Moreover, the existing warehouse management system often has problems such as insufficient data processing capacity and poor user experience. With the development of technology, traditional warehouse management methods cannot meet the needs of modern enterprises. Most existing intelligent warehouse management systems are based on technologies such as the Internet of Things, big data, and cloud computing, which have improved the efficiency of warehouse management, but still have some problems such as insufficient data processing capacity, slow response speed, and low degree of intelligence.
