【摘要】：随着人们生活水平和健康意识的提高,人们对食品是否新鲜,质量能否得到保证的关注度也越来越高。冷链物流的诞生满足了人们对食品质量和新鲜度的要求。冷链物流的实质是保证食品的质量,具体操作就是将食品储存在其所需的低温环境中,直到产品到达消费者手中。冷链物流在我国的发展尚不成熟,冷链体系也不健全,所以对于冷链物流的研究是十分必要的。冷链物流中,当属冷链配送中心选址的研究最为关键,目前,我国对其理论研究尚不深入,因此,对于冷链物流配送中心选址的理论探讨是十分必要的。另外,由于冷链配送中心连接着生产者与销售者,如若冷链配送中心选址正确,就能降低物流成本、整合社会资源、减少交通压力等。所以,无论从理论上还是现实利益上,冷链物流配送中心的选址研究都极其重要。本文首先详细分析了该课题的研究背景,阐述了该课题研究的目的与意义,总结了国内外冷链物流以及配送中心选址的相关理论研究。其次,探讨了国内外冷链物流的发展情况,重点分析了国内冷链物流在发展过程中存在的问题,突出了课题研究的意义。然后,分析了冷链物流配送中心选址的相关影响因素,建立了评价指标体系,提出了一种基于UEOWA和ULHA算子的多属性决策方法来选择候选配送中心地点。最后,根据第三方冷链物流的特点,建立了以总成本和服务水平最优化的双目标选址模型。在模型求解过程中,运用惩罚成本这一概念对服务水平最大化目标进行了转化,得到了以成本最低的单目标模型,并运用遗传算法对模型进行求解,运用具体事例对其进行分析,证明了本论文中选址方法的可行性。本论文不仅运用定性与定量方法相结合的方式对冷链配送中心进行选址,而且利用总成本最低和服务水平最大化两目标建立数学模型,更加贴近现实情况,给企业进行配送中心选址提供了理论依据。
[Abstract]:With the improvement of people's living standard and health consciousness, people pay more and more attention to whether food is fresh or not. The birth of cold chain logistics meets the requirements of food quality and freshness. The essence of cold chain logistics is to ensure the quality of food. The concrete operation is to store the food in the low temperature environment it needs until the product reaches the consumer's hand. The development of cold chain logistics in our country is not mature, the cold chain system is not perfect, so the research on cold chain logistics is very necessary. In cold chain logistics, the research on the location of cold chain distribution center is the most important. At present, the theoretical research on the location of cold chain logistics distribution center is not in-depth. Therefore, it is very necessary to discuss the location theory of cold chain logistics distribution center. In addition, because the cold chain distribution center connects producers and sellers, if the location of cold chain distribution center is correct, it can reduce logistics cost, integrate social resources, reduce traffic pressure and so on. Therefore, it is very important to study the location of cold chain logistics distribution center in both theoretical and practical interests. Firstly, this paper analyzes the research background of this topic in detail, expounds the purpose and significance of the research, and summarizes the related theoretical research of cold chain logistics and distribution center location at home and abroad. Secondly, the development of cold chain logistics at home and abroad is discussed, and the problems existing in the development process of domestic cold chain logistics are emphatically analyzed, and the significance of the research is highlighted. Then, the related factors of cold chain logistics distribution center location are analyzed, the evaluation index system is established, and a multi-attribute decision-making method based on UEOWA and ULHA operator is proposed to select the candidate distribution center location. Finally, according to the characteristics of the third-party cold chain logistics, a two-objective location model based on the optimization of total cost and service level is established. In the process of solving the model, the goal of maximizing service level is transformed by using the concept of penalty cost, and a single objective model with the lowest cost is obtained, and the model is solved by genetic algorithm. The feasibility of the location selection method in this paper is proved by the analysis of concrete examples. This paper not only uses the combination of qualitative and quantitative methods to select the cold chain distribution center, but also establishes the mathematical model by using the goals of minimum total cost and maximum service level, which is closer to the reality. It provides a theoretical basis for the location of distribution center for enterprises.
