The length of one aisle in an AS/RS is 100 m and its height is 20 m. Horizontal travel speed is 4.0 m/s. The vertical speed is specified so that the storage system is "square in time," which means that L/vy = H/vz. The pick-and-deposit time is 12 s. Determine the expected throughput rate (transactions per hour) for the aisle if the expected ratio of the number of transactions performed under single-command cycles to the number of transactions performed under dual-command cycles is 2:1. The system operates continuously during the hour.
