agricultural products logistics to simulate the graphic scheme which validates the feasibility.To solving the problem of a large-scale agricultural products distribution center location, this paper puts forward a graphic scheme with the technology of graph theory cluster analysis and so on. The graphic method which visualizes the complicated problem has some practical value.
