【摘要】：现阶段,随着我国对电力体制改革的不断深化,电网建设得到了迅速发展。然而电力物流系统中所呈现的高成本,低效率的现状却制约着电网企业的深入发展。电力物资配送中心选址则是电力物流系统规划中的基础和核心。论文从这一角度出发,对电力物资配送中心选址问题进行研究,目的是有效降低电力企业物资配送的费用,保证电力物资配送的时效性,提高电力物资的统一管理和调拨能力,这对电力行业物流系统的发展有着重要的意义。论文主要对电力物资配送中心选址问题进行深入研究。在广泛学习电力物资配送中心选址方法和国内外电网企业建立电力物资配送网络体系经验的基础上,明确了电力物资配送中心选址的目标和原则,总结了电力物资配送中心选址的影响因素,归纳了电力物资配送中心选址的程序和步骤。根据国家电网公司物资集约化管理中所提出的配送中心网络体系规划思路,设计了包含一级配送中心和二级配送中心的电力物资配送网络。在此基础上,建立了包含物资运输成本、物资存储成本以及时间惩罚成本在内的电力物资配送中心选址的数学模型。在对帝国主义竞争算法(简称ICA)进行学习研究的基础上,提出了基于微分进化的改进策略,使得殖民地国家之间可以进行信息交互并产生新的殖民地国家,一方面增强了种群的多样性,另一方面使势力大的殖民地国家能够保留下来,免于丢失,弥补了算法过早收敛以及丢失优秀个体的问题。将该改进算法与电力物资配送中心选址数学模型进行融合,用于求解电力物资配送中心选址问题。算例结果表明,论文所构建的模型和所提算法能够有效地降低总配送成本费用,控制配送中心的数量,有助于电力物资的统一管理和调拨,可以为将来的电力物资配送中心选址决策提供有利而可靠的依据。
[Abstract]:At present, with the deepening of electric power system reform in our country, power grid construction has been developed rapidly. However, the current situation of high cost and low efficiency in power logistics system restricts the further development of power grid enterprises. The location of power material distribution center is the foundation and core of power logistics system planning. From this point of view, this paper studies the location of power material distribution center. The purpose of this paper is to effectively reduce the cost of material distribution in electric power enterprises, ensure the timeliness of distribution of power materials, and improve the unified management and allocation capacity of power materials. This is of great significance to the development of power industry logistics system. This paper mainly studies the location of power distribution center. Based on the extensive study of the location method of power material distribution center and the experience of domestic and foreign power grid enterprises in establishing the power material distribution network system, the objectives and principles of the location of power material distribution center are clarified. This paper summarizes the influencing factors of power material distribution center location, and sums up the procedure and steps of power material distribution center location selection. According to the planning idea of distribution center network system proposed by State Grid Company in material intensive management, the power material distribution network including primary distribution center and secondary distribution center is designed. On this basis, a mathematical model of the location of power material distribution center is established, which includes material transportation cost, material storage cost and time penalty cost. Based on the study of the imperialist competitive algorithm (ICA), an improved strategy based on differential evolution is proposed, which enables the information exchange between the colonial countries and the emergence of new colonial countries. On the one hand, the diversity of the population is enhanced, on the other hand, the powerful colonial countries can survive and avoid loss, which makes up for the premature convergence of the algorithm and the loss of excellent individuals. The improved algorithm is combined with the mathematical model of power material distribution center location to solve the power material distribution center location problem. The results show that the proposed model and algorithm can effectively reduce the total cost of distribution, control the number of distribution centers, and contribute to the unified management and allocation of power materials. It can provide a favorable and reliable basis for the location decision of power distribution center in the future.
