In recent years, the four- way shuttle storage system has attracted more and more attention. The study on the efficiency of inbound and outbound storage has become the key to solve the efficiency bottleneck of dense storage. In this paper, by modeling the four- way shuttle storage system, anylogic is used to simulate the inbound and outbound forms of standard elevator with chain machine and new elevator with two- way vehicles, and the efficiency is compared. It is concluded that when the dense storage reaches five floors and above, the efficiency of using the new elevator with two- way vehicles is higher, which provides a solution to solve the problem of storage congestion.
With the in-depth study of underground logistics system, the design and application of its transportation tools have become the key. This paper will discuss the innovative application of intelligent equipment -shuttle vehicle in the underground logistics system, construct the three-level network and operation platform of the underground logistics system, and study the new mode of underground logistics system based on shuttle vehicle, so as to play a driving role in the research of underground logistics.
