【摘要】：湖南华菱钢铁集团是由湖南三大钢铁企业——湘钢、涟钢、衡钢联合组建而成。1997年华菱集团组建之初,钢产量只有236万吨,经过十几年的跨越式发展,跻身全球钢企前20名榜单,2011年粗钢产量已达1543万吨。按照公司发展战略,华菱集团未来两年内的钢产量的规模目标将进一步扩大,需要进口的铁矿石也将进一步增加,未来钢材的出口量也逐步上升。华菱集团的快速发展对企业的物流提出了更高的要求,物流如何适应企业的发展是亟待解决的问题。由于地处内陆省份,三家钢厂又分布在不同的城市,铁路运输一直是华菱集团主要的物流方式,公司接近70%的进口矿依靠铁路进厂。进口矿从宁波、湛江、防城港等港口卸载后经铁路运到企业所在地。但是,随着华菱集团生产规模的扩大和产能的提高,铁路运输发展已明显滞后,很难满足华菱高速发展形成的物流增长需求。因此,华菱钢铁要发挥水运的优势,优化水路运输系统,扩展水路运输量,达到保障华菱集团生产需求,提高物流效率,降低综合物流费用,提高企业竞争力的目的。论文首先概述了华菱钢铁集团的概况以及进出口水运物流需求,介绍了华菱钢铁目前的原材料和产成品的物流系统,并分析了其当前存在的主要问题和未来的发展趋势。接下来通过分析华菱钢铁进口铁矿石水路运输必经的长江和湘江两个水运通道条件,以及可选的沿海中转港以及内河中转港的条件,得到了华菱钢铁进口铁矿石水运物流的运输模式,并为这几种模式选择了合适的运输船型。文章然后分析了华菱钢铁的进口铁矿石水运物流系统的目标以及约束条件,建立了华菱钢铁水运物流系统的运输费用最小模型,并使用遗传算法对该模型进行求解,从多种水运方案中选出了费用最小的方案,即得到了华菱钢铁的最佳进口铁矿石水运物流系统方案。文章最后从华菱集团的内部和外部两个方面提出了提高接卸港能力、建设整体物流信息系统、培养物流人才、加强与港口和船公司的合作等相应的措施和建议,以此来保障新水运方案的顺利运行。
[Abstract]:Hunan Valin Iron and Steel Group is a joint formation of three major iron and steel enterprises in Hunan-Xianggang, Lianyuan Steel and Heng Steel. When the Valin Group was established in 1997, its steel output was only 2.36 million tons. After more than 10 years of leapfrog development, Among the world's top 20 steelmakers, crude steel production in 2011 has reached 15.43 million tons. According to the company's development strategy, Valin's target for steel production in the next two years will be further expanded, the amount of iron ore to be imported will also be further increased, and steel exports will gradually increase in the future. The rapid development of Valin Group puts forward higher requirements for the logistics of enterprises, and how to adapt the logistics to the development of enterprises is an urgent problem to be solved. Because of the inland provinces and the distribution of three steel mills in different cities, rail transport has been the main logistics mode of Valin Group, and nearly 70% of its imported mines rely on railways to enter the plant. Imported mines from Ningbo, Zhanjiang, Fangchenggang and other ports unloaded by rail to the location of the enterprise. However, with the expansion of production scale and the improvement of production capacity of Valin Group, the development of railway transportation has obviously lagged behind, and it is difficult to meet the demand of logistics growth formed by the rapid development of Valin. Therefore, Valin Iron and Steel should give full play to the advantages of water transportation, optimize the waterway transportation system, expand the waterway transportation volume, and achieve the purpose of ensuring the production demand of Valin Group, improving the logistics efficiency, reducing the comprehensive logistics cost, and improving the competitiveness of the enterprises. Firstly, the paper summarizes the general situation of Valin Iron and Steel Group and the demand of import and export shipping logistics, introduces the logistics system of raw materials and finished products of Valin Iron and Steel Co., Ltd., and analyzes the main problems and future development trend of Valin Iron and Steel Group. Next, through the analysis of the conditions of the two waterways of the Yangtze River and the Xiangjiang River, which are necessary for the import of iron ore by water from Valin Iron and Steel, as well as the conditions for the optional coastal transit ports and inland river transit ports, The transport mode of imported iron ore transport logistics for Valin Iron and Steel is obtained, and the suitable transport ship type is selected for these modes. Then, the paper analyzes the objectives and constraints of the imported iron ore transportation logistics system of Valin Iron and Steel, and establishes the minimum transportation cost model of the freight transport logistics system of Valin Iron and Steel, and uses genetic algorithm to solve the model. The least cost scheme is selected from various water transportation schemes, that is, the best scheme of imported iron ore transport logistics system for Valin Iron and Steel is obtained. Finally, the paper puts forward the corresponding measures and suggestions from the internal and external aspects of Valin Group, such as improving the port handling capacity, building the whole logistics information system, training logistics talents, strengthening the cooperation with port and shipping company, etc. In order to ensure the smooth operation of the new waterway scheme.
