Storage cost is an important part of logistics cost, which is easy to control and manage. With the improvement of the technical level of warehousing logistics activities and warehousing efficiency, warehousing costs are also changing. However, there is a contradiction between the storage cost and the cost of other factors in logistics, such as transportation cost and distribution cost. Reducing the storage cost must be carried out on the premise of not reducing the overall service quality of enterprises. The common measures to reduce the storage cost are as follows: 1. Reducing the storage risk The longer the material is stored, the greater the storage risk. The most effective means to reduce the storage risk is to adopt the principle of "first in, first out", put all the storage materials in order, or take turns to access the storage materials, so as to reduce the storage time and loss of materials. Second, improve the utilization rate of warehouse capacity. There are two ways to improve warehouse utilization: increasing storage density and accelerating material turnover. Increasing the storage density can improve the utilization rate of unit storage area, so as to reduce the cost and investment of storage equipment, mainly including increasing the storage height, reducing the storage aisle and dense shelves. Third, improve the efficiency of warehousing operations. If the warehouse positioning system runs efficiently, it can greatly save the time of searching, storing and taking out, save a lot of materialized labor and live labor, prevent errors and facilitate inventory. Fourth, improve the accuracy of warehousing operations. Use the advanced management mode such as zero inventory to manage the warehouse, keep the known inventory in circulation and turnover, and realize the accuracy and minimization of the inventory. V. Determining the rationality of storage quantity The whole process of resources from procurement to production to customers needs to go through several stages, and almost every stage needs to be stored. By analyzing the optimal storage quantity of each logistics link from raw materials, semi-finished products and finished products, the speed of replenishing inventory is analyzed to minimize inventory level, storage waste and space occupation. Sixth, optimize the warehouse layout. Centralized and unified management of scattered storage points in the past, directly distributed in the form of regions. This method is beneficial to optimize the warehouse layout. On the other hand, maintaining and controlling inventory management through lean principles is the main trend of warehousing. In various fields of warehouses and distribution centers, these practices play a vital role in reducing storage costs. Through continuous improvement and commitment to lean warehousing, including real-time inventory management, warehouse managers can achieve a significant reduction in warehousing costs. These declines are mainly achieved by understanding the best advantages of effective inventory management and lean principles. 1, effective inventory management reduces the intangible waste of time, energy, opportunity cost and space that affects the overall cost of the warehouse. Spending too much time picking labels may lead to a decline in profits, and unnecessary repetitive walking of employees may lead to early fatigue and reduce the order completion rate. At the same time, redoing and returning goods are also consuming profits. 2. Optimizing the product flow is beneficial to reducing the warehouse cost. When considering product processes, it is important to remember how a single product process affects warehouse costs. The sudden choice of labels will lead to the attitude of workers changing from good to bad.
