Question:

An AS/RS is to be designed for a 48  54 unit load that is 50 high. There are 10 aisles; each aisle is 14 loads high and 60 loads long. There are to be sprinklers and no transfer cars. It takes 0.40 minute to perform a P/D operation. The S/R travels horizontally at a speed of 425 fpm and travels vertically at a speed of 80 fpm. During peak activity, each S/R in the system must be capable of performing 24 retrievals per hour and six storages per hour. During peak activity, it is expected that 100% of the storages will be performed with dual-command cycles. The maximum utilization of an S/R during peak activity must be less than or equal to 98%. Does the system satisfy the utilization constraint?
