To reduce labor intensity, eliminate errors, improve the level of warehouse automation and management, reduce loss of storage and transportation, improve logistics efficiency and many other advantages, has become an important technical equipment of modern logistics industry. As an important part of stereoscopic warehouse, the shelf of stereoscopic warehouse undertakes the functions of classified storage of goods, expanding storage capacity of warehouse and improving the degree of mechanized operation. As a mass customization product, the shelf of a stereo warehouse is designed according to the requirements of customers, logistics strategy, size of storage materials and so on. The existing design methods have many individual demands, large design workload, long design cycle, unable to respond to market demand quickly. There are many problems such as experience design, design knowledge disorder, design reusability and so on. Therefore, logistics equipment enterprises urgently need a set of intelligent enabling tools for shelf design to improve the efficiency and quality of shelf design and accelerate the pace of enterprise product innovation. It can quickly respond to the market demand and finally achieve the purpose of improving the market competitiveness of logistics equipment enterprises in China. In view of the above problems, this paper makes a thorough investigation and analysis on the existing design mode and method of the storage shelf, and puts forward the intelligent configuration design model of the shelf in the stereoscopic warehouse. The intelligent shelf configuration design system based on case-based reasoning (CBR), extension intelligent configuration selection design, parameterized template design and so on is developed.
