【摘要】：物资是企业正常运营的物质基础，供电企业物资需求量大，实效性强，直接影响企业的运行成本。对于企业整个物流过程中的每一个环节而言，无论是物资采购，还是物资的装卸、运输、配送等都离不开库存。简而言之，库存已经渗透到整个物流系统的每一个环节中。目前，大型企业的经营管理过程中，都非常重视库存优化工作。库存管理是一项巨大昂贵的投资，，需要支付巨额的成本。通过库存优化努力减少库存并降低库存成本，甚至追求零库存是库存管理乃至物流管理的中心与终极目标。本文主要针对供电企业库存积压状况而展开的，主要目标是采用合理的方法降低库存积压，使库存物资优化到合理水平上，降低库存资金占用，提高供电企业运行效率及竞争力。根据精益管理理论，结合供电企业仓储管理工作实际情况，采用六西格玛数据分析方法，对仓储物资管理中出现的问题进行了精细化的定义、测量、分析及改进。本文的主要研究内容如下： ⑴三大类物资：备品备件、待分配物资和在建项目物资是仓储物资的主要构成，是降低库存积压的分析重点，对于仓储物资现状分析有重要意义。 ⑵对备品备件库存特性进行分析，进而确定备品备件合理库存计算模型。 ⑶确定异常退料界定与控制方法，采用雷达图分析确定异常退料控制指标及其措施。 ⑷对在建物资库存结构分析，确定合理利用及处理积压物资措施，通过提高库存周转率实现在建物资库存量最优。
[Abstract]:The material is the material foundation of the normal operation of the enterprise, the material demand of the power supply enterprise is large, the actual effect is strong, it directly affects the running cost of the enterprise. For every link in the whole logistics process of the enterprise, no matter it is the material purchase, Or material handling, transportation, distribution and so on can not be separated from inventory. In short, inventory has penetrated into every link of the whole logistics system. At present, in the process of operation and management of large enterprises, Inventory management is a huge and expensive investment that requires huge costs. Through inventory optimization efforts to reduce inventory and reduce inventory costs, Even pursuing zero inventory is the center and ultimate goal of inventory management and logistics management. To optimize the inventory to a reasonable level, reduce the stock capital occupation, improve the operation efficiency and competitiveness of power supply enterprises. According to lean management theory, combined with the actual situation of storage management in power supply enterprises, this paper uses six Sigma data analysis method to define and measure the problems in warehouse material management. The main contents of this paper are as follows:. 1 three categories of materials: spare parts, materials to be distributed and items under construction are the main components of storage materials, which is the focus of analysis to reduce the inventory backlog, which is of great significance to the analysis of the current situation of storage materials. 2 analyzing the inventory characteristics of spare parts, and then determining the reasonable inventory calculation model of spare parts. (3) the method of defining and controlling abnormal material return is determined, and the control index and measure of abnormal material return are determined by radar chart analysis. (4) analyzing the stock structure of the materials under construction, determining the measures of reasonable utilization and disposal of the backlog, and realizing the optimal inventory of the goods under construction by increasing the turnover rate of the inventory.
