【摘要】：在物流网络中,配送中心是将供货点与需求点紧密联系在一起的重要桥梁。因此,配送中心的选址工作是物流系统分析中的一项核心内容。配送中心的合理选址不仅对提高物流系统效益有着重要的作用,而且是物流系统规划和整体优化的战略性决策问题。在现实生产经营活动中,选址区域内已经存在其他配送中心,此时进入该区域选址必然要考虑竞争的影响。本文的论题正是基于这种情况而提出的。本文首先介绍了论文选题的背景与意义,阐述了配送中心选址问题的国内外研究现状,接着对配送中心的概念及功能做了详细的综述。随后对配送中心选址原则与影响因素进行了分析,并总结出配送中心选址的现有方法。最后建立了有竞争的多配送中心选址模型并将改进后的蚁群算法应用于解决该问题。全文研究的主要内容如下： (1)模型建立。在对无竞争的多配送中心选址的模型研究基础上,考虑到竞争的影响,建立了有竞争的多配送中心选址模型。该模型考虑到竞争配送中心的存在,导致需求量的分配,综合考虑了配送量与成本之间的相互影响。 (2)算法改进。在对传统蚁群算法的研究基础上,针对传统蚁群算法存在搜索时间过长以及易陷入局部最优的缺点,从信息素增量自适应调整的角度出发进行改进算法,并验证其性能。 (3)实例应用。以仿真算例为基础,将改进的蚁群算法应用到有竞争的多配送中心选址问题上。结果表明该模型能较好的处理有竞争的多配送中心选址问题且改进的蚁群算法是合理有效的。希望本文能对加深配送中心选址的了解与认识起到帮助作用,对以后的研究起到参考作用。
[Abstract]:In the logistics network, the distribution center is an important bridge that connects the supply point with the demand point. The location of distribution center is a core content of logistics system analysis. The reasonable location of distribution center not only plays an important role in improving the benefit of logistics system, but also plays an important role in the analysis of logistics system. It is also a strategic decision problem for logistics system planning and overall optimization. In the actual production and operation activities, other distribution centers already exist in the location areas. The influence of competition must be taken into account when entering this region. The thesis of this paper is based on this kind of situation. This paper first introduces the background and significance of the selected topic of the paper, and expounds the domestic and foreign research status of the distribution center location problem. Then, the concept and function of distribution center are summarized in detail. Then, the principle and influencing factors of distribution center location are analyzed. Finally, the competitive multi-distribution center location model is established and the improved ant colony algorithm is applied to solve the problem. The main contents of this paper are as follows:. On the basis of the research on the location model of multi-distribution center without competition, considering the influence of competition, the model of multi-distribution center location with competition is established. This model takes into account the existence of competitive distribution center. The distribution of demand takes into account the interaction between distribution volume and cost. Based on the research of the traditional ant colony algorithm, aiming at the shortcomings of the traditional ant colony algorithm, such as long searching time and easy to fall into the local optimum, the improved algorithm is based on the adaptive adjustment of pheromone increment. And verify its performance. 3) case application. Based on a simulation example, The improved ant colony algorithm is applied to the competitive multi-distribution center location problem. The results show that the model can deal with the competitive multi-distribution center location problem and the improved ant colony algorithm is reasonable and effective. I hope this paper can help to deepen the understanding and understanding of distribution center location, and serve as a reference for future research.
