【摘要】：21世纪以来，随着中国市场经济的腾飞与人均可支配收入的提高，广大消费者对生活品质和绿色健康食品的热衷程度也随之提高。人们对农产品的需求不再只单纯地追求“温饱”有无的问题，而是向要求健康化的基础上呈现多样化和差异化方向发展。然而，在国内消费市场对果蔬类、冷鲜肉类等时效性农产品的需求进一步提高的同时，与之相配套的冷链配送物流发展现状却不容乐观，时效性农产品相关理论研究与社会实践需要出现了步调不一致的现象，本文的选题正是在此情况下选定的。本文首先回顾和总结了论文所涉及的时效性农产品、冷藏供应链、物流设施及选址问题的研究成果，并在充分肯定相关学者的努力和研究成果的基础上，，指出针对时效性农产品冷链选址规划问题仍需要进一步深入探讨的地方。接下来，论文对所涉及的三大核心概念及理论进行了逐一论述，即时效性农产品、冷藏供应链、配送中心。论文先构建了一般非时效性农产品配送中心选址模型，这样做的目的是为使得论文研究内容具有可比性和为使主体更加突出。以此作为铺垫，结合时效性农产品自然特性及其对配送流通过程中的特殊要求，引入与时效性农产品流通过程密切相关的腐坏货损、冷藏车制冷能耗及顾客满意度(对运输配送时间的要求)等相关概念。在对三级两阶段冷链综合成本进行分析的基础之上，探索更符合时效性农产品流通特性的混合整数非线性选址模型。在论文最后一部分，以北京市新发地有限公司葡萄配送作为模型的实际算例，使用LINGO对论文构建的选址模型进行求解分析，验证了本文兼顾完整冷链和时效特性的农产品选址规划具有冷链综合成本低的优点。
[Abstract]:Since 21th century, with the rapid development of China's market economy and the increase of per capita disposable income, Consumers' interest in quality of life and green and healthy food has also increased, and people's demand for agricultural products is no longer simply a question of whether or not to have enough to eat and clothe. However, while the demand for fruits and vegetables, cold meat and other time-efficient agricultural products in the domestic consumer market has further increased, The current situation of cold chain distribution logistics is not optimistic, and the theory of timely agricultural products and social practice needs to appear the phenomenon of inconsistent pace, this topic is chosen in this case. Firstly, this paper reviews and summarizes the research results of time-efficient agricultural products, refrigerated supply chain, logistics facilities and location, and on the basis of fully affirming the efforts and research results of relevant scholars. The paper points out that the problem of cold chain location planning for agricultural products needs to be further discussed. Then, the paper discusses the three core concepts and theories one by one, that is, time-efficient agricultural products, refrigerated supply chain, distribution center. The purpose of this is to make the research content comparable and to make the main body more prominent. It is used as a cushion to combine the natural characteristics of timely agricultural products and their special requirements in the process of distribution and circulation. Based on the analysis of the comprehensive cost of the three-stage two-stage cold chain, the related concepts such as degenerate goods loss, refrigeration energy consumption and customer satisfaction (the requirement of transportation delivery time), which are closely related to the circulation process of time-efficient agricultural products, are introduced. To explore a mixed integer nonlinear location model which is more consistent with the circulation characteristics of agricultural products. In the last part of the paper, taking the grape distribution of Beijing Xinfadi Co., Ltd as a practical example, using LINGO to solve the location model of the paper. It is proved that the location planning of agricultural products which takes into account the characteristics of complete cold chain and aging has the advantage of low comprehensive cost of cold chain.
