Simulation research on storage-retrieval strategies of stereo garages

To solve the existing problem of stereo garages, this paper chooses vertical lifting stereo garages as studying object and average waiting time as evaluation indicators to simulate two different types of storage-retrieval strategies of stereo garages, First Come First Service (FCFS) strategy and Cross-access strategy, by FlexSim. Besides, in order to analyze the influences on the total waiting time resulting from two strategies quantitatively and precisely, this paper adopts a statistical method, “Paired-t Confidence Interval”, to analyze results.
