【摘要】：钢铁行业是国民经济的支柱产业，它是衡量一个国家工业化水平高低的重要标志之一。但目前钢铁行业产能过剩，，产品结构不合理、成本高、内部无序竞争，价格战严重、布局不合理等问题不断凸显，我国的钢铁行业已经进入了高成本、低利润经营状态。而在这种状态下，钢铁行业中受影响最严重即是钢铁企业。钢铁企业要度过难关，需要降本增效，降低钢铁销售物流成本是很好的切入点。布局钢铁物流节点，构建钢铁销售物流网络是降低钢铁销售物流成本、缩短钢铁流通过程、提高客户服务水平、减少产成品库存、稳定市场价格、把钢铁物流从成本中心转变为利润中心的有利措施。同时目前对钢铁销售物流研究主要集中于销售物流管理、模式、信息化等方面，对钢铁物流节点定量选址及物流网络构建研究较少，因此本论文对钢铁销售物流节点的研究具有重要的现实指导及理论研究意义。首先，论文对物流、钢铁物流以及物流节点、钢铁销售物流节点相关理论进行详细的阐述，为后续钢铁销售物流网络节点的研究奠定理论基础。同时也对钢铁销售物流网络节点选址的原则及影响因素进行分析，为后续物流节点选址思路提供依据。其次，论文针对钢铁销售物流网络节点选址的问题提出了“两阶段”选址方法。首先针对备选点能够设立钢铁物流网络节点的综合实力进行评价，在评价过程中构建了相应评价指标体系，并且结合评价体系构建了基于粗糙集的评价模型，得到每个备选点的评价值，作为备选点初选的依据。然后在初选的基础上，构建以成本最低以及客户服务水平最大化为目标的多目标规划模型，并针对模型设立了相应计算过程，最后由LINGO软件进行求解，得到钢铁销售物流网络节点最终位置、数量以及不同种类产成品从工厂到物流节点的运输路径及相应运输量，不同种类产成品从物流节点到客户的运输路径及相应运输量。最后，论文以从J钢调研收集到的钢铁销售实际数据以及从统计年鉴和数据库查询到的数据为已知量代入构建的选址的模型中，检验模型的实用性。
[Abstract]:Steel industry is the pillar industry of national economy, which is one of the important symbols to measure the industrialization level of a country. However, the problems of overcapacity, unreasonable product structure, high cost, internal disordered competition, serious price war and unreasonable layout in the steel industry have become increasingly prominent. China's steel industry has entered a high cost and low profit management state. In this state, the steel industry is the most seriously affected is the iron and steel enterprises. In order to overcome the difficulties, iron and steel enterprises need to reduce cost and efficiency, and reduce the cost of steel sales logistics is a good entry point. The distribution of iron and steel logistics nodes, the construction of steel sales logistics network is to reduce the cost of steel sales logistics, shorten the steel circulation process, improve the level of customer service, reduce the inventory of finished products, and stabilize market prices. The favorable measures to change the steel logistics from cost center to profit center. At the same time, the research on the iron and steel distribution logistics is mainly focused on the management, mode, information, and so on, and the research on the quantitative location of steel logistics nodes and the construction of logistics network is less. Therefore, this paper has important practical guidance and theoretical significance for the research of iron and steel sales logistics node. First of all, the paper elaborates the related theories of logistics, steel logistics and logistics node, steel sales logistics node, and lays a theoretical foundation for the subsequent research of steel sales logistics network node. At the same time, the paper also analyzes the principle and influencing factors of node location in iron and steel distribution logistics network, which provides the basis for future logistics node location. Secondly, aiming at the problem of node location in steel distribution logistics network, this paper puts forward a "two-stage" location method. Firstly, the comprehensive strength of the steel logistics network node can be set up in the alternative point to evaluate, and the corresponding evaluation index system is constructed in the process of evaluation, and the evaluation model based on rough set is constructed in combination with the evaluation system. The evaluation value of each alternative point is obtained as the basis for the primary selection of the alternative point. Then, on the basis of the primary selection, a multi-objective programming model aiming at the lowest cost and maximization of customer service level is constructed, and the corresponding calculation process is established for the model. Finally, the model is solved by LINGO software. Finally, the final location and quantity of the nodes in the distribution logistics network of iron and steel are obtained, as well as the transportation path and the corresponding transport volume of different kinds of finished products from the factory to the logistics node, and the transportation path from the logistics node to the customer of different kinds of finished products and the corresponding transport volume. Finally, the paper uses the actual data collected from J steel research and the data from statistical yearbook and database to test the practicability of the model.
