英文摘要：

To promote the retrieval efficiency of Tier Captive Autonomous Vehicle Storage and Retrieval System（TCAVS/RS）,the influence factors was researched by using simulation and orthogonal experiment.The storage and retrieval process were analyzed,and the factors that affect retrieval efficiency was summarized.The simulation model for TCAVS/RS was established,and the simulation process based on orthogonal experiment was designed.24 different scenarios corresponded to inventory capacity 1200,1800 and 2400was simulated by using orthogonal approach.Vehicle/lift＇s speed,acceleration/deceleration and control strategy were selected as the observed factor.The experiment showed that control strategy stably affected the throughput performance in all scenarios,and new control software was developed to promote AVS/RS.The affect of velocity profile was different in different scenarios.In great column number scenarios,the better effectiveness was obtained by increasing maximum speed of vehicle;in small inventory scenarios,the better effectiveness was obtained by increasing acceleration/deceleration of lift.
