【摘要】：农产品流通的关键是其分销配送网络,它关系着人们日常生活的满足及生活质量的改善。农产品在分销配送过程中表现出的不足已成为阻碍农产品市场繁荣与发展的重要因素。要想改善农产品分销渠道现状,使得农产品的分销配送网络能迅速应对市场的变化,就要大力发展农产品物流,优化农产品的网络结构,提高农产品的市场竞争力和供应链效率。因此,研究如何优化农产品的分销配送网络结构具有重要的理论和现实意义。本文通过分析我国农产品的分销配送网络的现状及其存在的难题,针对这些问题建立了多品种的分销配送网络优化模型,并结合实际案例,解决了基于遗传算法的多品种的两级分销配送网络库存-选址-指派优化问题。本文首先从农产品分销配送网络的相关理论着手,分析总结了农产品分销配送网络的功能、特点、影响因素及需要研究的对象和优化的内容,确定了文章的思路和内容。在此基础上,结合农产品分销配送网络的特性及其存在的问题,对分销网络优化模型中的关键参数及成本进行了详细分析,考虑需求节点不同类产品的来源是否单一,分别建立了确定需求不考虑库存策略的单源和多源分销配送网络模型。接着结合实际及市场环境对建立的模型进一步研究,考虑随机需求情况下节点的库存订货策略,建立了上述两种方式下考虑库存策略的农产品的分销配送网络优化数学模型,确定被选分销中心数量、位置及其分配任务,制定各分销中心和需求点的最优订货策略,使得整个分销系统总成本最低。模型综合考虑了农产品在分销过程中的碳排放成本、变质损耗、库存成本、客户满意度、分销中心绩效、成本折旧等因素,更具实用性。最后针对湖北省特色果蔬产品分销配送实际情况建立单源配送优化模型,基于遗传算法思想设计算法程序并利用MATLAB编程求解,得出网络各节点的订货量订货点、指派关系及备选分销中心的数量和位置。本文的研究不仅优化和完善农产品的分销配送体系提供一定的参考价值,而且对农产品物流企业优化其网络布局时具有一定借鉴作用。
[Abstract]:The key to the circulation of agricultural products is its distribution and distribution network. It relates to the satisfaction of people's daily life and the improvement of the quality of life. The deficiency of agricultural products in the distribution and distribution process has become an important factor hindering the prosperity and development of agricultural products market. The status quo. So that the distribution and distribution network of agricultural products can quickly respond to market changes, we should vigorously develop agricultural logistics, optimize the network structure of agricultural products, improve the market competitiveness of agricultural products and supply chain efficiency. It is of great theoretical and practical significance to study how to optimize the distribution and distribution network structure of agricultural products. To solve these problems, a multi-variety distribution network optimization model is established, and combined with practical cases. The optimization problem of inventory location assignment is solved based on genetic algorithm. Firstly this paper starts with the related theory of distribution and distribution network of agricultural products. This paper analyzes and summarizes the function, characteristics, influencing factors, research objects and optimization contents of the distribution network of agricultural products, and determines the ideas and contents of the article. Combined with the characteristics of distribution network of agricultural products and its problems, the key parameters and costs in the optimization model of distribution network are analyzed in detail, considering whether the source of different types of products in the demand node is single or not. The single-source and multi-source distribution network models are established to determine the demand without considering the inventory strategy, and then the model is further studied in combination with the actual and market environment. Considering the inventory ordering strategy of nodes under random demand, the optimal mathematical model of distribution and distribution network of agricultural products considering inventory strategy is established, and the number of selected distribution centers is determined. The location and assignment, the optimal ordering strategy for each distribution center and demand point, makes the total cost of the whole distribution system the lowest. The model considers the carbon emission cost and deterioration loss of agricultural products in the distribution process. Inventory cost, customer satisfaction, distribution center performance, cost depreciation and other factors are more practical. Finally, a single source distribution optimization model is established for Hubei province. The algorithm program is designed based on the idea of genetic algorithm and solved by MATLAB programming, and the ordering points of each node in the network are obtained. Assignment relationship and the number and location of alternative distribution centers. The research in this paper not only provides some reference value to optimize and perfect the distribution and distribution system of agricultural products. And to optimize the distribution of agricultural products logistics enterprises when the network has a certain reference.
