基于六西格玛流程改进的库存管理优化

库存管理是企业用来控制实际库存问题的方法，主要帮助企业经营者确定何时补充订货、补充订货多少以及安全库存等问题。现有的库存控制研究往往只关注数学建模阶段的精确性，而对库存波动根源认识不足，导致数学模型越来越复杂、完善，但库存仍然居高不下、难以控制。本文针对该问题，提出了在库存管理中糅合六西格玛管理理念的思想，通过六西格玛方法揭示库存积压的根源，从源头着手，进行流程改进，从而达到库存优化、提高客户满意度的目的。文章通过实际案例证实了基于六西格玛理念的库存优化管理的有效性。

Optimization of Inventory Management Based on Six Sigma

Inventory management is the method that the organizations use to control actual inventory issues. It mainly helps practitioners to determine the time and quantity of supplementary ordering and other decisions relating to safety inventory. Current inventory control research always focuses on the precision of the mathematic modeling other than the root source of the inventory fluctuation, which makes the model more and more complicated while the inventory quantity still on a high level and hard to control. This paper, aiming at the contradiction, brings forward the thought of combining Six Sigma Concept with inventory management. Using Six Sigma Tools, the root source of inventory overstock will be revealed and according process can be improved, thus to achieve the goal of inventory optimizing and customer satisfactory elevating. An actual example is demonstrated in the paper to verify the validity of the Inventory-Management-and-Six-Sigma-Combination.
