An AS/R system is being designed for 48  42 unit loads that are 45 high. One of the design alternatives involves 12 aisles, no transfer cars, 1440 openings per aisle, 12 levels and 60 columns of storage on each side of the aisle, and sprinklers. The S/R will travel horizontally at an average speed of 320 fpm; simultaneously, it will travel vertically at an average speed of 75 fpm. The time required to pick up or deposit a load equals 0.25 minute. Each S/R will have to store and retrieve at a rate of 15 storages per hour and 15 retrievals per hour. It is felt that 70% of the storages and retrievals will be performed on a dual-command cycle. What will be the utilization of each S/R? What will be the cost of the building if a 25-high building costs $20/ft2? What will be the cost of the AS/RS if a central computer console is used and if each unit load weighs 2,500 lb?
