An AS/RS is being designed; randomized storage is

An AS/RS is being designed; randomized storage is to be used. One alternative being considered is to have each aisle be 70' tall and 310' long. The S/R has a horizontal speed of 425 fpm and a vertical speed of 80 fpm. It requires 0.40 minute to pick up or deposit a load. The activity level for the system varies during each shift. The heaviest operating period is a time during which a large number of retrievals must be per- formed. During peak activity, each S/R must be capable of performing 30 retrievals per hour and 10 storages per hour. It is expected that 100% of the storages will be per- formed with dual-command cycles. a. Can the system handle the required workload? Why or why not? b. II. during the peak period, the number of retrievals is 28 per hour and the number of storages is six per hour, what will be the utilization for each S/R?
