【摘要】：中央连续几年把解决好“三农”问题作为重要的工作问题，，现代的农产品物流配送体系为发展现代农业提供重要保障。高效的农产品物流配送体系主要取决于配送中心的选址问题，科学合理的选址方案对提高配送中心各项运营指标效率具有重要的现实意义。选址问题涉及很多因素，属于NP问题，选址的模型算法大多非常复杂，而其他的评价方法人为因素过多，因此有部分学者将GIS引用到配送中心选址中，使选址过程更加直观，但这种可视化的过程并未从根本上将图解运用到选址优化中。因此本文研究一种图解选址方案来解决大规模多农产品配送中心的选址问题，包括以下三个步骤： (1)农产品配送区域划分。研究农产品配送区域划分基本问题及配送区域划分一般方法，选择两维图论聚类方法并结合农产品物流配送时间窗，将一个大规模农产品配送区域划分为多个小规模农产品配送区域； (2)研究图解方法，选择各农产品物流配送中心位置。针对配送中心选址问题,首先分析概括选址的原则和影响因素，综合运输成本和土地成本，建立配送中心选址图解模型，得出成本最小位置。从而初始确定各小规模农产品配送区域的配送中心位置； (3)存在两配送中心问题探讨。由于物流节点的增加有可能会提升物流网络规模和价值，提高经济效益，因此针对各小规模农产品配送区域，探讨是否存在两配送中心问题。首先分析物流网络规模和网络价值，提出两中心探讨的必要性；然后运用竞争条件下物流中心确定模型，确定第二个配送中心位置；最后构建成本模型，将单配送中心和两配送中心下发生的成本情况进行对比，验证两个中心是否可能存在。最终确定规划区域内，农产品配送中心的数量和位置。最后，论文运用包头市农产品物流数据对该图解选址方案进行实例模拟，验证方案的可行性。论文研究旨在针对大规模多农产品配送中心的选址问题，运用图论聚类等技术，提出一种农产品物流配送中心图解的选址方案，使配送中心选址更加直观，为农产品物流网络规划提供新的方法，具有一定的理论意义和实践指导作用。
[Abstract]:For several years in a row, the Central Committee has taken the "three agricultural" issues as an important work issue. Modern agricultural product logistics distribution system provides an important guarantee for the development of modern agriculture. Efficient agricultural product logistics distribution system mainly depends on the location of distribution center. The scientific and reasonable location scheme has important practical significance to improve the efficiency of the operation index of distribution center. The location problem involves many factors, which belongs to NP problem, and the model algorithm of location selection is very complex. However, there are too many artificial factors in other evaluation methods, so some scholars quote GIS into the location of distribution center, which makes the location process more intuitive. However, this visualization process has not been fundamentally applied to the location optimization. Therefore, this paper studies a graphical location scheme to solve the location problem of large scale multi-farm product distribution center. This consists of the following three steps: This paper studies the basic problems of agricultural product distribution region division and the general method of distribution area division, selects the two-dimension graph theory clustering method and combines with the time window of agricultural product logistics distribution. A large-scale agricultural product distribution area is divided into a plurality of small-scale agricultural product distribution areas; 2) study the graphic method and choose the location of the distribution center of agricultural products. In view of the location problem of distribution center, firstly analyze the principles and influencing factors of the location, comprehensive transportation cost and land cost. The location diagram model of distribution center is established, and the location of the distribution center of each small agricultural product distribution area is initially determined. Because the increase of logistics node may enhance the scale and value of logistics network and increase economic benefit, so the distribution area of small scale agricultural products is aimed at. This paper discusses whether there are two distribution centers. Firstly, it analyzes the scale and value of logistics network, and puts forward the necessity of discussing the two centers. Then the location of the second distribution center is determined by using the model of the logistics center under the competitive condition. Finally, the cost model is constructed to compare the cost situation between the single distribution center and the two distribution centers, to verify whether the two centers are likely to exist, and finally determine the planning area. The number and location of distribution centers for agricultural products. Finally, the paper uses Baotou agricultural product logistics data to simulate the schematic location selection scheme and verify the feasibility of the scheme. The purpose of this paper is to put forward a graphic location scheme for distribution center of agricultural products by means of graph theory clustering and so on, in order to make the location of distribution center more intuitionistic. To provide a new method for the planning of agricultural products logistics network, it has certain theoretical significance and practical guidance.
