华 华 中 科 技 大 学 硕 士 学 位 论 文 I I 摘 要 随着社会的发展，电能的触角已经延伸到世界的各个角落，平稳的电力供给是 维持社会正常生产生活的保证，也是对电力公司管理运营的基本要求。但是，随着 电力工业改革步伐的加快，电力公司在未来将面临更加惨烈的竞争，面对这样一个 市场环境，电力公司在保证较高服务水平的前提下，还必须在成本控制方面有所作 为，才能在生存和发展。 本文针对目前电力行业在成本控制手段方面还处于相对比较落后的现状，提取 仓储配送环节来对电力行业的成本控制进行优化，通过建立一个新的仓储配送网络 来实现库存费用、运输费用等的大幅度降低。本文同众多文献一样，假设不考虑库 存容量、进行连续检查的库存管理策略以及需求已知等，在此基础上，本文首先建 立了一个传统的仓储配送网络模型，模型以最小化成本为目标函数，组成部分包括 固定费用、库存费用以及运输费用。随后在传统模型的基础上，结合电力公司的经 营特点，考虑加入对配送距离的限制因素、库存的机会成本以及安全库存对运营成 本的影响，同时考虑中心仓库直接对用户进行配送，建立了一个更适合电力行业的、 以最低成本为目标函数的中心库/前沿库的两级仓储配送网络优化模型。最后利用算 例对传统模型和优化该模型进行分析对比，相应的算例结果表明，利用优化模型对 仓储配送网络进行重构，较大幅度的降低运营成本，同时相应的对需求的响应速度、 企业库存管理水平等方面有着显著的提升。 关键词：电力行业；仓储配送网络；备件仓库 II II Abstract With the development of society, electricity has been extended to reach all corners of the world, stable power supply is the assurance of maintenance in normal production and life, and is also the basic requirements in the power companies’ management and operation. However, with the accelerated pace of reform in the power industry, power companies in the future will face more fierce competition, in the face of such a market environment, the power companies want to survive and develop .they must not only to ensure the premise of a higher level of service and also to do something in controlling cost. In this paper based on the current situation of that the means of controlling cost is still relatively backward status quo in electric power industry, and select warehousing and distribution as the optimize area of controlling cost in the power industry, adopt a new warehousing and distribution networks to significantly reduce the cost in inventory, transportation, etc. This paper assume unlimited storage capacity, inventory management using a continuous inspection strategy, the demands are known as with many other documents, On this basis, this paper establish a traditional model of warehousing and distribution network and to minimize the costs as the objective function, the costs include the fixed costs, inventory costs and t
