【摘要】：随着经济的迅速发展，现代服务集聚区的不断形成，对物流网络的结构提出了更高的要求。优化设计物流网络，关系着现代物流企业的经济效益，也反映了其综合管理水平和市场竞争力，物流网络优化设计涉及多方面，其中设施选址优化、路径优化、选址-分配问题、选址-库存问题等逐渐成为国内外学者探讨和研究的重点。以现有的研究为基础，，本文以现代服务集聚区的多级物流配送网络为研究对象，针对多级确定物流网络的优化设计问题与考虑碳排放的物流网络优化设计问题进行研究，旨在降低物流成本，提高物流企业的经济效益。本文首先阐述了服务集聚区与现代物流网络的特点、物流网络的构成、物流网络模型分类、费用分析以及求解算法等相关理论知识。其次，针对已存在的多级物流网络没有充分考虑物流节点开关状态的问题，根据产品需求量、单位运输费用随季节不断变化等特点，通过调整节点状态，以物流网络的总体费用最小为优化目标，构建了带有能力约束的多级物流网络优化设计问题的数学模型；利用改进后的模拟退火算法进行实例仿真，验证了模型的有效性。最后，针对考虑碳排放的物流网络优化设计问题，建立了考虑碳排放成本的物流节点选择和需求匹配模型，解决了物流网络中物流节点选择、节点间的需求匹配等多种决策问题。对“不考虑碳排放成本”与“考虑碳排放成本”两种情况进行仿真分析，结果表明，考虑碳排放成本的物流网络比不考虑碳排放成本的传统网络更具有现实意义。本文研究了适合各种经济规模和配送范围的物流网络优化设计问题，为企业进行物流网络优化设计提供了决策支持。由于时间短暂，针对集聚区物流网络优化设计问题，本文研究的还不够充分，今后还可以针对物流网络优化设计的可靠性方面做进一步的研究和探讨。
[Abstract]:With the rapid development of economy and the continuous formation of modern service agglomeration area, the structure of logistics network is demanded higher. The optimization of logistics network is related to the economic benefit of modern logistics enterprise. It also reflects the level of comprehensive management and market competitiveness, logistics network optimization involves many aspects, including facility location optimization, path optimization, site-allocation problems, The site-inventory problem has gradually become the focus of scholars at home and abroad. Based on the existing research, this paper takes the multi-level logistics distribution network of modern service agglomeration area as the research object. In order to reduce the logistics cost and improve the economic benefit of logistics enterprises, the optimization design of multi-level determined logistics network and the optimization design of logistics network considering carbon emissions are studied. This paper first describes the characteristics of service agglomeration area and modern logistics network, the composition of logistics network, the classification of logistics network model, cost analysis and solving algorithm and other relevant theoretical knowledge. In view of the fact that the existing multilevel logistics network does not fully consider the switching state of logistics nodes, according to the characteristics of product demand and unit transportation cost changing with the seasons, the node state is adjusted. Taking the minimum total cost of logistics network as the optimization goal, the mathematical model of multi-level logistics network optimization design with capability constraints is constructed, and the improved simulated annealing algorithm is used to simulate the problem. Finally, aiming at the optimization design of logistics network considering carbon emissions, a logistics node selection and demand matching model considering the cost of carbon emissions is established, which solves the logistics node selection in the logistics network. The simulation analysis of "not considering the cost of carbon emissions" and "considering the cost of carbon emissions" shows that, The logistics network considering the cost of carbon emissions has more practical significance than the traditional network which does not consider the cost of carbon emissions. In this paper, the optimal design of logistics network suitable for various economic scale and distribution scope is studied, which provides decision support for the optimization design of logistics network for enterprises. Because of the short time, the optimization design problem of logistics network in agglomeration area is studied. The research in this paper is not enough, and the reliability of logistics network optimization design can be further studied and discussed in the future.
