An automated storage/retrieval system for work-in-process has five aisles. The storage racks in each aisle are 10 m high and 50 m long. The S/R machine for each aisle travels at a horizontal speed of 2.0 m/s and a vertical speed of 0.4 m/s. Pick and deposit time = 15 s. Assume that the number of single command cycles per hour is equal to three times the number of dual command cycles per hour and that the system operates at 90% utilization. Determine the throughput rate (loads moved/hour) of the AS/RS.
