【摘要】：仓库是物流中的重要环节，储存功能相对于整个物流体系来说，既有缓冲与调节的作用，也有创值与增效的功能，而且仓库环节运作效率也影响着整个供应链的效率和成本。仓库布局问题是仓储问题中重要的一环，布局问题中最主要的方面是利用存储策略进行货位分配。合理的存储策略不仅可以使仓库的存取更有效率，同时也能大大降低订单拣选和库存盘点的难度，有效降低运作成本。本文主要对东风本田武汉二厂冲压科库存区布局问题进行研究。通过对工厂的现状进行分析，将工厂面临的问题归结到了布局问题上。在寻找合适的存储策略上，不仅要符合仓库布局的基本原则，也考虑到汽车冲压件品种多、规格相对较小的特性。本文使用了一种基于COI的改进分类存储策略，该存储策略结合了定位存储和分类存储的优点。围绕该存储策略，提出了解决工厂实际问题的流程。首先，对仓库区进行货格划分，，使得一个货格对应存放一种货物。然后，把货物按照COI值进行分类，在仓库中为每个类别划分出对应的区域。最后，在每一个分类区域当中进行定位存储，即货位分配，通过建立拣选成本最小化的数学模型来计算每种货物具体对应的货位，这样就完成了一种分类存储和定位存储结合的改进存储方案。通过结合实际数据计算，得到了一个较优的货位分配结果，也提出了在每个货格中实现先进先出的参考方法。针对不确定因素的问题，提出了一些参考建议，比如在仓库中预留缓冲区域来应对突发状况等。本文通过实际的案例分析，对仓库布局的研究具有广泛的实践意义，对相似的零部件制造企业有较好的借鉴作用，为类似企业在仓库布局上提供了值得参考的理论依据。
[Abstract]:Warehouse is an important link in logistics. Compared with the whole logistics system, storage function has the functions of buffering and adjusting, creating value and increasing efficiency. The efficiency of warehouse operation also affects the efficiency and cost of the whole supply chain. The most important aspect of the layout problem is the use of storage strategy for the allocation of goods. Reasonable storage strategy can not only make warehouse access more efficient, but also greatly reduce the difficulty of order picking and inventory inventory, and effectively reduce the operation cost. This paper mainly studies the layout of stamping section inventory area in Dongfeng Honda Wuhan No.2 Plant. By analyzing the present situation of the factory, the problems faced by the factory are reduced to the layout problem. Not only should it conform to the basic principles of warehouse layout, but also take into account the large variety of automotive stamping parts and relatively small specifications. This paper uses an improved classification and storage strategy based on COI. The storage strategy combines the advantages of location storage and classified storage. Around the storage strategy, a process to solve the practical problems of the factory is proposed. Firstly, the warehouse area is divided so that a cargo box can store one kind of goods. The goods are classified according to the COI value, and each category is divided into corresponding areas in the warehouse. Finally, the goods are located and stored in each classified area, that is, the distribution of the goods. By establishing a mathematical model to minimize the picking cost to calculate the specific location of each cargo, an improved storage scheme combining classified storage with location storage is completed. In this paper, we get a better result of distribution of goods, and propose a reference method for realizing first-in-first-out in each cargo box. In view of the problem of uncertain factors, some reference suggestions are put forward. For example, in the warehouse reserved buffer area to deal with emergencies and so on. Through the actual case analysis, this paper has extensive practical significance to the warehouse layout research, has the good reference function to the similar parts manufacturing enterprise, has provided the worth reference theory basis for the similar enterprise in the warehouse layout.
