【摘要】：煤炭是推动我国经济发展的不可或缺的能源,对我国经济发展起到重大的作用。我国煤炭资源分布广泛,但是分布不均衡。我国煤炭物流的成本比较高,需要合理组织我国的煤炭物流。煤炭物流是大宗货物的物流,存在于煤炭从生产到用户整个过程之中。煤炭物流成本的高低,直接受到了煤炭物流网络构建的影响。煤炭物流网络是由煤炭物流节点和煤炭物流的线路组成。我国的煤炭物流节点多,分布广泛。我国的煤炭物流线路分布很复杂,铁路、水路、公路的选择相当的重要。煤炭企业要想减少煤炭物流的成本,那么煤炭物流网络服务节点的选择必须做好。本文根据我国煤炭物流网络的现状,考虑到煤炭需求、煤炭物流节点的特性、煤炭的运输方式等影响因素,运用组合数学、运筹学、系统工程、建模理论等数学知识,建立煤炭物流网络服务节点选择的模型,使煤炭物流网络的运行成本减少。这个模型能反映一般煤炭企业的煤炭物流网络结构,它是一个三阶段的供应链网络,包括的节点有煤矿、煤炭转运中心、煤炭储配中心和客户。模型建立之后,运用遗传算法进行求解。为了使求出的解更加准确,采用了一种新颖的遗传算法编码方式——基于优先权的编码。再结合遗传算法的选择、交叉、变异组成完整的遗传算法。根据建立的模型和遗传算法,再把它应用到具体的A煤炭公司中,通过具体案例来证明建立的模型和算法是正确的。
[Abstract]:Coal is an indispensable energy to promote the economic development of our country, which plays an important role in the economic development of our country. China's coal resources are widely distributed, but the distribution is uneven. The cost of coal logistics is relatively high in our country. It is necessary to organize the logistics of coal in our country reasonably. The logistics of coal is the logistics of large goods, and it exists in coal from production to use. The coal logistics network is directly affected by the construction of coal logistics network. Coal logistics network is composed of coal logistics nodes and coal logistics lines. China's coal logistics nodes are many and widely distributed. The distribution of coal logistics lines in China is very complex, railway, waterway, and highway are chosen quite well. Important, if coal enterprises want to reduce the cost of coal logistics, the choice of coal logistics network service nodes must be done well.
According to the present situation of China's coal logistics network, considering the coal demand, the characteristics of the coal logistics node, the influence factors of the coal transportation mode and so on, using the mathematical knowledge of combination mathematics, operation research, system engineering, modeling theory and so on, the model of selecting the node of coal logistics network service node is established so as to reduce the operation cost of the coal logistics network. This model can reflect the coal logistics network structure of the general coal enterprise. It is a three stage supply chain network, including the coal mine, coal transport center, coal storage center and customer. After the model is established, the genetic algorithm is used to solve the problem. In order to make the solution more accurate, a new genetic algorithm is adopted. The encoding method, based on the priority based coding, combined with the genetic algorithm selection, cross and mutation to form a complete genetic algorithm. Based on the established model and genetic algorithm, it is applied to the specific A coal company, and the model and algorithm are proved to be correct through a specific case.
