【摘要】：煤炭资源是我国非常重要的战略资源,是推动经济和社会发展必不可少的能源,并在我国一次能源结构中占据无可取代的地位。物流网络系统是一个复杂的动态系统,由多个相互联系、相互依存、相互影响的环节组成。与一般的物流网络相比,煤炭物流网络具有大宗货物运输、物流节点多、物流线路长、物流环节多等特点。通过对煤炭物流网络节点、物流运输线路以及煤炭供应商的合理选择来合理规划设计煤炭物流网络是减少网络物流成本的关键,尤其是煤炭的采购成本。因此,对煤炭的采购与供应物流网络优化问题的研究具有重要意义。本文首先在综述国内外研究现状基础上,提出了研究问题、构建了研究内容及框架：其次,回顾了物流网络、煤炭物流网络相关理论以及模型和方法,为论文的研究奠定了理论基础；第三,对煤炭采购与供应物流网络优化问题进行了深入分析,并提出了优化目标和优化内容；综合考虑煤炭用户的位置分布、运输距离、物流基地的建设成本以及煤炭的加工处理成本等因素,构建了基于煤炭物流基地选址的煤炭供应物流网络优化模型;考虑煤炭的采购成本、运输成本、中转综合费用以及煤炭供应商的服务质量等因素,构建了基于供应商选择的煤炭供应物流网络优化模型;根据建立的模型特点设计了相应的遗传算法。最后,将构建的煤炭供应物流网络优化模型和煤炭采购物流网络优化模型应用到豫北煤炭物流基地的实证研究中,并通过设计的遗传算法进行求解,得到豫北煤炭物流基地的最佳位置以及豫北煤炭物流基地的三种煤炭(动力煤、铸焦煤和化工煤)的最佳采购方案,为豫北煤炭物流基地的建设选址以及山西中南部铁路开通后的煤炭采购方案提供了决策依据。
[Abstract]:Coal resource is a very important strategic resource in our country, it is the indispensable energy to promote economic and social development, and occupies an irreplaceable position in the primary energy structure of our country. Logistics network system is a complex dynamic system, which is composed of several interrelated, interdependent and interactive links. Compared with the general logistics network, the coal logistics network has the characteristics of bulk cargo transportation, more logistics nodes, longer logistics lines and more logistics links. It is the key to reduce the cost of network logistics, especially the purchase cost of coal, to reasonably plan and design the coal logistics network through the rational selection of the nodes of the coal logistics network, the logistics transportation lines and the coal suppliers. Therefore, it is of great significance to study the logistics network optimization of coal purchasing and supply. On the basis of summarizing the current research situation at home and abroad, this paper puts forward the research issues and constructs the research content and framework. Secondly, it reviews the logistics network, coal logistics network related theories, models and methods. It lays a theoretical foundation for the research of this paper. Thirdly, the optimization problem of coal purchasing and supply logistics network is deeply analyzed, and the optimization objectives and contents are put forward, considering the location distribution of coal users, transportation distance, and so on. Based on the construction cost of logistics base and the processing cost of coal, the optimization model of coal supply logistics network based on the location of coal logistics base is constructed, considering the purchase cost and transportation cost of coal. The optimization model of coal supply logistics network based on supplier selection is constructed, and the corresponding genetic algorithm is designed according to the characteristics of the established model. Finally, the coal supply logistics network optimization model and the coal purchasing logistics network optimization model are applied to the empirical study of the coal logistics base in the north of Henan Province, and solved by the genetic algorithm. Get the best position of the coal logistics base in the north of Henan and the best purchasing plan of three kinds of coal (thermal coal, cast coking coal and chemical coal) of the coal logistics base in the north of Henan province. It provides the decision basis for the construction of the coal logistics base in the north of Henan province and the coal purchasing scheme after the opening of the central and southern Shanxi railway.
