【摘要】：我国煤炭资源的分布状况和能源结构特点决定了,煤、电资源的开发及相应的电煤区域间调配问题成为影响我国经济健康发展和人民生活水平提高的关键因素之一。在煤炭资源产、销区域逆向分布的空间格局和电力供需缺口不断增加的社会环境下,如何借助有效的运力资源整合和配置来制定科学合理的电煤资源区域间调运方案是一个复杂且艰巨的系统工程问题。本文运用系统工程、交通运输以及运筹学等学科的理论和方法,从电煤物流系统分析出发,提出了一般化的电煤运输方案设计问题,并结合我国电煤运输现状和运输成本理论从电煤运输和电力生产两个层面,对电煤调运方案问题展开研究。首先,在电煤物流系统分析的基础上,从电煤连续生命周期出发,将电煤运输、电力生产等过程抽象为由不同物流服务组成的调运方案,并总结该问题的一般求解过程。其次,分析电煤资源的供需状况及未来走势。从我国电煤运输的格局规模、通道分布和供需趋势等角度重点分析铁路、公路、沿海海运以及远距离输电等运输供给方式,分析电煤运输存在的主要问题。第三,在运输方式成本构成、运输方式影响因素分析的基础上,综合考虑电煤物流系统中电力生产和煤炭运输两层问题,基于运筹学图论的基本原理,抽象电煤运输过程中各节点和路段关系,并对此过程中成本构成和能力约束进行抽象标定,建立电煤调运方案基本模型,并采用遗传算法对模型进行求解。最后,在对平庄煤业集团地理优势、煤炭外运通道以及运输存在问题和挑战进行分析的基础上,应用电煤调运方案选择优化模型对该矿区电煤调运方案的实际问题进行研究,运用遗传算法进行求解,并借助JAVA编程实现,得到总成本最低方案,进行方案对比分析。
[Abstract]:The distribution of coal resources and the characteristics of energy structure in China determine that the development of coal and electricity resources and the corresponding allocation of coal between regions have become one of the key factors that affect the healthy development of economy and the improvement of people's living standards. In the social environment where the production and distribution of coal resources are inversely distributed and the gap between supply and demand of electricity is increasing, It is a complicated and arduous system engineering problem how to make a scientific and reasonable plan for the regional distribution of thermal coal resources with the help of effective integration and allocation of transportation capacity resources. Based on the theory and method of system engineering, transportation and operation research, this paper puts forward the general design of coal transportation scheme based on the analysis of power coal logistics system. Combined with the current situation of coal transportation and the theory of transportation cost in our country, the paper studies the scheme of power coal transportation from two aspects of power coal transportation and electric power production. Firstly, based on the analysis of power coal logistics system, starting from the power coal continuous life cycle, the processes of coal transportation and power production are abstracted into different logistics services, and the general solving process of this problem is summarized. Secondly, the supply and demand situation and future trend of power coal resources are analyzed. From the angle of pattern scale, channel distribution and supply and demand trend of thermal coal transportation in China, this paper mainly analyzes the transportation and supply modes of railway, highway, coastal seaborne and long-distance transmission, and analyzes the main problems existing in thermal coal transportation. Thirdly, on the basis of analyzing the cost of transportation mode and the influencing factors of transportation mode, considering the two layers of electric power production and coal transportation in power coal logistics system, based on the basic principle of operational research graph theory, Abstract the relationship between nodes and sections in the process of coal transportation, and calibrate the cost structure and capacity constraints in the process, set up the basic model of power coal transportation scheme, and use genetic algorithm to solve the model. Finally, based on the analysis of the advantages of Pingzhuang Coal Industry Group, the existing problems and challenges of coal shipping channels and transportation, the practical problems of coal dispatching scheme in this mining area are studied by using the optimization model of coal dispatching scheme selection. Genetic algorithm is used to solve the problem, and JAVA programming is used to achieve the lowest total cost scheme, and the scheme is compared and analyzed.
