Description

Technical Field

[0001] The present invention belongs to the technical field of warehouse management, and in particular relates to a warehouse management system and method based on a portable self-service terminal. Background Art

[0002] In the modern logistics industry, warehouse management plays a vital role. With the continuous development of science and technology, intelligent warehouse management has become an inevitable trend in the development of the industry. Most of the existing warehouse management systems rely on manual operations, which are inefficient and prone to errors. The existing warehouse management system lacks intelligent means, focuses on basic functions such as purchase, sales, inventory, etc., and lacks real-time monitoring and early warning capabilities for inventory status. It cannot meet the efficient, accurate and intelligent needs of modern warehouse management, and the existing warehouse management system often has problems such as insufficient data processing capabilities and poor user experience. With the development of science and technology, traditional warehouse management methods can no longer meet the needs of modern enterprises. Most of the existing intelligent warehouse management systems are based on technologies such as the Internet of Things, big data, and cloud computing. Although they have improved the efficiency of warehouse management, there are still some problems, such as insufficient data processing capabilities, slow response speed, and low degree of intelligence.

[0003] In the prior art, there is a method of calculating the optimal path through a hybrid genetic algorithm to achieve the distribution and recovery of items, and at the same time, the items are placed in the corresponding position of the warehouse and the warehouse information is uploaded. In the management of item outbound delivery, the order demand and the warehouse storage volume are compared to achieve the outbound delivery of items. This method can improve the level of informatization and specialization of warehouse management and improve logistics efficiency.

[0004] However, this method only considers the shortest path, and does not comprehensively consider the intelligent management and scheduling of materials. Existing warehouse management still uses RFID for warehouse management.
